Part is most likely a QFN package. IPC-610-D has standards on solder quality for this new type of package.

Wasn't trying to be funny. 90% of the time when I hear the wave is doing ???????? "we are sure that it is not like that before" I check and the parts are tilted or whatever before the wave. I had some more suggestions and ideas but..........

Q: Is anyone aware of any solderability issues that may exist when soldering beryllium copper parts (in this case spring contacts) to a PCB using standard Pb63/Sn37 solder paste/wire?

Paste is eutectic and it's copper based parts. Just another observation, i notice that the "flux" between the bottom foot and solidified paste is still in gluey state. Observation on good reflowed leads showed brittle type of flux residue. Can anyone

Larry...LISTEN ! : From my experience you are asking for trouble by thinkin what ur thinkin. The scary part is that you probably supply plasma arc accumulator boards for NASA.

Spare parts? Like what? If it's your belt motor, try cleaning out the gear box attached to it. 99% of the time it's the lube in this gear box that dries out and turns to glue.

Kevslatvin When you visit the machine suppliers, why don't you time the setup of your 25 reels of components as part of your assessment?

They work okay, better than no leader tape. Of course to attach you may throw a couple of parts away as well. What you really need to do is discontinue buying strips.

The leader tape from Sierra works good for us. But if you have to work only with small strips and you can't affort to lose any parts think of moving them into waffle packs. It depends though if your machine has a tray for that. Regards, Cristina

maybe i'm missing something, i though copper dissolution is a major concern when reworking parts from a lead free process, whats the forums opinion?
