A PCBA contains a couple of parts that are not sealed and can't be water washed. We hand solder these with no-clean after everything else is water washed. The designer says the no-clean residue must be completely removed so that it will not affect

Hi, Walter, Why don't you try no-clean flux? We ever met the same condition, later, we changed to no-clean flux solved the problem.

Yes, no-clean is more of a challenge, particularly for halide-free no-clean. Requirement on probe testability will make it more difficult.

KRIKIES, a designer insisting on cleaning no-clean residues! the BLAME-THE-PROCESS bandwagon travels everywhere, me lad!

Get the ionic specs from your flux manufacturer, and show it to the designer. No-clean flux/solder is supposed to be low to minimal in ionic contamination, which allow the whole no-clean thing. If he needs further proof, you can have the board io

Hello Dr. Lee, Will no-clean fluxes be more of a challenge to develop?

I don't know the name of the flux. but is a no-clean solder paste.

Im using Hi-Grade 1075 now. Is the 3541 a no-clean?

The low solids flux that is commonly called no-clean can affect some circuits. We are building a PCB that measures pico amps. The customer required that it be cleaned. We would rather used the low solids and eliminate a step. The customer had

Yer not making this easy. What kind of flux? If no-clean flux, what controls are you using to assure you are: * Applying the correct amount of flux? * Properly activating the flux? If water washable flux, talk to us about your cleaning methods and
