Circuit Board Components OSP PCB Oxygen Scavenger Powder Water Treatment Chemical OSP Finish
Specifications:
Product name: PCB OSP Chemical
Appearance: light blue clear water liquid
Purity: 99%
Packing: 20KG/Bucket
Temperature: 39±3degree
Time: 30-90seconds
PH: 2.7±0.2,max PH3.0
Thickness: 0.2-0.6µm
Features:
It is satisfactory for the welding performance and the performance of solder on SMT welding.
With good moisture resistance, copper surface oxidation can be prevented for about a year after treatment.
It has good heat resistance and can undergo many hot cycles.
Good adaptability to impurity flux and solder paste. Even after multiple heat cycles, the coating can still be coated with non-viscous, extremely thin and homogeneous characteristics.
5, because is a chemical reaction process, the solder resist oil, carbon paste, and most of the metal material in addition to gold there won't be coated on the surface layer and the residue rarely) (that is, the ionic contamination, so it can be used to wash process.
Because it is a water-soluble weak acetic acid solution, it contains no other solvents, so it is not only environmentally friendly, but also corrosive than the acid base solution.
7, this process in the chemical reactivity and heat are very mild, there won't be like hot the whole peaceful nickel plated gold of solder resist ink to jilt oil such as damage.
Compared with the heat wind, the problem of the soldering surface of the oil is reduced.
