Our facility helps customers clean no-clean soldered boards on a regular basis, and it definitely can be done but is a little more challenging than boards built with water soluble flux - one piece of advice I would give is to use low water pressure (

If I had to deal with this problem, I would switch to water soluble paste. It is a much more cost effective solution.

| Hi all, | | We have a little discussion here about the suitable flux for a certain process, as all of us are beginners we need your advice. | | We are producing VGA cards and mother boards for PC's all components to be wave soldered are TH, the S

DO NOT Mix Technologies.... If you are using a no clean solder paste use a no clean wave solder process. I have direct experience with using a no clean paste and a RA water-soluble wave solder process. When cleaning with the water wash system your

Dear JSK, It sounds like the root causes of your problem are two fold. First, excessive heat will polymerize the abietic acid found in rosin forming neo-abietic diamers and polymers which are much less soluble than the parent monomer. There are

Sorry to disappoint. No-Clean fluxes are resin-based. They are not soluble in water. Water soluble fluxes are by nature Organic Acid and are soluble in water AND must be cleaned within a short period after reflow as they remain conductive and corrosi

I know you mentioned you use a Tech Spray product. We have had success with their "Wondermask" water soluble product. When using a chemical additive (saponifier) in an aqueous cleaning system we have not experienced residues. I hope that helps. https

Our company uses a conveyorised aqueous cleaner to wash printed circuits after water soluble solder paste is reflowed. The system is closed loop with carbon and resin filters. The water eventually will get dirty. Can it be dumped? Treated? How do y

I agree but, are there really heavy metals in this water? Our process is as follows. Print Paste Reflow Board (no components, water soluble paste only) Wash Board Same reflow profile for almost every order so no solder balling issues etc. Carbon an

Jake, The No-cleans on the market, to me, still aren't as good as OA and water wash. But they have gotten better. The type of No-Clean flux and paste to use really depends on each individual assembly, the machines used, settings, and the environme
