800 Series - RC Networks ECL Terminator Circuits
General Description
Digital systems incorporating Emitter
Coupled Logic (ECL) or other ultra-high
switching speed logic families will require
signal termination to prevent transmission line effects such as reflections and
ringing due to fast transition times.
Bourns 800 series resistor capacitor networks are ideal for termination of high
speed transmission lines. Each network
is composed of resistors for parallel
termination and bypass capacitor(s) for
cross talk noise reduction.
The 5 conformal coated SIP circuit variations offered are as follows.

Application Notes – EMI/RFI Filters 601 Series
General Description
Continual advances in digital IC technology are creating
stringent demands on EMI/RFI levels in equipment.
EMI/RFI low pass filters are required in personal
computers, data terminals, test equipment and process controllers for high frequency suppression into or out of electronic equipment.
Filter Selection and Design Considerations
A final consideration is the insertion loss. As mentioned
previously, the voltage drop across the two resistors will
attenuate the voltage reaching the load. Normally, logic high
and low levels will still be within valid limits. The signal
attenuation can be minimized by choosing small R values relative to the load impedance. Typical values for R range from
10 to 50 ohms.
Bourns Low-pass Filters for EMI/RFI Suppression
The “roll-off” frequency fc, defined as the frequency at
which the filter passes one-half the power it receives at its
input terminal, can be specified from the low megahertz
range up to about 100MHz. This frequency, also known as
the “-3 dB” frequency, will be determined by the R and C
values chosen. Custom resistor and capacitor values are
available to optimize system performance.
The specification of these values will depend on constraints relating to noise frequencies, system performance
and driver loading. The following procedure is suggested to
choose appropriate values of R and C.
The first step is to determine the desired roll-off
frequency of the filter, which will lie between the signal
frequency and the dominant frequencies of the EMI/RFI
noise. By determining the pole of the filter (setting the
denominator of the transfer function equal to zero), the
roll-off frequency can be expressed in terms of R and C:
fc =
RS + RL + 2R
2πC(R + RS)(R + RL)
Furthermore, the RC combination must be chosen so
that the additional RC time delay will not result in exceeding
the sampling window of the receiving IC, due to excessive
lengthening of signal rise and fall times.
Rise time from 10% to 90% of the waveform amplitude
can be calculated in terms of the circuit’s RC time constant
using the 1 –exp (–t/RC) relationship for a charging capacitor.
At 10%, t L = 0.1 time constants, and at 90%, tH = 2.3 time
constants. “Time constant” equals RthC, where Rth is the
Thevenin-equivalent resistance as seen by the capacitor.
Therefore, equating the difference in the two times to
the maximum tolerable rise (or fall) time:
tmax = t H - tL = 2.2RthC
tmax = 2.2

EMI/RFI Filters 601 Series
Reducing EMI/RFI
The radiation of electromagnetic interference and radio frequency interference (EMI/RFI) to the environment is a pressing
concern for many manufacturers of electronic equipment.
According to FCC regulations (Parts 15 and18), emissions must
not exceed certain maximum levels depending on whether the
equipment is for strictly industrial use or also for residential use.
A graphical representation of these limits is shown in Figure 1.
Similar restrictions apply to equipment sold in Europe (VDE
0871, a West German standard), Japan (VCCI), and to the military (MIL-STD-461/462.)

basic T-Filter configuration
Under steady state conditions, the capacitor C offers an infinite impedance to the DC component of the input waveform
(which will be assumed for the moment to be entering from the
left side). Thus, the DC component of the signal voltage is
passed to the load, but reduced in value by the voltage drop
across the two resistors.
The impedance of C becomes lower at higher (noise) frequencies. Thus, the noise component of the signal faces a voltage
divider consisting of the first resistor (R) and C. At the high frequencies of the noise component, R will be much greater than
the impedance of C, therefore, most of the noise voltage will be
dropped across the resistor. Almost no noise current flows
through the load and, therefore, will hardly affect the DC voltages (i.e., the signal) across the load.
Since the filter is symmetric, its principle of operation is the
same for waveforms traveling in the opposite direction, in which
case the voltage divider is formed by the second resistor and
the capacitor. Such a symmetrical design is useful for filtering
signals on a bidirectional bus.
Assuming purely resistive source and load impedances, the
transfer function is given by:
Vout
Vin
=
RL
jωC(R + RS)(R + RL) + (RS + RL + 2R)
Several approaches are available today to control EMI/RFI
emissions, including grounded metal enclosures, shielded
cables, judicious component placement and interconnect
designs, power-supply decoupling, and low-pass filtering of signal lines.
Low-pass filtering can be effective for EMI/RFI filtering when
the noise components to be rejected occur at frequencies higher than the signal frequency (to be passed). For these situations,
Bourns has developed low-pass resistor-capacitor filter networks which are ideal for board-level EMI/RFI filtering.
A typical application would be to filter signal lines between
RS-232 drivers and their corresponding connectors. In such low
to medium frequency applications, these networks represent a
more useful (and economical) solution than inductive type filters
such as ferrite beads. In fact, ferrite beads become mostly ineffective below 10MHz.
The basic “T” configuration (Figure 2) is a standard R-C network available in versions for 7 or 8 input lines. The 8 input-line
version is available in both through-hole DIP and surface-mount
models.

