Dip soldering a small tank containing molten solder. PCB with mounted components is dipped manually into the tank when the molten solder sticks to the exposed metallic areas of the board. Dip soldering is accomplished by submerging parts to be joined into a molten solder bath. Thus, all components surfaces are coated with filler metal. Solders have low surface tension and high wetting capability. There are many types of solders, each used for different applications. Such as Lead-Silver for strength at higher than room temperature. Tin-Lead is used for General Purpose; Tin-Zinc is used for Aluminum; Cadmium-Silver is used for strength at
Sopormetal Sopormetal Sopormetal International Group was founded on February 2, 1985. It began as a Portuguese company supplying brazing materials, silver and copper brazing solders. SOPORMETAL is a producer of brazing materials such as silver solders, copper/phosphorus, soft solders and fluxes. Cadmium-free silver solder, special alloys and tri-metal alloys for the entire industry, as well as several special alloys in the form of rod, strips, rings and various preforms. Coated silver solders with different ratios having regard the technology used for brazing and fusion technical parameters. Copper phosphorus alloys with and without silver for all sectors, as well with different types
