IPC J-STD-006C prescribes the nomenclature, requirements and test methods for electronic grade solder alloys; for fluxed and non-fluxed bar, ribbon and powder solders for electronic soldering applications; and for "special" electronic grade solders. This is a quality control standard and is not intended to relate directly to the material's performance in the manufacturing process. Solders for applications other than electronics should be procured using ASTM B-32. This standard is one of a set of three joint industry standards that prescribe the requirements and test methods for soldering materials to be used in the electronics industry. The other two standards in this set are IPC/EIA J-STD-004, Requirements for Soldering Fluxes, and IPC/EIA J-STD-005, Requirements for Soldering Pastes

This "C" revision has been updated to address intentional additions to a solder alloy and impurities in the alloy. In addition, the tables and appendices have been updated with the latest alloy information.
