Problems using NC in RF circuits are peculiar. Depending on the situation [ie, circuit layout, frequency of use, processes used, materials, and what not], a particular NC flux may not work with a RF circuit. Various NC fluxes leave different levels

We are having metal migration issues with SOT 223 and TO 220 parts runing at 500V DC. We are using no clean flux and suspect that is causing the problem. Does anyone have any experience with these levels of DC voltages or know of any consulting firm

I am trying to decide what type of no clean flux I should use in our selective solder machine. We run both leaded and lead free and would like to use the same flux for both. What is everyone else using? Or do you have any recommendations?

Does this PBGA have eutectic balls? If so and the PCB is HASL finish, or has solder on the lands from BGA removal, you may not have to apply solderpaste. Check with you flux supplier to see if they offer a NC "flux paste" product, otherwise I know Mu

We are using Kester 985M in our Pillarhouse Jade. We only run SnPb, but this is a newer formulation of flux that is suitable for both lead and lead free alloys. Call the manufacturer of your selective soldering machine and get their advice. They ty

Hi, we have ERSA flow selective machine. We are using 420s-lf No-Clean flux (lead free process). It is water based. Before that we used for about 2 years in JS-EU-31 (KOKI) (alcohol based). It did excellent job (we moved to water based flux just bec

We also have a pillarhouse jade but opted for Kester 959T. The low solids content allows us to use a very small shot of flux thus resulting in low residue on the boards with great solder joints. Solderability is still good but had better results with

Por, Why do you clean no-clean flux residue?I didn't use the product you mentioned but I got some help from the folks at Cookson group last year when I did wirebonding after no-clean smt processing.check their website.Check your profile as well.unles

okay, add more flux first and try, pcb surface is not copper already, if more flux helps, than your pcb surface should be ok if not than mehanically cleaning the surface please, (like your car at home 'pol�roz�s-hungaian' I do not know the engli
