Aim offers excellent soldering fluxes. That said your probably dealing with the local representative. The FIRST question to ask when evaluating any chemistry is "What is the Availability of the flux". Distributors don't necessarily stock all of a man

Tested recently on ENIG finish. profile as follows 100-150, 57 sec. 150 210, 46 sec. 210 + , 63 sec. Peak 231. This profile was developed for this paste as per Asahi literature. Operator said it "looked wet and smelled good"! Print quality was excel

I am running composite fixtures on my wave solder machine and after about 500 passes each (1 month)they are showing serious signs of wear in that the composite surface is bubbling up and glass fibers are also starting to show. The problem here is t

Hi Thomas Ever considered that this maybe HASL flux left on PCB as this is extremely hygroscopic and has heat transfer fluids that cannot be baked out unless you go to a temperature of around 600C. One way of testing is to leave iron tip on joint an

Thats the problem residual residue from HASL fluxes Lead free especially are worse.Very hygroscopic and out gass and produce dewetting as well over wave soldered boards especially. Leave iron on blown joint and will after several seconds fizz and pop

Who says the chlorine comes from your tap water? Our PTOW dumps boat loads of chlorine into our water periodically. Sometimes it's so bad you can smell it. We doubt that it is the source of your problem. This chlorine will volitize very quickly,
