Tin Lead Plating Specifications Hi-Tech Plating produces Tin/Lead electro deposits per MIL-P … Lead-based Tin-lead (Sn-Pb) solders, also called soft solders, are commercially available with tin concentrations between 5% and 70% by weight. The greater the tin concentration, the greater the solder’s tensile and shear strengths. Lead mitigates the formation of tin whiskers, though the precise mechanism for this … See more Solder is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling. Metals or alloys … See more Flux is a reducing agent designed to help reduce (return oxidized metals to their metallic state) metal oxides at the points of contact to improve the electrical connection and mechanical strength. The two principal types of flux are acid flux (sometimes called … See more A preform is a pre-made shape of solder specially designed for the application where it is to be used.
