PCD3330-1
As an output transducer for the ringer, a loudspeaker
(ringer out via tone output) or a PXE (ringer out via the
special ringer output which generates square wave ringer
tones with a peak-to-peak voltage of VDD to VSS) can be
used.
GENERAL DESCRIPTION
The PCD3330-1 is a mixed-mode multistandard repertory
dialler/ringer IC fabricated in a low threshold voltage
CMOS technology.
The (maximum 13) repertory numbers, redial and various
country specifications are stored in EEPROM so that
memory retention is guaranteed for 10 years without using
a battery back-up.
The operating supply voltage is 1.8 V (2.5 V in EEPROM
erase/write and DTMF and ringer mode) to 6.0 V with a low
current consumption in all operating modes: standby,
conversation, dialling, programming and ringer.
National telecommunications specifications can be fulfilled
by changing a few bytes in EEPROM which contain the
different telephone timing and dialling procedures.
The two on-chip tone generators are used for Dual Tone
Multi-Frequency (DTMF) dialling, and for generating a
melody during ringing, which is activated when a correct
incoming ringer frequency is detected.

network). When the RESET input becomes HIGH it
initializes the IC.
FUNCTIONAL DESCRIPTION
5.1
5.1.1
Inputs/Outputs
The RESET-pin should not be left open (not-connected) in
any circumstances.
COL1 TO COL6, KEYBOARD INPUTS
The sense column inputs COL1 to COL6 and the scanning
row outputs ROW1 to ROW6 can be directly connected to
several keyboard layouts, up to a maximum 6 × 6 single
contact keyboard matrix.
5.1.6
As chip enable input (active HIGH) it is used to initialize
part of the system, to switch from standby to the ringer or
conversation, programming or dialling mode and to detect
line breaks.
DMO, DIAL MODE OUTPUT
As ringer-frequency input it measures the time between
two LOW-to-HIGH transitions, thus measuring the ringer
frequency.
This output is HIGH during the make and break times in
pulse dial mode. Its function is to lower the DC line voltage
during these pulses.
5.1.7
This output is LOW during DTMF dialling, during the
inter-digit-pause in pulse dial mode and during
conversation mode.
5.1.3
HOOK, ON/OFF HOOK DETECTION INPUT
5.1.8
MUTE, MUTE OUTPUT
The MUTE output is used during dialling. In the
PCD3330-1 the MUTE output has four different selectable
options:
If CE = HIGH and HOOK = LOW the PCD3330-1 is in the
ringer mode.
• M1, normally LOW, but HIGH during inter-digit-pause
and make/break in pulse dial mode, during tone-on and
tone-off in DTMF mode, and during flash or earth
XTAL1 AND XTAL2, OSCILLATOR INPUT/OUTPUT
• M1, the inverted signal of M1
Time base for the PCD3330-1 is a crystal-controlled
on-chip oscillator which is completed by connecting a
3.579545 MHz crystal or ceramic resonator (PXE)
between XTAL1 and XTAL2. The XTAL2 is the oscillator
output and can be used as driver for another oscillator
input. A low-cost quartz crystal from Philips (code number.
4322 143 04401) is available, specially for telephony
applications.
The oscillator starts when VDD reaches the operating
voltage level and CE = HIGH.
5.1.5
ROW1 TO ROW6, KEYBOARD OUTPUTS
The scanning row outputs ROW1 to ROW6 and the sense
column inputs COL1 to COL6 can directly be connected to
several keyboard layouts (max. a 6 × 6 single contact
keyboard matrix).
If inputs CE and HOOK are both HIGH then the
conversation, programming or dialling mode is selected.
Switching the HOOK input LOW longer than the
reset-delay-time results in switching to the standby mode.
5.1.4
CE/RF, CHIP ENABLE AND RINGER-FREQUENCY
DETECT INPUT
Four of the sense columns are used to store the contents
of the EEPROM in the factory (see Section 5.3).
5.1.2
PCD3330-1
• M2, normally LOW, HIGH during make/break in pulse
dial mode, during tone-on in DTMF mode, and during
flash or earth
• M2, the inverted signal of M2.
Each time the M-key on the keyboard is pressed the MUTE
output goes to its inverted state.
5.1.9
RTO, RINGER TONE OUTPUT
This is the special ringer output. When this output is
selected the output of the internal tone generators is not
connected to the TONE output but to this RTO output.
The ringer output signal has a peak to peak square output
voltage of VDD − VSS (this is used with a PXE transducer).
RESET, RESET INPUT
When the RESET pin is connected to VSS, a reset is
generated by an internal power-on-reset circuit, which
produces an internal reset pulse every time that the supply
voltage VDD crosses the power-on-reset voltage level
(typ. 2.0 V).
5.1.10
DP/FL, PULSE DIALLING AND REGISTER RECALL
OUTPUT
Depending on the application it can be necessary to
generate a reset via an external circuit (e.g. an external RC

