Hi! I have a very basic question about PCB cleaning. Which is the best way to clean the PCB after soldering? We use a lead free solder wire (3,5% flux inside the core) and after the soldering its a visible wetting,flux around the joint. When using th

I am seeing poor quality solder joints, mostly on 0402 components. The problem is that while the pad on the pcb is getting fully wetted, the solder is not flowing up the sides of the 0402 component, i.e. the 0402 lead is somewhat de-wetting. The re

Remember, even if you are successful in your justification of not cleaning your final product, there will always be a need for cleaning. Screens, stencils, misprinted PCBs, wave solder pallets, squeegees, tooling, etc. New cleaning applications can

I am looking for data / info on how flux may contaminate the solder in a Wave. I have a customer who requires a no clean process. Our wave is equipped with 2 separate fluxing systems and I would like to use OA in one and the No Clean in the other. Th

-Are these lint-free rags ESD-protected = yes, must be. I left that out thanks! -How do these lint-free rags remove the flux that seeps under components = no matter its a no-clean material and we are removing for esthestics only. -Have you considered

Now you are putting your assembly to vibrate with frequency of 30-60kHz. What kind of flux/paste are you using? If it is NC there is no reason to clean. If it is water wash, you should consider a proper way of cleaning it according to your paste/flux

Greetings All, Anybody out there experiencing white residues after cleaning? We currently use a batch cleaner to clean water soluble fluxes. this cleaner makes its own DI water by means of carbon and resin tanks. After cleaning there are residues

You are mixing long exposed paste back into fresh? How long has your fresh jar been open to the air? You are probably doing yourself a disservice by scavenging the paste (it could have moisture entrapped). Your visocity has definitely changed. You a
