Using a flux pen sounds like a good idea. Comments are: * I assume you�re talking aqueous flux. If not, some NC flux pens leave white residues. Nearly all of 15 samples suffered to varying degrees with white residues. * Use the same flux that you

We use NC flux exclusively for SMT and wave soldering. And it is a fairly old formula from Multicore, though we are currently qualifying a new formula. The automated soldering does not appear to be a problem. It is only the hand soldering that causes

Excellent question. Alloy development is relatively easy compared to flux formulation. New fluxes for Pb-Free alloys need upgrades in 2 critical areas: 1) thermal stability 2) oxygen barrier efficiency Since the Pb-Free alloys require reflow proce

Hello Dr. Lee, Will no-clean fluxes be more of a challenge to develop?

Sorry, the layer is made of flux.

I don't know the name of the flux. but is a no-clean solder paste.

Anyone have a flux that is good at preventing bridges for this application?

esoderberg: So, why do you want to clean your no-clean flux residues?

Hi, Yes, I would hate to resort to cleaning, but the product must be clean. We have been using palettes to keep most of the flux off the PCB, but there is still residue around the connectors. Does anyone suggest a good no clean flux to use with le
