Printed circuit boards, also known as printed circuit boards, printed circuit boards, multilayer pcb advantages,electronic components procurement,smt pcb assembly process,OEM service,pcb design price,manufacturer,supplier,Design,solution,price,often use the English abbreviation PCB (Printed circuit board), is an important electronic component, is the support of electronic components, is the provider of electronic components line connection. Because it is made using electronic printing technology, it is called a "printing" circuit board. Prior to the advent of printed circuit boards, the interconnection between electronic components relied on wires to form a complete line. Today, circuit breadboards exist only as an effective experimental tool, and printed circuit boards have become the dominant position in the electronics industry. At the beginning of the 20th century, in order to simplify the production of electronic devices, reduce the wiring between electronic components, and reduce the manufacturing cost, the method of replacing wiring by printing was started. For thirty years, engineers have been proposing to wire metal conductors on insulated substrates. The most successful is that in 1925, Charles Ducas of the United States printed the circuit pattern on the insulated substrate, and then successfully established the conductor for wiring by electroplating.
