Repairing IC pins

[Dwight K. Elvey]

Hi
 What kind of package are we talking about?
Plastic can be cut back by about 1/32" to allow connecting
a pin from a scrap IC. ceramic is a little tougher. If the
pin is one of those iron cored pins, you may not be able to
get deep enough to get a non-corroded surface to solder to.
 Even ceramics can be carefully solders to and a small amount
of hard epoxy applied to keep the strain off the solder joint
that will be quite small ( epoxy like JB Weld is hard most
clear epoxies are too flexible ).
 I have a number of RAM IC that are gradually failing because
they have the iron cored pins. I guess these were cheaper
but electrolysis between the plating and the iron rots them
out from the inside making the pin very fragile.
