I'd agree with getting a stencil fully cut, and taping the pads you don't want paste on. But, I'd also check with the people that will be doing the hand soldering to see what they prefer. Some people prefer soldering on bare pads, some prefer solde

We've used glass (pyrex, corningware) bread pans in the past, not filling them much over 1" deep. It takes a while but leaves solder ingots sized well to drop back in. Have not tried lead free yet, the higher temp could be an issue using same ty

Guys, If there are any specifications or ciriterions for solder paste deposition thickness and volume evaluation. For example, QFP (0.5 mm pitch), 6~8 mils, 3000 mil^3 PLCC: 8~10 mils, ... . . Thanks in advance. Best Regards,

Yeah, but when the operator drops regular solder bars into your lead-free pot, does that mean I should paint my bars, too?

The concern about lead contamination of lead-free solder has to with zone refining. For more, look here: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=30315

Hi Stephen, it seems they call it differently . What they need is an insruction data they can import to the machine, how the IC is soldered, the relative orientation for some parts,ect.

Besides, regulated power supply should be installed separately on the printing boards. When power and circuits share the same printing boards, it should be avoided that regulated power supply and circuit components are mixed or power and circuits sha
