7 - 1. Lead forming method
Avoid forming a lead pin with the lead pin base as
a fulcrum:be sure to hold a lead pin firmly when
forming. Lead pins should be formed before soldering
7 - 2. Notice of installation
7-Z-l installation on a P WB
!Jhen mounting an LED lamp on a PYBd, o not apply
physical stress to the lead pins.
. The lead pin pitch should match the PWBpin-hole
pitch:absolutely avoid widening or narrowing
the lead pins.
. lhen positioning an LED lamp,basically employ
an LED with tie-bar cut or use a spacer.
7-2-2 when an LED 1 is mounted directly on a PWB
If the bottom face of an LED lamp is mounted
directly on single-sided P’R the base of the
lead pins may be subjected to physical stress
Good
due to PWBwarp,cutting or clinching of lead
pins.Prior to use.be sure to check that no
disconnection inside of the resin or damageto
resin etc., is found. Whenan LED lamp is mounted
on a double-sided PW.the heat during soldering
affects the resin;therefore,keep the LED lamp
more that 1.6mmafloat above the P’JB.
7-2-3 Installation using a holder
During an LED lamp posiIioning,when a holder is
used,a holder should be designed not to subject
lead pins to any undue stress.
(Note)Pay attention to the thermal expansion coefficient
of the material used for the holder.Since the
holder expands and contracts due to preheat and
soldering heat, mechanical stress maybe applied to
the lead pins, resulting in disconnection.
7-2-4 Installation to the case
Do not fix part C with adhesives when fixed to the
case as shown in Figure..\ hole of the case should
be designed not to subject the inside of resin
to any undue stress.
