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

Glenn, There are both very good VOC-Free fluxes as well as alcohol based fluxes out there. This should be your primary focus if you are so lucky as to have to opportunity to actually select a flux! The use of nitrogen will benefit any no-clean pro

ROSA is a surface restoration technique that removes hard to reduce species like metal oxides or sulfides. At the time of its development, the focus was on solderability and compliance to environmental regulations. Industry trends and regulatory changes as a result of the Montreal Protocol were the driver for much of the concern over environmental compliance. The result was an increase in the development of no-clean and water soluble fluxes and the removal of halogenated cleaning chemistries.

Aluminum is a metal that it is hard to solder due to the high surface tension difference between it and molten solder alloy. This occurs because aluminum rapidly forms a tenacious oxide layer whenever it is exposed to oxygen in the air. The oxide layer is responsible for the high surface tension difference between the aluminum and the solder and impedes the solder from spreading evenly on an aluminum surface. There are hundreds of aluminum alloys available in the marketplace; it is important to identify the form of aluminum that is being soldered. Once this is done, an appropriate soldering technique can be chosen for soldering the specific aluminum alloy under consideration. Direct aluminum soldering eliminates using expensive plating techniques to prepare the aluminum surface for soldering.
