Is the no clean solder paste as good? We are wondering if we can elliminate the wash when we change from through hole to surface mount.

There is also a new cleanliness tester that looks at localized areas to provide a cleanliness reading and can extract a sample to use in ion chromatography testing. You can find out about it here: http://www.residues.com/C3.html

The Jury is still out on no-clean reliability in the long term as no-clean didn't gain wide spread acceptance until the early 1990's. Also, in today's disposable society, few products are expected to last 15-20 years. Experience has shown that if y

No clean residues can range in appearance from brownish gunk that looks like tree sap (because it is in some instances) to almost no residue at all. Is this product exposed to a wave soldering process or SMT? I would guess it's a wave process if th

There are chemistries out there that will solublize some post-solder NC flux residues. I have had success with Zestron material Vigon A200 and Petroferm material Hydrex DX. Go to http://www.zestron.com and http://www.petroferm.com These are chemical

I've a query. I have one new Customer whom insisted us to use RMA paste on their product. The problem is, on some of their products they use via hole as the test point in where all the PCB finished are ENTEK and as usual I have to print solder paste
