TechNetters,
I'm looking at a what seems to me like a good sized piece of 303 stainless steel, plated with nickel-tin, a standoff about 7 mm in diameter, 6 mm long, with a wall thickness of about 1 mm. Using a metcal iron, our folks are having trouble soldering this to a PC board. One of the quality inspectors says there has not been a problem in the past, with this part, using the metcal iron. The standoffs have been in stock for 1 year after nickel-tin plating.
Here are two questions I think of:
(1) Is 1 year beyond the shelf life of nickel-tin plating? Operators think there is a "coating" on the standoffs that inhibits soldering.
(2) Any ideas about a preferred soldering technique for a part like this?
Thanks for any feedback. All production supervisors are out for the day, so QA is trying to handle this one...Lou Hart Compunetix
