In July of this year, our NASF Report featured a major success for the surface finishing industry, the results of a 2014-2016 study of wastewater discharged to the POTWs in Milwaukee.  What follows here is the story going back 30 years, when an initial study of Milwaukee metal finishers’ discharge to the POTWs dramatically refuted the negative image portrayed by others.  It’s only gotten better since.

This NASF-AESF Foundation research project report covers the ninth quarter of project work (April June 2022) at Wayne State University in Detroit. The major activities in this report period are: (1) refinement of the sustainability assessment method for technology evaluation with case studies, (2) development of a journal paper and one conference paper, and (3) a presentation at NASF SUR/FIN 2022 in Rosemont, Illinois.

Immersion tin and lead-free hot air solder leveling (HASL) coatings based on SnCu or SnAgCu alloys are widely used as surface finish materials for printed circuit boards (PCB). These coatings prevent the underlying copper from corrosion and preserve its solderability during lead-free assembly processes and for a long storage life of PCBs.

Cites difficult business conditions in California, and the settlement of a potential lawsuit threatened by the Santa Barbara-based Environmental Defense Center.

This NASF-AESF Foundation research project report covers the twelfth quarter of project work (January-March 2023) at Wayne State University in Detroit.  In this period, our main effort concentrated on documenting technical content that was yet to be reported, including analysis of costs for specific technologies for sustainability improvement.

Phosphorus is important to platers because it is a key component of most electroless nickel deposits which contain about 5-10% (by wt) phosphorus.  As far as the human body is concerned, there is no substitute for phosphorus.

It is important to understand the various aspects of catalytic oxidation and consider options such as monitoring inlet/outlet temperatures, T across the catalyst, periodic laboratory testing of catalyst samples and preventive maintenance procedures as means of assuring continuous compliance…
