PCB Washing No Clean

Electronics Forum | Fri Jun 24 12:32:06 EDT 2011 | ppcbs

I'm having problems with trying to get a good solder joint using a Ceramic PCB. We are using AMTECH hi-temp solder (ws-486 96.5/3.5ag). My profile looks great and I used the recommended profile from Amtech with a few adjustments. My max temp is about

We just tested AMTECH's LF4300 with good results. Excellent reflow/profiling capabilities, good processing. And decent cleaning. I say decent cleaning, because we did run into a small issue. While using Qualitek's LF paste, we experienced a lot o

Posting here because all the threads asking for feedback on it are locked. We have been extremely happy with the 4300 tacky flux for BGA attachment. Not only is it both washable and no-clean (i.e. wash-optional), it was also the only tacky flux tha

I received data sheets from a paste distributor in which Amtech gives a recipe how you can mix solder cream. They deliver the flux in plastic jars and the solderpowder in foil packages. You must mix the two components with a simple mixing tool. Has a

Steaming boards

Electronics Forum | Tue Apr 22 13:05:01 EDT 2003 | Mr. B

I am curious on some opinions on cleaning of boards. We have a board wash but after the wash we still need to stem them for better cleaniness. The timed steaming is prox. 2 mins a side and by the way this is a medical board. So if you got and suggest

Ni/Sn plated parts

Electronics Forum | Tue Jun 15 12:54:34 EDT 2004 | jsmith01

It seems like the break is happening between the sn and ni. The parts are dull in appearance will not take solder even with an iron after they come off so it leads me to believe that there is only ni left on the part. The parts are liquidous for ab