microphone mute which is controlled by the M-key.
After off-hook this output is HIGH and will toggle by every
press off the M-key.
It pulses a calibrated FLASH or register recall pulse
(if selected) when the keyboard input FLASH is pressed.
5.1.11
VDD AND VSS
5.1.15
VDD and VSS are the supply terminals.
5.1.12
It pulses a calibrated EARTH pulse (if selected) when the
keyboard input FLASH is pressed.

• Figure 2. The simplest keyboard. All basic functions are
available but only 2-key abbreviated dialling
(MEM + digit) is possible.
PD/DTMF, PULSE/TONE MODE SELECTION
• Figure 3. As Fig.2 but with 3 extra 1-key abbreviated
dialling keys.
To select the dialling mode, this input PD/DTMF must be
connected to VDD or VSS.
• Figure 4. As Fig.2 but the 10 repertory numbers can be
reached via M0 to M9 with 1-key abbreviated dialling.
PD/DTMF = HIGH (VDD) = DTMF mode.
PD/DTMF = LOW (VSS) = pulse mode.
• Figure 5. The most complex keyboard. A second
possibility for column 4 exists. This column can be
selected via EEPROM.
The PCD3330-1 accept the information also during
manual dialling. Switching the input to pin PD/DTMF
changes the dialling mode after finishing the digit in
progress.
Keyboard entries are valid 20 ms (debounce time) after
the leading edge of a keyboard entry.
RVOL1 AND RVOL2/LSE, RINGER VOLUME
OUTPUTS
The RVOL1 and RVOL2 outputs can be used to control the
ringer output volume in four steps. The volume can be
changed via keyboard during ringing or conversation
mode (off-hook). The selected output level is stored in
EEPROM.
During on-hook dialling the RVOL2 output becomes the
LSE output for switching the listening-in amplifier.
When the on-hook dialling option is not selected and the
microphone mute option is active output LSE change to a
1997 Jan 15
Keyboard
The PCD3330-1 is programmed to work with various
keyboards which can be connected to the sense column
inputs COL1 to COL6 and the scanning row outputs
ROW1 to ROW6. In this specification four examples are
given:
In ringer mode this TONE output can be used for
generating the ringer output tones. Whether this TONE
output or the special RTO (ringer tone) output is used is
selected via EEPROM.
5.1.14
EARTH, a/b LINE TO EARTH CONNECTION
The EARTH output drives an external switching transistor.
which connects the a- or b-line to earth.
TONE, DTMF OR RINGER TONE OUTPUT
In DTMF dialling mode the dual tones which are provided
at the output TONE are filtered by an on-chip switched
capacitor filter, followed by an active RC low-pass filter.
Therefore, the total harmonic distortion of the DTMF tones
fulfils the CEPT recommendations. An on-chip reference
voltage provides output tone levels independent of supply
voltages. The impedance is 100 Ω typically.

EEPROM PROGRAMMING PROCEDURES
The PCD3330-1 supports four EEPROM programming procedures:
1. LNR is described in Section 5.6.2
2. Repertory numbers is described in Section 5.6.9
3. Via pins 1 to 4 (COL1 to COL4)
4. Via keyboard (can be locked with the Program Blocking byte).
Method 3 is normally used by the setmaker before the set leaves his factory.
Method 4 is most suited for usage in the field (e.g. the shop where the set is purchased).

