Hi guys. I'm hoping maybe some of you can help me with some information today. I'm looking to find out "ballpark" how much a decent board washer would set me back. The one I currently have just isn't doing the job the way I want it. It seems to have

What low profile components are you dealing with? We have had problems with cleaning under leadless chip carriers using an aquastorm 200 with Kyzen Aquanox 4520T and the general concensus is that you will not clean under this type of device with an

Can be done with AquaStorm 200, with some mods. I worked on a project a few years ago for a military company that needed to clean no-clean solderpaste residues from under LCC devices, we're talking like 2mil standoff. We ended up using a Zestron clea

As we understand it, you: * Get some nice BGA from your supplier * Find BGA to be packaged properly * Bake the BGA for 24 hours at [what temperature?] to reduce the potntial for damaging moisture sensitive components during following processes * Remo

We are going to start doing rework of Lead Free BGA's. Have always used flux for SN/Pb boards/BGA's with good results. Can flux be used fro lead free as well? Boards were originally assembled using lead free paste and components. Hence, the BGA w

Hi Ronald, We have both, 2x calrod on our leaded delta and calrod/convection on our leadfree, both are IR in 3th zone. Indeed, the forced convection is way more efficient, we can run it at 100deg C, where we would need 300deg C for the calrod for t

I'm just looking for some fire-power here. We have a board that when it goes through reflow the first time, everything is fine and has good wetting. When we do the secondary side, one specific part is then Dewetting according to our production oper

See if the solder is leaving the pad(s) and is wicking up the component. This is long shot but I have seen something similar to this possibly in a wave process. We had a very thin board and a very large QFP on top. During wave operation the solder

We never run raw solder paste through our board cleaner, because: * Flux floats on the water in the tank and contaminates everything, including the boards being 'cleaned'. [Prove this to yourself by observing the location of gray schmutz on the insid
