Electrical component having presoldered surface with flux reservoirs

A presoldered prefluxed electrical component or connector (30), which can protect the flux from wearing off the surface of solder during shipping and handling. The electrical component can include a terminal pad (10). A layer of solder (12) can be on the terminal pad. The layer of solder can have a...

More Information
Summary:A presoldered prefluxed electrical component or connector (30), which can protect the flux from wearing off the surface of solder during shipping and handling. The electrical component can include a terminal pad (10). A layer of solder (12) can be on the terminal pad. The layer of solder can have a surface with a series of generally equally spaced apart flux wells (16) formed in the surface of the solder for protectively storing and retaining flux therein. The flux wells can have a lateral dimension of at least 0.05 mm and a depth of at least 0.023 mm that is deep enough for retaining a quantity of flux therein when flux on the surface of the layer of solder wears off during shipping and/or handling.