RC Terminator Networks 700 Series
General Description
This series of RC Networks is designed to eliminate transmission line effects, such as signal reflections and ringing which
influence high speed CMOS. The Networks capacitor blocks
DC currents while acting as a short circuit during signal transmitions, thus reducing power consumption. The capacitor also
holds the bus at the last logic level to avoid excessive currents.
Block Diagram Of CPU/BUS Configuration
Bus termination (in this case, RC termination technique)
considerably reduces overshoots and ringings.
Transmission lines require termination when the time it takes
the signal to travel from one end of the line to the other (the
propagation delay) amounts to 1/2 or more of the edge rate of
the signal (signal rise time or fall time). In other words, termination is required when:
Tpd > (1/2)Te
Te = edge rate
Tpd = propagation delay
Present high-speed logic families have typical rise times of 2
nanoseconds, while the propagation delay of a common PCB is
about 1.77 ns per foot. Applying the above relationship, a transmission line will require termination if it is longer than 7 inches.
High performance systems will commonly need Bourns termination networks for CPU address, data, and control lines. In
addition, clock inputs, write and read strobe lines, chip select or
output enable lines of high speed devices such as static RAMs,
PROMs, and PLDs will also need termination networks.
Bus Termination Applications Of Bourns Networks
At high frequencies, the traces on a printed circuit board act
as transmission lines—in which impedance mismatches can
cause distortion of signals on that line. Terminating the lines
with resistor or resistor-capacitor networks provides the means
to match impedances and reduce signal distortion.

RC Terminator Networks 700 Series

For designers developing high performance systems, exact
termination resistances which account for line loading may be
desirable. This resistance (or equivalent resistance) can be calculated using the formula:
Rterm =
Zo
1
8
V 1 + Cd / Co
where Zo is the characteristic impedance of the line, Cd is the
total capacitance associated with the receiving devices (typically
5 pF per input gate) or other loads off the line, and Co is the
intrinsic capacitance of the line.
The series termination technique suppresses reflections at the
driving device should any waveforms be reflected back from the
driven end of the line. Series termination preserves power since
there is no current path to ground or Vcc as in the other methods. However, this technique results in incident signals that
transition slowly. It is also not appropriate for distributed loads
due to the half-amplitude waveforms which exist at intermediate
points along the line.
RC termination represents a compromise between power consumption and effect on performance. Its principle of operation is
similar to parallel termination, but the capacitor blocks the DC
component of the signal, thus reducing power consumption.
However, the effectiveness of this method depends on the frequency and duty cycle of the application. RC termination also
can be an expensive technique if implemented using discrete
components rather than a network.

Bourns Emitter Coupled Logic Terminator 800 Series
Typical Application
A typical application using a Bourns 801 RC Network in conjunction with a 10K ECL design is shown below. Vee is typically
connected to -5.2 volts (10K ECL) or -4.5 volts (100K ECL). Vcc
is typically connected to GND. Vtt is typically connected to -2.0
volts. The 801 network shown below can terminate up to 6
transmission lines and provides a 0.01 µF capacitor to reduce
cross talk and feedthrough effects.
The actual, effective delay and impedance due to
loading from stubs or additional devices off the line will be:
Tpd’ = Tpd
√1 + Cd/Co
Zo’ =
√1 + (Cd/Co)
Zo
Where Co = intrinsic capacitance of the line
Cd = capacitance due to loading and stubs
off the line
Tpd = basic propagation delay of the line
Zo ....= basic impedance of the line

