Steve: I thought Kyzen products were "additives" to either aqueous or semiaqueous inline or batch machine cleaning processes. I'm trying to clean the no-clean residue from a few components that can not bear to see water. Can you use Kyzen products

Reaching out to all conformal coating experts, please help! While setting up conformal coating using the automated atomized spray, we observing issues associated with conformal coating wetting on the following regions: 1) Component edges 2) Metalli

Hi Chrys, Hate to bring you down, but, wave solder pallets exposed to any kind of flux is subject to "Build up" on the carrier. You still have to clean them, hopefully on a regular basis.If the pallet is being run in a high production envirnment, I w

We successfully clean WS flux on 1mm and 1.25mm pitch BGA. For 0.8mm pitch BGA, we use no clean, because we cannot remove the flux residue from under them efficiently. Use ion chromatography testing to be sure it is clean under the BGA. IC is the on

We received about 5K assembly boards from china. They left flux residu on top of the board and the flux they use was different than us. RESULT ... we use a translucent cylicon to cover the board and it was not possible to dry the cylicon because of

Assemblers often assume that the board and component suppliers provide them with clean product. This was not a problem when everyone used water washable fluxes, because the water washing used to clean the flux residues also cleaned the board and com

Dave, A low residue/No residue flux does exist that when an excessive amount of flux is applied it would only create a cosmetic problem not a reliability issue. The active ingredients are neutralized by the heat applied in the soldering machine and

We recently made the switch to no-clean and the wurface mount is turning out beautifully. However, the wave solder process continues to put up a fight; we are getting a white residue on the surface of the PCB. The residue is not localized to just t

It depends on the flux and the down-stream processing ... * If there is adequate down-stream cleaning: We are ambivalent. * If the flux is low residue and there in no down-stream cleaning: We don't like using a syringe because it squirts liquid flux

Well... Some are worse than others... How can you identify that it is caused by uncured mask and not flux residues? The flux is from indium, 3592. Some research in their tech library revealed that either Kyzen or Zestron would work, which is the re
