The major considerations when selecting a flux should be the performance requirements of the end product, relative complexity of the assembly, and acceptability of residues or other cosmetic concerns.
This paper reviews the J-STD-004 and how it is used in flux categorization and selection. It also discusses the major types of flux formulations available, and the design, process and reliability implications of using each type. The purpose of the paper is to help the reader make an informed choice when selecting wave solder fluxes for lead-free processing.
