PCB knowledge: Printed circuit boards
Printed circuit board (short for PCB) is an important electronic part. It is the supporting body of electronic component and the electrical connection supporter of electronic component. Since it’s made by electronic printing, it’s called printed circuit board.
?
Role
After PCBs are applied in electronic equipment, since it’s consistency of the same board, it confidently avoids the error of manual wiring. PCB can achieve the automatic pick and place or surface mounting, automatic soldering, automatic inspection. It guarantees the quality of electronic equipment. The labor productivity is improved, the cost is reduced and the maintenance is convenient.
?
Development
Printed circuit board develops from single sided to double sided, multilayer and flexible, and still maintain their own development trends. Due to the continuous development of high precision, high density and high reliability, and constantly reduce the volume, reduce costs, improve performance, making the printed circuit board in the future development of electronic equipment, still maintained a strong vitality.
Review on the future development trend, the manufacturing technology of PCB mainly is consistent, namely high density, high precision, small diameter, thin track, fine pitch, high reliable, multilayer, high-speed transmission, light weight, thin direction. To improve productivity, reduce costs, reduce pollution, adapt to many varieties and small batch production are the production direction at the same time. The technology development level of printed circuit boards, it is regarded with line width, PCB drill, aspect ratio as a representative.
?
History
The creator of printed circuit board is Austrian engineer Paul Eisler. He invented the printed circuit as part of a radio set while working in England around 1936. In 1943, The USA began to use the technology on military radio. In 1948, the USA released the invention for commercial use. Since the mid-1950s, printed circuits became commonplace in consumer electronics and began to be widely used.
?
Before PCB, the interconnection between the electronic components is relying on the wires directly connected to complete. Nowadays, only in the laboratory test wire exists. Printed circuit board in the electronics industry has occupied the absolute control status.

FAQ
How do you pack the PCBs?
PCBs are packed with Polyethylene air cushion film(vacuum plastic bags) per 20-25 pieces. Pearl cotton (Polyethylene foamed sheet) are put inside carton box.
The hardness of carton box is KK grade(the highest hardness). Maximum gross weight for one carton is less than 12 kgs.
