Hi Russ, I have a similar situation. I have been told that this can be caused by the nickel, over which the gold is plated, can result in suspect joints, embrittlement etc. Some joints can even be weak and broken without much force on some of my boa

I can understand that you really don't like a non-techie to post a reply/comment to the SMTNet forums. After all, it's always been about the technology/techs and not the sales folk. But what happens when a 'techie' provides incorrect or blatantly fa

Jim: Several points: 1 If you�re correct about corrosion of your component leads (which is entirely possible if the leads are steel, as you say), then the AIM 264-5 no-clean may not be aggressive enough to remove the corrosion you are seeing routin

Gold Immersion - Soft Joints

Electronics Forum | Mon Oct 25 14:48:29 EDT 1999 | William

All, I am having a problem with joints being soft after SMT. Especially 25 mil and smaller parts. It seems as though you can slide the leads right off of the solder. It takes only about 30-40 oz. of compression at 45 deg. to move leads off of join

| I need your help! We have been doing double sided surface mount for 4 years now. Up until 6 months ago I have not had a tombstoning problem. Since then I have a fairly high incidence rate of tombstones on the 0603 size resistors (no other parts).

| I am checking out trays for packing of Simms, and I would like to know what are the main differences between Anti-Static and Conductive trays. Anti-static are cheaper, but I would like to know about properties of one against the other, what are var

| We've recently encountered this problem where one of our .050" pitch BGA's were reflowing at the wave thus causing shorts... The board was profiled with probes stuck to a QFP solder joint, an 0603, and one of the BGA joints. There was an almost 7
