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

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

No-clean is definitely a cheaper process. It will eliminte cleaning. Some issues associated with no-clean are: -- the flux stain left behind on the PCB will create a cosmetic issue. You may want to seek advice from your customers. -- next, the flux

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

Hi our company is currently using a water soluable paste. We have heard that no-clean solder paste has gotten alot better over the years and are thinking about making the switch. Our main concern is that our solder joints will not look as good as t

Good afternoon... I am pretty new to a lot of things in the electronics manufacturing realm and could use some help on some issues from the big guys... Our company is a contract manufacturer for many customers. We use multiple paste and flux types

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

I'm reworking lead free BGAs now, on a Conceptronics Freedom 3000. I use flux only (no-clean, Indium) all the time, with no issues. If you go to paste, you also understand that you still have to hit the same temperatures as with flux, as the solder i
