China PCB Assembly SMT Assembly

a thru-hole component is described as a component leaded with a wire or a metallic lead that is mounted to the board by placing the lead though plated holes in the board and then soldered. The quality of the solder joint is important for several reasons. The solder joint is the actual connection between [...]

Global PCB industry growing faster

Prior to the advent of PCBs, the interconnections between electronic components were made by directly connecting electrical wires. To simplify wiring, people printed circuit patterns on the substrates and formed pathways through copper plating. As a result, printed circuit boards came into being. Has now developed into a cornerstone of the electronic information industry. [...]