5.3.2.1
Factory EEPROM programming procedure
5.3.2.2
The COL1 to COL4 of the PCD3330-1 can be used in the
factory to read or write the contents of the internal
EEPROM. COL1 (pin 1) is the SCL and COL2 (pin 2) is the
SDA of the I2C-bus interface, while COL3 (pin 3) and
COL4 (pin 4) determine the mode selected. In Fig.6 the
principle for this programming procedure is given.
PCD3330-1
EEPROM programming procedures via
keyboard
This procedure is only active if EEPROM Program
Blocking byte (number 127 of the internal EEPROM) is
set to ‘FF’ hex. If this byte is ‘00’ hex it is not possible to do
the program procedures described in this chapter.
Byte 127 of the EEPROM can only be set by the factory
EEPROM programming procedure.
In the field all telephone options can be changed easily by
a special program procedure:

Change the mark-to-space ratio from 3 : 2 to 2 : 1. Then
bit 2 of EEPROM byte-120 has to be changed from 0 to 1.
The necessary action is as follows:
If during the programming mode S1 is opened the
programming stops and the PCD3330-1 goes to the
telephone mode. If now S1 is closed again the set stays in
telephone mode.
• Depress the STO-key
• Depress the LNR-key
• Depress the 1-key (first digit access code)
In the write mode the PCD3330-1 is able to read the
contents of an external RAM (128 bytes) or the PCF8581
(EEPROM) via COL1 and COL2.
• Depress the 6-key (second digit access code
• Depress the 0-key (third digit access code)
• Depress the LNR-key again (end the access code)
In the read mode the PCD3330-1 sends the contents of its
internal EEPROM via COL1 and COL2 to the external
device.
• Press the 0-key (last digit of EEPROM byte-120 is the 0)
• Press the 2-key (bit 2 has to be changed)
• Press the 1 (changes the mark-to-space ratio to 2 : 1)
All 128 bytes of EEPROM are read or written in each read

PCD3330-1
Pulse/DTMF dialling function
PULSE/DTMF MODE SELECTION BY PIN
5.5.1
The PCD3330-1 has two dialling modes, pulse dialling and
Dual Tone Multi Frequency (DTMF). These can be
selected via the PD/DTMF input in the following way:
Operation mode overview
The PCD3330-1 has in total five operation modes:
standby, conversation, ringer, dialling and programming.
The state diagram is given in Fig.7.
PD/DTMF = HIGH (VDD) = DTMF mode.
PD/DTMF = LOW (VSS) = pulse mode.
When both CE/RF and the HOOK input are LOW the
PCD3330-1 goes to the standby mode, in which the
contents of the redial register is refreshed, the oscillator
switched off and the device enters the low current state.
The controller accepts the information also during manual
dialling. Switching the input to the pin PD/DTMF changes
the dialling mode after transmitting the digit in progress.
A HIGH state on the CE/RF and/or the HOOK input will
cause a complete initialization of the PCD3330-1 which
means setting of the I/O pins, clearing of the RAM and
reloading the EEPROM contents into it.

