OK...I'm hooked on this subject. Were changing from NiAu to OSP as a "savings" and not because we choose too. So far we have had great success with BGA and are working on TSOP, SOP, etc. The only thing we have come to dislike so far is the ring aroun

Hi Dave F, thanks for the reply, what I did was evaluate, the ASC International, 3D solder paste VOLUME m/c, thru a local s'pore vendor, and this sales-guy is pulling a rip-off, coz his knowledge of the m/c seems inconsistent. I had sent ASC a emai

Dear Mr. Chan, ASC International apologizes for any confusion or mis-representation you have experienced. It is unfortunate that we did not receive your email regarding local S'pore ASC distributors. If, after all this, you may still have an int

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

No-clean solder paste is definately a trend for tomorrow. However, there are several points you need to consider before you shift from WS to no-clean: 1. Component quality - No-clean solder paste generally (not essentially) get a lower avtivity than

Hi Jacob, NC vs WS, what a story! No-clean paste means no-clean for your products but what a mess it makes in your reflow systems. If you are a contract maunufacturer of high volume production, then No-Clean is they way to go. This helps keep your co

Others make good points. Consider "TP-1115 - Selection & Implementation Strategy for A Low-Residue No-Clean Process" as a starting point. Remember that in-bound components and boards can be loaded with unNC res that can turn the best implemented
