ChemBrite is a powerful organic solder and tin deoxidizer and brightener. The organic acids in ChemBrite, combined with other coordinating compounds, give optimum deoxidizing. They are especially important in conditioning printed circuit boards (PCB’s) where the copper etch used is unusually aggressive (which results in a tough oxide film on the solder), or when the solder conditioning time is quite short. Oxides remaining on circuit boards result in a white haze after the board is fused.
ChemBrite is not as corrosive as solder conditioners based on mineral acids, like HCl or HF; this allows a longer lag time between etching and fusing with minimal white haze buildup.
ChemBrite has also been used to clean up tin plating in the lead frame industry, prior to gold plating.