Transmission Line Considerations
In high speed circuit applications, the signal propagation delay
(Tpd) and characteristic impedance (zo), along a printed circuit
board line must be taken into consideration. In general, if the
two-way delay along the line is greater than the rise or fall time
of the signal, then controlled impedance techniques (i.e., termination) must be utilized to prevent undesirable ringing or overand undershoots. The delay and impedance can be calculated
by knowing the intrinsic inductance (Lo) and capacitance (Co) of
the line:
Tpd =
Zo =
√LoCo
√Lo/Co
Where Tr = rise or fall time
Tpd = propagation delay per unit length
The above equation implies that the faster the edge rate or the
higher the loading on the line (i.e., higher fanout), the more likely
that termination will be necessary for a given line length.
Parallel Termination
For maximum circuit performance or distributed loads, parallel
termination is the most appropriate technique. A parallel terminated line uses a resistor connected to -2 volts (ECL application)
at the receiving end. The resistor value matches the characteristic impedance of the line (Zo), thereby producing zero reflection
at the receiver. In addition, the terminating resistor also provides
output pull down, so a separate pull down resistor at the driving
end is unnecessary.

Bourns Emitter Coupled Logic Terminator 800 Series
Bourns 801, 802, and 804 conformal coated SIP resistor
capacitor networks are designed to terminate 6 transmission
lines using the parallel termination technique. A 0.01 µF capacitor(s) is provided in each network to help maintain a solid Vtt
level within the package, mitigating any potential cross talk or
feedthrough effects. The 804 circuit also contains a 0.1 µF
capacitor for bypassing the Vee supply.
R1 and R2 are calculated using the following equations:
R2 = (Vee/Vtt)*Zo
R1 = (R2*Vtt)/(Vee-Vtt)
For a 10K ECL supply voltage of -5.2V and Vtt of -2V:
R2 = 2.6*Zo
R1 = R2/1.6
For a 100K ECL supply voltage of -4.5V and Vtt of -2V:
R2 = 2.25*Zo
R1 = R2/1.25
Parallel Termination Technique
Thevenin Equivalent Parallel Termination
Parallel termination in ECL applications uses -2.0 volts as the
terminating voltage. This represents a disadvantage since a
separate Vtt power supply must be available (Vee = -5.2 volts,
Vtt = -2.0 volts). For systems in which a separate -2.0 volt supply is not available, the use of a Thevenin equivalent arrangement, although resulting in higher power consumption, provides
a convenient solution.
Bourns 803 and 805 conformal coated SIP resistor capacitor
networks are designed to terminate 8 transmission lines using
the Thevenin equivalent parallel termination technique. Again, a
0.1 µF capacitor is provided to help maintain a solid Vee level
within the package, mitigating any potential cross talk or
feedthrough effects. The 803 is designed for use with 10K ECL
whereas the 805 is designed for use with 100K ECL.

Dual Terminator Resistor Network
The Dual Terminator (or Thevenin equivalent) Network is commonly used for TTL
dual-line termination and pulse squaring or
ECL line terminations. In ECL line terminator, R2 functions as an emitter pull-down
resistor and is normally tied to the most
negative supply voltage to provide proper
line currents. R1 is normally tied to ground
and functions as the termination resistor
and in parallel with R2 provides the characteristic impedance of the transmission line.
This results in a zero reflection coefficient
of this line to eliminate reflections.
R1 is now guarded and an accurate
measurement can be made.
The Dual Terminator circuit is available in both
SIP and DIP configurations, as shown below.
To test the first R2 resistor, connect the
ohmmeter measurement leads between pin
1 and pin 2. Connect the guard lead to pin
8. The first R2 resistor is now guarded and
an accurate measurement can be made.

remainder of the R1 resistors, always
guarding pin 1.

To test the second R2 resistor, connect the

An example of the type of ohmmeter to be
utilized that incorporates a guarded measurement capability. It must be noted that
guarded measurements using ohmmeters
are satisfactory measurements up to a ratio
of about 10:1 between R1 and R2. Above
a 10:1 ratio, accuracy is degraded and
measurements can be incorrect because of
inadequate guarding capability of the
equipment.
Unguarded Resistance Measurements
In the case where no guarded ohmmeter is
available, the individual resistors can be
evaluated by comparing the unguarded
resistance measurement to the theoretical
value of the equivalent series-parallel
circuit and determining the percent of error
of each resistor.

