Scope

Scope: This standard specifies the raw material requirements, production processes and control requirements, product quality indicators, sampling, inspection methods, inspection rules and marking, packaging, transportation, and storage requirements for desoldering solutions produced by reprocessing printed circuit boards (PCBs) etching waste solutions. This standard applies to desoldering solutions products produced by reprocessing printed circuit boards etching waste solutions. Main technical content: The etching desoldering waste solution is subjected to negative pressure concentration, and the distillate is recovered after three-stage absorption. The dilute nitric acid is mixed with a suitable amount of purchased 65% nitric acid to form a certain concentration of nitric acid solution, and a small amount of ferric nitrate or ferric nitrate solution and additives are added. The mixture is stirred and mixed to form a regenerated desoldering solution.