PCD3330-1
Output MUTE has several programmable options, MUTE
can be configured as M1, M1, M2 and M2. In Fig.8 the
timing diagram of these output possibilities is given.
After completion of the number string the circuit changes
from dialling mode to conversation mode.
PULSE DIALLING (PD/DTMF = LOW)
The keyboard entry initiates a recall of a previously stored
number or is a simultaneous keying-in and pulsing-out
activity, with storing for possible later recall. If in the
recalled number or at keying-in the keys A,B,C or D
(options A to D keys selected) are used these digits are
not transmitted.
If at keying-in the keys ∗ or # are used this results in a
switch over to DTMF dialling. Normally, keying in is faster
than pulsing-out (fed from the redial register). Pulse
sequences start with an inter-digit pause of 840 ms
duration, followed by a sequence of pulses corresponding
to the present digit in store. Each pulse starts with a mark
(line break) followed by space (line make).
The pulse period is 100 ms with a mark-to-space ratio of
3 : 2 or 2 : 1 (mark-to-space ratio selection). After
transmission of a digit, the next digit is processed, again
starting with an inter-digit pause. The pulses are available
at the DP/FL output and can be used to drive an external
switching transistor in pulse dialling mode.
The transmission IC is put in the dialling mode by means
of output MUTE.
DUAL TONE MULTI FREQUENCY (DTMF) DIALLING
(PD/DTMF = HIGH)
5.5.3
The PCD3330-1 converts keyboard inputs into data for the
on-chip DTMF generator. Tones are transmitted via output
TONE with six programmable minimum tone burst/pause
durations of 60/90, 70/70, 80/80, 100/100,
100/140 or 140/140 ms. The maximum tone burst duration
is equal to the key depression time. With redial and
repertory dialling tones are automatically fed at the
programmed rate. Again the MUTE output has several
programmable options namely, M1, M1, M2 and M2.
In Fig.9 the timing diagram of these output possibilities is
given.

If the FLASH function is selected a calibrated FLASH pulse
(recall register) is generated on the DP/FL output and the
MUTE output is active.
The calibrated FLASH time is programmed for 100, 115,
270 or 600 ms in EEPROM.
DTMF DIALLING IN PULSE DIALLING MODE (MIXED
MODE DIALLING)
If the controller is set to the pulse dial mode (pin PD/DTMF
is LOW), activation of keys TONE, ∗ or # changes the
dialling mode to DTMF.
Its entry is stored in the redial register and it generates
automatically an access pause, after which the following
digits are transmitted in the DTMF mode.
The digits entered after keys TONE, ∗ or # are not
transmitted in the redial mode. The TONE key is never
transmitted in the redial mode.
The TONE key is never transmitted, whether ∗ or # are
transmitted depends on the selected option.
A second touch of the TONE key is ignored. The ∗ or #
keys pressed after a switch over to DTMF dialling are all
transmitted.
If the EARTH (‘Connect a/b to earth’) function is selected,
the EARTH output becomes HIGH and the MUTE output
is active. The time of earth connection is 400 ms.
When the FLASH key is pressed the telephone number
entered before the FLASH key is stored in the redial
register (EEPROM).
• After dialling 1 - 2 - 3 - ’FLASH’ - on-hook Redial is
1-2-3
• After dialling 1 - 2 - 3 - ‘FLASH’ - 4 - 5 - 6 - on-hook
Redial is 4 - 5 - 6.
If the controller is initially set to the DTMF mode (pin
PD/DTMF is HIGH), activation of TONE is ignored and the
∗ or # are stored in the redial register and transmitted in
DTMF mode.
5.5.5
5.5.6
This DIS (disconnect) key is only available if the function
key option is programmed. Touching the DIS key activates
output DP/FL for 800 ms. In this case the telephone set
turns to the ON-HOOK state for this calibrated time, after
which it comes back to the OFF-HOOK mode.
FLASH OR EARTH FUNCTION
Whether the Flash or Earth function is activated by the
FLASH key is programmed in the EEPROM.