Since the Dual Terminator circuit has many
resistors in parallel, a direct pin-to-pin
measurement for the values of R1 and R2
can be made using an ohmmeter with
guard capabilities.
The function of the guard pin is to apply and
equal voltage across the adjacent
(parallel) resistance path. When applied,
current flow is eliminated allowing an accurate measurement of the resistor under test.
Using the 8-pin SIP network shown, the
testing method would be as follows:
Test R1 Values
To test the first resistor, connect the ohmmeter measurement leads between pin 8
and 2. Connect the guard lead to pin 1.

Utilization of these formulas will enable you to determine the equivalent unguarded
resistance to be expected from any values of R1 and R2 for a Dual Terminator Network.

Termination Of The SCSI Bus
The Small Computer System Interface follows American
National Standard which provides the mechanical, electrical, and
functional requirements for an input/output bus to connect small
computers with a variety of peripheral devices. The most common application of this bus is to connect small computers with
disk drive (mass storage) units.
The primary resistor network application in SCSI busses is line
termination. The termination method is specified in ANSI
X3.131-1986 as either a Thevenin equivalent dual terminator

FIGURE 2.
In the single-ended configuration, the SCSI bus is defined for
lengths up to 6 meters, while the differential-line version provides for better commonmode noise immunity over cable
lengths up to 25 meters.
The signal assignments on the single-ended SCSI bus include
8 data lines, 1 parity line, and 9 control lines. Each of these 18
lines must be terminated, and it is convenient to do this using a
resistor network which contains all of the required resistors. An
additional 32 lines are ground or power lines which do not
require termination (there are 50 lines total in the cable). In a
similar fashion, the differential configuration of the SCSI bus
uses 18 pairs of lines, each requiring termination.
As of 1989, an extended version of the SCSI standard has
been in develop-ment by ANSI, called the SCSI-2 bus. This new
standard allows for 16-bit to 32-bit wide data transfers, while
also allowing a higher bit transfer rate.
Two cables are defined in the SCSI-2 bus, termed Cable A and
Cable B, where Cable B is optional (“wide SCSI” option). Cable
A is no different than the single cable used in the original SCSI
bus, and therefore uses the same number and types of resistive
terminators (i.e., dual terminators for single-ended and triple terminators for differential).
Cable B, however, is a 68-line cable, of which 29 lines (singleended) or 29 line-pairs (differential) require termination.
Application Guidelines
The principles of transmission-line theory apply to SCSI terminators, and therefore for proper operation their placement must
be restricted to the ends of the bus and nowhere else. This
implies that the terminators should be placed as close to the
SCSI devices as possible. It is permissible to place the terminator inside the SCSI device, but only if that device is located at
the end of the bus.
For disk drive applications, SCSI terminators must be present
on the host adapter card and at the disk drive end as well. Many
disk drive manufacturers have opted to design in removable
SCSI terminators into their units to account for the possibility
that their unit may not be the one at the end of the cable. For
these manufacturers, the combination of a resistor network in a
through-hole version plus a matching socket represents the only
(and expensive) alternative.
A final consideration is the cable itself. Since the terminators
are comprised of 220 ohm and 330 ohm resistors (single-ended),
the cable ideally should have a characteristic impedance which
328
matches the Thevenin equivalent of this resistor combination,
that is, 132 ohms. In the differential case, a characteristic impedance of 122 ohms would be ideal.
In addition, it is inadvisable to mix different, unmatched cables
in the same bus. Such a practice will result in undesirable signal
reflections which may compromise the integrity of the data transfer.

Use Bourns Networks To:
• Match impedance between memory driver and the DRAM
array.
• Minimize reflections and ringing in DRAM inputs.
• Prevent undershoot of RAS, CAS, and WE signals which
may result in latch-up of DRAM inputs
• Improve system performance by allowing faster setting
times for DRAM inputs.
Need For Damping
The address lines (RAS, CAS) and control lines (WE) of
dynamic RAM arrays are driven in parallel, causing significant
loading on the driver of the DRAM arrays. Each DRAM control
input (WE) has capacitive loading between 5pF to 7pF, while
each address line input has about a 10pF load.
Thus each DRAM input can be modeled as a transmission line
with distributed inductance and capacitance. If not properly terminated, signal reflections and ringing on the line will result,
adversely affecting the performance of the memory system. The
effects on signal transitions will be:
1. Increased settling time delay on low-to-high transitions.
2. Voltage undershoot on high-to-low transitions.

