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

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

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

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

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

In the following thread, http://www.smtnet.com/electronicsforum/view_message.cfm?message=9584& John Thorup touched on some applications where no-clean fluxes could be a bad idea. I'm looking for some more detailed info. (papers, references, texts

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

Awww Stevo, just chill. I think of NC as the process engineers' full employment material. Water solubles are for wimps!!! Har har har

I am looking for IPC or other published standards that specify cleanliness levels for: 1) solder paste stencils 2) selective solder pallets When we cleaned PCB's we used a limit of 4 M-ohms. Now that we have transitioned to No-Clean, I am wonderi