5.5.7
Up to 24 digits can be stored in the redial register. After the
work register overflows, a 10 digits First-In-First-Out
register (FIFO) takes over as buffer and the contents of the
work register is now copied to the redial register.
After transmitting the first digit of the FIFO register this
position is automatically cleared to provide space for the
storage of new data. In this way, the total number that can
be transmitted is unlimited, provided the key-in rate is not
excessive. However, if the FIFO register overflows (more
than 10 digits in store) further input is ignored.
MUTE FUNCTION (M-KEY)
When no dialling or programming is active, every time this
M-key is pressed the MUTE output goes to the active or
inactive state depending on its previous status.
When the MUTE output is in the active state and another
key is pressed then the MUTE output is switched back to
the inactive state.
When there is the on-hook dialling is not selected and the
Microphone mute flag in EEPROM is HIGH, every press
off the M-key will result in the inverted value of the
RVOL2/LSE output. At off-hook the status of this output is
HIGH.
5.5.8
Input digits are transmitted immediately with minimum
transmission time. Transmission continues for as long as
digits are input.
ON-HOOK DIALLING CONTROL
5.6.2
If required, the on-hook dialling control feature can be
selected by programming the corresponding bit in
EEPROM.
When this on-hook dialling feature is selected, the power
supply to the PCD3330-1 must be maintained during
on-hook.
The LNR key can be used in two other ways, known as the
‘cursor’ method and the ‘Atlanta’ procedure, to allow
external numbers to be redialled from a PABX with an
appropriate access pause.
5.6.3
When the handset is off-hook (not on the cradle) activation
of this HOOK-key switches the loudspeaker on
(LSE = HIGH) or off (LSE = LOW) (listening-in feature).
This ‘cursor’ method allows an access code to be entered
and access confirmation tone to be received before an
external number is redialled.
Number storage, transmission and redial
5.6.4
NUMBER STORAGE AND TRANSMISSION
ACCESS PAUSE BY ATLANTA PROCEDURE
If the first key entered is the redial key, but this key is kept
down, then only the first digit held in the redial register is
transmitted. After releasing the redial key the remaining
digits held in the redial register are dialled.
If the first key pressed at off-hook is 0 to 9 in pulse dialling
or 0 to 9, ∗ and # in DTMF dialling mode, digits are entered
into the work register and compared with the previous
entries stored in the redial register. As long as the newly
dialled digits are equal to those stored, the contents of the
redial register are unaffected.
The ‘Atlanta’ procedure allows a single stored access digit
to be transmitted, but redial of the external number to be
delayed until access has been confirmed.
When the newly pressed digit is different from the one
stored in the redial register the contents of the work
register are copied to the redial register when going
on-hook (or every other action equal to on-hook).
1997 Jan 15
ACCESS PAUSE BY CURSOR METHOD
If the first key entered is not LNR but numerical digits,
these digits are compared to those held in store. As long
as the digits entered equal those stored, the redial register
in not cleared and dialling can be continued by pressing
the redial key. The already dialled part is not redialled.
Redial is inhibited as soon an entry is unequal to the digit
at the same position held in store.
When during on-hook dialling the handset is lifted from the
cradle the on-hook dialling mode is switched off and the
LSE output is set to the active (LOW) state.
5.6.1
LAST NUMBER REDIAL (1 TO 24 DIGITS)
If the first key pressed and released is LNR, the stored
number in the redial register is recalled and transmitted
immediately.
In telephone sets developed for on-hook dialling
(an electronic hook-switch must be present) activation of
the HOOK-key during on-hook results in an off-hook via
the DP/FL output, and the LSE output becomes HIGH.
As long as the handset stays on the cradle a new
activation of the HOOK-key results in an on-hook, and the
LSE output becomes LOW.
5.6
PCD3330-1
5.6.5
10-NUMBER REPERTORY DIALLING
The PCD3330-1 includes a 10-number repertory dialler,
16 or 20 digits each, which is accessible with a one or
two-key procedure.
18
Philips Semiconductors
Product specification
Multistandard repertory dialler/ringer with
EEPROM
The maximum length of these repertory numbers is
16 digits including the manually stored access pauses.
The chain dialling procedure is equal to that explained in
10-number repertory dialling.
The 10 repertory numbers can be recalled with the
M0 to M9 keys or by pressing the MEM key followed by a
numeric digit from 0 to 9.
If the keyboard matrix contains the keys M0 to M9, each of
the 10 repertory numbers can be recalled using the
corresponding single key.
If the keyboard matrix contains the MEM key each of the
10 repertory numbers can be recalled by depressing MEM
followed by the numeric digit 0 to 9.
5.6.7
5.6.8
Chain dialling
For pulse dialling 1.5, 2.5, 3.0 or 6.0 s (inter-digit pause not
included).
For DTMF dialling 1.0,1.5, 3.5 or 6.0 s (inter-digit pause
not included).
5.6.9
STORING REPERTORY NUMBERS
When the Keytone active bit in EEPROM is HIGH, every
key activation in programming mode will result in a keytone
of 1046 Hz lasting 200 ms.
The store mode starts after going off-hook and depressing
the STO-key. With the PCD3330-1 a selection can be
made between two store modes, the ‘General’ and the
‘German’.
3-NUMBER REPERTORY DIALLING
When the repertory length programmed in EEPROM is set
to 16 digits, the PCD3330-1 includes also an additional
3-number repertory dialler.
These repertory numbers are only accessible with the
one-key procedure.
Repertory numbers can be stored into EEPROM via the
one-key access or the two-key access method and
following the German or General storing procedures. This
is detailed in Tables 5 and 6.
These 3 repertory numbers can only be recalled with the
E-1 to E-3 keys.
Table 5
MANUAL ACCESS PAUSES
The AP-key is used to insert an access pause during
manual dialling. It is possible to select between four
possible access pause times for each dialling mode:
Repertory numbers can be dialled-out after or before
entering manual dialling or last number redial and by
entering the memory locations in successive order (‘chain
dialling’).
During transmission of a number recalled from the
memory location, the controller does not accept keyboard
entries. Dialling can be continued as soon as the number
under transmission is completed.
Note that the last memory location which is transmitted is
stored in the redial register.
5.6.6
ACCESS PAUSE STORAGE
If during entering a telephone number via keyboard for
normal dialling or during repertory number programming
the AP-key (access pause key) is pressed, then an access
pause is stored in the redial or repertory dial register.
The maximum length of these repertory numbers is
16 or 20 digits (depending on the programmed repertory
number length) including the manually stored access
pauses.

