Solder no closer than 3mm from the
DIP
SOLDERING
Bath temperature: 240
Immersion time: with 5 sec, 1 time
base of the package
Using soldering flux,” RESIN FLUX”
is recommended.
Attached data of temperatuare cure
for your reference
During soldering, take care not to
press the tip of iron against the
Soldering iron: 30W or smaller
lead.
SOLDERING
Temperature at tip of iron: 260 or lower (To prevent heat from being

Soldering time: within 5 sec.
transferred directly to the lead, hold
the lead with a pair of tweezers
while soldering
1) When soldering the lead of LED in a condition that the package is fixed with a panel (See Fig.1),
be careful not to stress the leads with iron tip.
2) When soldering wire to the lead, work with a Fig (See Fig.2) to avoid stressing the package.

" #$ " Regarding solution in the tinning oven for product-tinning, compound sub-solution made of tin &
copper and sliver is proposed with the temperature of Celsius 260. The proportion of the
alloyed solution is tin 95.5: copper 3.5: silver 0.5 by percentage. The time of tinning is constantly 3
seconds.

3) Similarly, when a jig is used to solder the LED to PC board, take care as much as possible to
avoid steering the leads (See Fig.3).

4) Repositioning after soldering should be avoided as much as possible. If inevitable, be sure to
preserve the soldering conditions with irons stated above: select a best-suited method that
assures the least stress to the LED.
5) Lead cutting after soldering should be performed only after the LED temperature has returned to
normal temperature.
1) The LEDs should be stored at 30 or less and 70% RH or less after being shipped from PARA
and the storage life limits are 3 months .
2) PARA LED lead frames are comprised of a stannum plated iron alloy. The silver surface may be
affected by environments which contain corrosive gases and so on. Please avoid conditions
which may cause the LEDs to corrode, tarnish or discolor. This corrosion or discoloration may
cause difficulty during soldering operations. It is recommended that the LEDs be used as soon
as possible.
Please avoid rapid transitions in ambient temperature, especially, in high humidity environments
where condensation can occur.

LED MOUNTING METHOD
3) When mounting the LED by using a case, as shown Fig.4, ensure that the mounting holds on
the PC board match the pitch of the leads correctly-tolerance of dimensions of the respective
components including the LED should be taken into account especially when designing the
case, PC board, etc. to prevent pitch misalignment between the leads and board holes, the
diameter of the board holes should be slightly larger than the size of the lead. Alternatively, the
shape of the holes should be made oval. (See Fig.4)
4) Use LEDs with stand-off (Fig.5) or the tube or spacer made of resin (Fig.6) to position the LEDs.

FORMED LEAD
1) The lead should be bent at a point located at least 2mm away from the package. Bending
should be performed with base fixed means of a jig or pliers (Fig.7)

2) Forming lead should be carried our prior to soldering and never during or after soldering.
3) Form the lead to ensure alignment between the leads and the hole on board, so that stress
against the LED is prevented. (Fig.8)
LEAD STRENGTH
1) Bend strength
Do not bend the lead more than twice. (Fig.9)

HEAT GENERATION
1) Thermal design of the end product is of paramount importance. Please consider the heat
generation of the LED when making the system design. The coefficient of temperature increase
per input electric power is affected by the thermal resistance of the circuit board and density of
LED placement on the board, as well as other components. It is necessary to avoid intense
heat generation and operate within the maximum ratings given in this specification.
The operating current should be decided after considering the ambient maximum temperature of
LEDs.
CHEMICAL RESISTANCE
1) Avoid exposure to chemicals as it may attack the LED surface and cause discoloration.
2) When washing is required, refer to the following table for the proper chemical to be sued.
(Immersion time: within 3 minutes at room temperature.)

NOTE: Influences of ultrasonic cleaning of the LED
and the way in which the LED is mounted.
Therefore, ultrasonic cleaning should only be
performed after confirming there is no problem by
conducting a test under practical.

OTHERS
1) Care must be taken to ensure that the reverse voltage will not exceed the absolute maximum
rating when using the LEDs with matrix drive.
2) Flashing lights have been known to cause discomfort in people; you can prevent this by taking
precautions during use. Also, people should be cautious when using equipment that has had
LEDs incorporated into it.
3) The LEDs described in this brochure are intended to be used for ordinary electronic equipment
(such as office equipment, communications equipment, measurement instruments and
household appliances). Consult PARA’s sales staff in advance for information on the
applications in which exceptional quality and reliability are required , particularly when the
failure or malfunction of the LEDs may directly jeopardize life or health (such as for airplanes,
aerospace, submersible repeaters, nuclear reactor control systems, automobiles, traffic control
equipment, life support systems and safety devices).
4) User shall not reverse engineer by disassembling or analysis of the LEDs without having prior
written consent from PARA. When defective LEDs are found, the User shall inform PARA
directly before disassembling or analysis.
5) The formal specifications must be exchanged and signed by both parties before large volume
purchase begins.
6) The appearance and specifications of the product may be modified for improvement without
notice.