Increased settling time due to ringing reduces system performance because the design has to allow for the settling delay

voltage below 0 volts, can damage the driver IC as well as alter
the DRAM’s internal address register contents, causing potential
loss of data.

DRAM Applications
Application Guidelines
Termination of address and control lines is typically accomplished with low-valued resistors placed in series at the driver
output. Selection of the proper resistance value is performed in
two steps: approximation of the proper resistance using transmission line equations, and secondly, through trial and error,
changing the resistance value to account for real world deviations such as PCB vias and bends.
The appropriate transmission line equations are as
follows:
Zo = characteristic line impedance

ohms
0.8w + t
Td = propagation delay of the line

√0.475er + 0.67 ns/in.
Co = trace capacitance = 1000 (Td/Zo) pF/in.
Cd = equivalent trace capacitance associated with
each DRAM. It takes 0.5 inch to interconnect
one DRAM.
= 3.5pF/0.5 in. = 7 pF/in.
Zo’ = effective characteristic impedance, accounting
for capacitive loading of the DRAMs.
Zo
=
√1 + Cd/Co
Td’ = effective propagation delay, accounting for the
capacitive loading of the DRAMs
√
Td = Td 1 + Cd/Co
where er = relative dielectric constant of the PCB’s glass
epoxy layer
h
= distance from the trace to the ground plane
w
= width of trace
t
= thickness of trace
For example, for a trace with the following characteristics:
er
h
= 5 (for G10 glass epoxy)
w
= 15 mils
t
= 3 mils
= 30 mils
then, Zo = 85 ohms
Td = 0.15 ns/in.
Co = 1.76 pF/in.
Zo’ = 38 ohms
Td’ = 0.35 ns/in.
Thus on a theoretical basis, the design will require the resistance of 38 ohms to match the trace impedance of the PCB.
However, the actual impedance will differ from this theoretical
value due to the non-ideal characteristics of the PCB trace
geometry (i.e., bends, curves and vias in the trace), as well as
the manufacturing variations inherent in the components and
materials. Therefore, a trial-and-error process must be employed
in order to optimize the value of the damping resistor.
The procedure involves selecting various values around the
calculated value and observing the resulting waveforms on an
oscilloscope. Choose the value that best balances the reduction
in ringing/reflection and the reduction in speed: a large resistance value provides better damping, but will also add delay by
slowing the edge rate. Typically, resistance values for memory
damping will be in the range of 10 ohms to 50 ohms, with the
most common values in the 20 ohm to 30 ohm range.
Since memory damping is a type of series termination, distributed loading along the line will not be possible. That is, the
entire lumped load must be located at the end of the line, with
no other loads along the signal path. This will guarantee that the
waveform will remain undisturbed as it travels along the line. For
related reasons, the placement of the series damping resistor
should be as close to the driving device as possible.

Thin Film Applications
Thin film is the preferred generic description for the field of
micro-electronics in which conductive, resistive, and/or insulating films are deposited or sputtered on a ceramic or other insulating substrate. The films can be deposited either in a required
pattern or as a complete film layer and photoprocessed and
etched to form the required pattern.
The term “thin film” is derived from the fact that the deposited
films are of the order of a few micrometers in thickness compared with the 10 to 50 micrometers for thick film. Often, thin
film conductors are plated to improve conductivity.
Thin Film Applications
Thin film resistor networks typically find application in the analog world. The number one use of thin film is in controlling the
gain on operational amplifiers. Some other applications are as a
stable reference, stable voltage division, stable feedback loops
and analog to digital or digital to analog conversion. These networks may also be used for “wire-OR” pull-up, ECL output pulldown, TTL input pull-down, power down pull-up, open collector
pull-up, digital pulse squaring, current summing amplifiers, TTL
unused gate pull-up, TTL/MOS interfacing, coding and decoding, and telemetry.
Thin film resistors in a network form offer additional benefits in
performance. The resistors in a network are more closely
matched in resistance and TCR and actually see reduced differentials of temperature in the end use application. These combine to provide improved tracking in networks. This improved
tracking would be an advantage to the instrumentation and
industrial control markets.
Potential target markets for thin film include harsh environmental conditions as well as the need for precision resistors. The
improved ability to be stable at extended temperatures and the
increased ability to handle moist environments are both benefits
of the thin film offering. Target applications such as automotive
and telecommunications will benefit from these capabilities.
Thin Film Vs. Thick Film
The basic distinction between thick film and thin film is the
method of deposition of the metallization. In thick film, specially
formulated pastes are applied and fired onto a substrate. The
pastes are usually applied with a silk screen method and the
substrate is of 96% alumina ceramic. In thin film, a layer of metallization is sputtered onto a substrate and then a pattern is
etched into the previously applied metal layer, the substrates are
often 99.5% alumina ceramic, silicon, or glass. Thick film is an
additive process where layers of termination and resistor material are added to the substrate, while thin film is a subtractive
process where the unwanted material is etched away in a succession of selective photoetching processes. The use of photolithographic processes to form thin film patterns produce much
334
finer lines and traces than thick film processes. Thin film is very
appropriate for high density and high frequency applications.
Thick and thin film technologies are well suited for low to medium volume custom circuits. Thick film has the advantages of
lower cost (both of tooling up new designs and of production
runs), of being able to handle more power, and of being able to
service a higher range of ohmic values. Thin film has the advantages of tighter absolute and ratio tolerances and more environmentally stable components with lower noise and tighter TCR
than thick film.
Thin film technology is used wherever precision resistors are
needed.
Differential Op-amp Input
Differential Op Amps are needed in electrically dirty environments to reject noise transients that are picked up by wires. The
differential Op Amps subtracts the noise out of the two signal
wires.
Thin film tracking capabilities are needed in these circuits to
ensure that the input resistors do not affect the contents of the
incoming signal.