RINGER OUTPUT PIN SELECTION
5.7.4
RINGER VOLUME CHANGE DURING CONVERSATION
AND RINGER MODE
The ringer signal is sent via the special Ringer Tone
Output (RTO) or via the TONE output depending on the
option selected.
When a loudspeaker is used as a transducer, it is better to
use the TONE output. One of the internal tone generators
directly supplies this output with VRMS = 181 mV.
The RTO output signal, used for PXE transducers, is a
block with a peak-to-peak output voltage of VDD − VSS.
5.7.2
PCD3330-1
The ringer volume can be controlled by the port pins
RVOL1 and RVOL2 and its value is stored in EEPROM.
The output volume can be changed:
• Via the EEPROM programming procedure (see
Section 5.3.2)
• During conversation mode, when the function keys
option is chosen, with a special key sequence
RINGER INPUT FREQUENCY MEASUREMENT
• During active ringer by a simple key press.
The melody ringer becomes active for all incoming ringer
frequencies higher then the ringer detection LOW
frequency and lower then the ringer detection HIGH
frequency supplied to the CE/RT input of the PCD3330-1.
The ringer detection LOW and ringer detection HIGH
frequencies are selected such that it is possible to use this
PCD3330-1 for both single and double phase rectifier
applications. It is possible to select one out of four ringer
detection LOW and four ringer detection HIGH frequencies
options which are given below:
In Conversation mode the procedure is as follows:
• Put the set in conversation mode (supply necessary)
• Depress PR (ringer program key)
• Press one of the four acceptable volume keys (1 to 4);
see Table 8.

CONVERSATION AND RINGER MODE
During active ringing the PR key is not used, the procedure
is as follows:
The generated melody is built up out of three frequencies.
These frequencies are generated successively in a
selected repeat frequency.
There are four steps and they can be changed:
• Active the ringer (only then this repetition rate correction
is possible)
• Press one of the four acceptable repeat frequency keys
(9, ∗, 0 or #) see Table 11.
• Via the EEPROM programming procedure (See

Multistandard repertory dialler/ringer with

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
11 SOLDERING
11.1
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
11.3.2
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
11.2
11.2.1
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
DIP
SOLDERING BY DIPPING OR BY WAVE
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
• The package footprint must incorporate solder thieves at
the downstream end.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (Tstg max). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.
REPAIRING SOLDERED JOINTS
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
11.3
11.3.1
11.3.3
REPAIRING SOLDERED JOINTS
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
SO
REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO
packages.
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
1997 Jan 15
WAVE SOLDERING
Wave soldering techniques can be used for all SO
packages if the following conditions are observed:
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
