We've used them for several years now. They have done what they were purchased for and more. But, as time goes on, expectations of them rise, sales and marketing hype them as the ultimate cure-all of all defects, and then disappointment is experien

I am currently cleaning solder paste and adhesive stencils and misprinted substrates manually by using IPA, chem wipes, Q-tips, etc. Can you recommend a machine and chemistry that will clean all these applications?

Dear all: I need to know why do I find a lot of solder balles every where on the solder side of my assemblies after coming out of the wave solder machine. How can I avoid this? Thanks Hany

Not enough info, when you say no clean flux, is it for wave soldering process, please provide more detail, SMT or wave, is it all the joint which you find the void? Rgds

This happens to be after the water wash process. These are Burn-In boards so an SMT epoxy is used prior to wave. The flux used is Kester 2331ZX. Would using a thinner cause this to occur? The residue is all over the board. Thanks.

Hello All, Does anyone have any experience with soldering to vapor deposited metallizations such as gold? Or, does anyone know of any papers discussing soldering to vapor deposited metals? Any info would be greatly appreciated. Thanks, Glenn

In order to track the board flow through your line you will have to hook up all conveyor input sensors as well as the last output sensor to a PLC. You can program the PLC to provide an alarm signal if a accumulative time of xxx hours for any board is

Well Cal, we all had better be sales types. [Otherwise our bosses might question our reason d'entre, eh? My good looks only carry me so far.] I think as long as the sales types are adding content there is no reason to complain.

Can you increase the placement force on your P&P machine? It should squeeze the solder paste to all sides including the heel.
