Steam Cleaning for flux

Electronics Forum | Mon Feb 22 22:25:19 EST 2021 | rowan

Hi, We were having flux residue entrapment under the component. So we are evaluating to add steam cleaning with DI water, using precision micro prior to Di wash. Have anyone tried this and what are pros and cons. Your advice appreciated. Thanks

What size discrete components and have you evaluated your pad geometries? If pads are too far apart this will happen. The flux resudue is simply there because you didn't solder the component. It will stay on top of the solder bump. You can see this

Hi, I could like to find out what are the things need to look out if I'm doing a new SMT solder paste ( water soluble & no-clean ) evaluation. And also flux ( spray type ) for wave-solder ( water soluble & no-clean ). Appreciate for all the input..

We use the exact same method Chunks outlined for evaluating just about anything we're going to roll out worldwide, whether it's a material or a machine. List your factors (print speed, solder spread, etc), assign each a weight, evaluate each paste a
