Without interfering with the chemical or physical structure, the bonding of same or different metals with each other both electrically and mechanically by using another metal or alloy as the filler or retention.
Only filler material moltens not the metals to be connected. Electronic soldering technology is used for connecting the components to each other or to the pad on the PCB both mechanically and electrically. As in all production, quality; is a chain of interconnected rings. Soldering is one of the most important ring in electronic production. No matter how well the design is, how good the components are selected, the quality of your production depends on the soldering bonding them.
