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?

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

Armando: We're guessing that the white residue is on the laminate also. We believe that the residue has something to do with your low residue flux and water. It could be: * Water contamination in the flux. * Poor selection of preheat temperature that

As a minimum, you should observe the recommendations for disposal in your flux supplier's MSDS. For one VOC-Free Flux, the MSDS says something like: Waste Disposal Methods: Scrap material may be disposed of, by a licensed waste disposal company or
