Solderability
After dipping the terminals to a depth of
approximately 3 mm from the body in a
soldering bath of 235°C for 5 seconds, the
terminals shall be visually examined.
The inspection shall
be carried out under
adequate light with
normal eyesight or
with the assistance
of a magnifier
capable of giving a
magnification of 4
times to 10 times.
The dipped surface
shall be covered
with a smooth and
bright solder coating
with no more than
small amounts of
scattered
imperfections such
as pinholes or un-
wetted or de-wetted
areas. These
imperfections shall
not be concentrated
in one area.
