Since the mid-1950s, printed circuit boards have been widely used.
Before the PCB appeared, the interconnection between the electronic components are based on direct connection to complete the wire. Nowadays, the wires are only used in the laboratory to do experimental applications; printed circuit boards in the electronics industry has certainly occupied the absolute control of the status.
Today, pcb has been widely used in almost all electronic products, including communications, aerospace, industrial medical, consumer electronics, automotive electronics and other industries.
