PCB development

development path

Printed circuit board was created by the Austrian Paul Eisler, in 1936, he first used the printed circuit board in the radio.

In 1943, the Americans mostly applied the technology to military radios. In 1948, the United States officially recognized the invention for commercial use. Since the mid-1950s, printed circuit boards began to be widely used.

Prior to the advent of PCBs, the interconnections between electronic components were done directly by wire.

Nowadays, circuit boards exist only in laboratory applications. Printed circuit boards (PCBs) have certainly assumed absolute control in the electronics industry.

Printed board development from single to double-sided, multi-layer and flexible, and still maintain their respective trends.

Due to the constant development of high-precision, high-density and high-reliability, the continuous reduction of the size, the reduction of the cost and the improvement of the performance enable the printed circuit board to maintain strong vitality in the future development of electronic equipment.

At home and abroad on the future of PCB manufacturing technology development is basically the same discussion, that is, to the high density, high precision, fine diameter, fine wire, fine pitch, high reliability, multi-layer, high speed transmission, In the direction of development, in the production at the same time to improve productivity, reduce costs, reduce pollution, adapt to multi-species, small batch production direction. Printed circuit technology development level, generally printed on the line width, aperture, thickness / aperture ratio as the representative.
