Solder and fluxes covered by this specification are intended for use in the assembly of electronic circuitry and associated electrical equipment in order to provide functionally good solder joints by means of tin-lead solders. Additional solder alloys are included for special purpose electronic assemblies. For fluxing/soldering purposes, a soldered joint is that which functions as both a mechanical and an electrical connection point. It is considered to be an electrical connection (i.e. in grounding applications) through a printed wiring board. Additional solder alloys are included for special purpose electronic assembly use. Appropriate tests and visual examination should be used to insure the post-cleaning absence of deleterious flux residues. To insure maximum reliability and service life, soldering fluxes used in the solder coating, assembly, and/or repair of electronic equipments and components should be selected and used in compliance with the requirements of the applicable soldering process specifications and standards.
