Does anyone have any recommendations on parts that are more than 5 years
old for getting them to solder. You can see that parts reflow around the lead,
but when you take the part off of the pads there is no solder on the bottom
of the lead. These parts fail test, but then we add stronger flux and use hot
air to re reflow and the part passes. The leads are not bent, they are flush to
the board. We changed solder paste, which did help some, but not
completely. I would like to use the parts without having to send them out to
get the leads tinned before placement. These parts are obsolete so they are
hard to find parts. Any recommendations? Thanks for your input.
