In board shops from Suzhou to Guadalajara, one oxidizer keeps popping up in process audits: potassium monopersulfate compound. It’s the triple-salt workhorse that quietly drives micro-etch uniformity before copper plating and ENIG, without the drama you get from permanganate residue. To be honest, the conversation has shifted from “does it work?” to “who can supply it consistently and help dial in the bath?” Three drivers I keep hearing: tighter line widths, greener chem profiles, and fewer surprises on AOI. potassium monopersulfate compound (often called PMPS/“triple salt”) offers controlled copper removal, low odor, and quick start-up. Many customers say it’s forgiving on mixed-material panels and behaves predictably across a wide temperature window. Use it in fine-line rigid boards, HDI before activation, and ENIG prep where uniform micro-roughness matters. Surprisingly, several shops reported fewer pinholes after switching to potassium monopersulfate compound, likely due to cleaner surface energy and less residue carryover. A mid-size rigid board plant replaced a permanganate pre-plate with potassium monopersulfate compound at 20 g/L, 28°C, 60 s dwell. Internal QC showed micro-etch depth 1.1–1.3 μm (Rz improved by ≈12%), scrap down ~30% on ENIG due to fewer adhesion defects, and bath life extended to ~8 turnovers with replenishment. Operators—always the real judges—liked the cleaner rinses and steadier ORP. Final note: spec sheets are great, but pilot a few panels. Tune pH and dwell for your laminate stack; you’ll see why potassium monopersulfate compound keeps showing up in best-practice lines.A Field Note on potassium monopersulfate compound for PCB Metal Surface Treatment
