Scope

This standard specifies the classification, chemical composition, test methods, inspection rules, marking, packaging, transportation, and storage of phosphorus copper anodes. This standard applies to phosphorus copper anodes required for sulfuric acid electroplating copper on printed circuit boards. 1. Revise the original industry standard based on the latest technical information, production processes, and product performance characteristics of ordinary phosphorus copper anodes; 2. Supplement the content of the original industry standard with technical information, production processes, and product performance characteristics of microcrystalline phosphorus copper to meet the requirements of high-performance PCB board production. -------- This standard replaces CPCA 4305—2005 "Phosphorus Copper Anodes". Compared with CPCA 4305—2005, the main changes in the content are as follows: — The relevant values have been modified in accordance with the provisions of GB/T 8170—2008 "Rules for the Rounding of Numerical Values and the Representation and Judgment of Limit Values" (see 3.2.1); — Phosphorus copper anodes have been classified according to average grain size (see 3.1).
