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.

LED MOUNTING METHOD

1) 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)
