Our PCBs manufactured with no clean flux have a waxy film on the board...is this normal? Our contract manufacturer recently switched to no clean from water wash. Thanks Carl

I need an evaluation process to prove to a customer that our no-clean process does not leave excessive residue? Any ideas?

Many times after initially cleaning in the solvents recommended by the paste/material manufacturer, a light white haze may still be visable...try using a soft bristle brush to remove the remaining residues. By this time the residues that remain will

KS: You're correct. The standoff on a 1.00mm and 1.25mm BGA is high enough to allow cleaning. The standoff on 0.8mm BGA does not allow proper cleaning, even with saponifiers.

Hi Scott - No clean assemblies have a very low tolerance for processing residues, and long term reliability is compromised if residues from incoming bare boards, components, or un-solublized flux residues are not dealt with. It is critical to contro

| hello to everybody, | we have a really satisfactory no clean process, both smt/reflow and wave soldering, but we get troubles with defects rework; | does anybody know how to eliminate flux residues or how not to produce them during rework operatio

Thank you guys for your help, I do not clean any on my assemblies who are build by the SMT an wave soldering department, we do used liquid fluxes Kester 951 and cored wire keester 245, usually it�s for batteries connector, led, terminal and wire rap

I have few problems below, 1.I had problem with clean glue stencil at the midle of the process and after the process. 2.Very hard to Fix the bridging on the (close pin) connectors through the wave. Anyone can help on this. Thanks Van