Thin Film Applications
Voltage Divider
Voltage dividers are used to step down voltages for analog
processing. Applications are found in multi-meters, oscilloscopes, oscillator stage of voltage control oscillators, etc. The

Data Conversion
Data converters are used to convert digital data to analog signals or vice versa. The precision of the high bit affects the overall precision of the data convertor. Thus, thick film resistors are
used in the lower bits while the thin film or bulk foil resistors are
used in the high order bits.

Soldering And Cleaning Processes
This application note is designed to provide step-by-step processing recommendations. It covers
the popular soldering process currently in use and provides recommendations and cautions for
each step. Since many variations of time, temperature, processes, cleaning agents and board
types in use, you will want to verify your own system. Bourns does not recommend the backside
mounting of passive components.
The process steps, recommendations and cautions are based on Bourns surveys of users, equipment manufacturers and materials suppliers. No warranty expressed or implied is made in regards
to the following recommendations.

Use the optimum
solder paste for the pattern,
printing process, and solder joint quality.
The adhesive must hold the
unit in correct orientation
upon placement and maintain the correct position
during any physical handling before the final soldering process.
Use pick-and-place equipment with a vacuum nozzle
ID that allows adequate
suction to pick the unit out
of the pocket cavity.
Heat/time cure should be
accomplished using either
an infrared radiation or a
convection oven.
Use the correct flux to
remove surface oxides,
prevent re-oxidation and
promote wetting.
RECOMMENDED
RECOMMENDED
RECOMMENDED
Cure using the temperature
profile specified by the adhesive manufacturer.
RMA (Rosin Mildly
Activated) flux or Halide
Free Water Soluble flux is
recommended.
RECOMMENDED
Typical solder paste alloy is
63Sn/37Pb. RMA,No-Clean
or Halide Free Water
Soluble fluxes should be
used.
RECOMMENDED
To assure positional stability, place a single dot of
epoxy under the unit.
Ensure nozzle inside diameter and vacuum levels are
adequate to maintain suction and part alignment.
CAUTION
CAUTION
Since solder paste usually
contains a high percentage
of activators, you must
ensure adequate cleaning
to remove all residues.
Consult your solder paste
supplier for cleaning methods. When cleaning additives are needed, only
those that are Halide Free
should be used.
Ensure parts are placed so
that all leads are centered
on the solder pads.
Epoxy
CAUTION
Use sufficient adhesive to
assure stability through the
cure process.
Avoid overflow of epoxy
onto solder pads and terminal areas.
Align the leads with the solder belt direction of travel
to avoid the part body creating a thermal shadowing
effect.
Excessive placement force
to the part should be avoided to minimize the risk of
package damage.
CAUTION
Use sufficient cure time to
ensure complete adhesive
transition from fluid to solid.
CAUTION
Avoid fluxes with Halide
activators.
Care should be taken to
assure the placed units are
not exposed to temperatures
in excess of the manufacturer's maximum.
Do not exceed the maximum
temperature rating of the
component.
Excessive curing before
placement may not allow
full seating of the part
causing incomplete solder
connections.
