Teds post gave me an idea to solder in smt ic's using an idea similar to welding. Would it be possible to use a low voltage high current source to melt pre-tinned pads to the ic?The idea might be something like sticking a conductive bar over the pins of the ic and grounding the pads in some way. Hit a button and presto your ic is soldered.This shouldn't ruin the ic if there is no way the current can flow into the ic itself? I suppose though that this method isn't that good unless you can be sure there are no paths to ground through the ic... probably be pretty difficult in general?Just an idea.Jon

It sounds like a great way to destroy the chip, and maybe the PCboard's pads. It isn't that hard to hand solder small SMD packages.There are also "Dummy Components" and training boards available topractice on. They are used to teach hand soldering and rework in thereal world.-- Service to my country? Been there, Done that, and I've got my DD214 toprove it.Member of DAV #85.Michael A.

if the no two chip pins are to be soldered to electrically connected pins (or pins that are connected by some cdombination of components) then your idea could work. in general it's not going to work.
