PCBsupplierChina learned speaking of the circuit board, many people should be no stranger, because we can see it everywhere in life, as small as Bluetooth headphones, electronic watches, calculators, as large as computers, communications equipment, military/aerospace systems, wherever integrated circuits are needed, PCB can not be separated from the carrying electronic devices.

​

Before the appearance of PCB, the electronic components were directly connected with wires, and the equipment with a large amount of components was often confused, and there were great security risks and easy to make mistakes.

Or use this commonly known as the hole board of the multipurpose PCB board

So how do great circuit boards get created?

Paul Eisler

This has to mention the "father of PCB" Austrian Paul Eisler (Paul Eisler), in 1936, Paul Eisler first used printed circuit boards in radio devices.

PCBmanufacturerChina talk Eisler developed the concept of using etched foils to record traces on a substrate. At first no one really paid attention to this invention, until 1943, in order to make a bomb explosion timing device, the Americans used printed circuits as proximity fuzes on the bomb, which began to be widely used. The Americans also used it in military radios.

Since then, the circuit board has become famous....

It's been developing...

In 1948, the United States officially approved the invention for commercial use.

By the early 1950s, copper foil etching became the mainstream of PCB manufacturing technology, and single panels began to be produced.

In the 1960s, the mass production of perforated metallized double-sided PCB was realized.

In the 1970s, multi-layer PCBS developed rapidly and continued to develop in the direction of high precision, high density, small wire holes, high reliability, low cost and automated continuous production.

In the 1980s, surface-mounted printed boards (SMT) gradually replaced plug-in PCBS and became the mainstream of production.

Since the 1990s, surface mounting has further developed from flat package (QFP) to spherical array package (BGA).

Since entering the 21st century, high density BGA, chip-level packaging and organic laminate material as the substrate multi-chip module packaging printed board has been rapidly developed.

The development history of circuit board in China

In 1956, China began PCB development work.

60-70 years, began mass production of single panel, but at that time was affected by various factors, printed board technology development is slow, making the entire production technology behind the advanced level of foreign countries.

By the 1980s, the advanced level of single-sided, double-sided and multi-layer printed board production lines were introduced from abroad.

In the 1990s, Hong Kong and Taiwan manufacturers have come to the mainland to set up joint ventures and wholly-owned factories, making China's printed board output and technology by leaps and bounds.

In 2002, it became the third largest PCB producer.

It was in this year that Deep Connection Circuit was established, and now it has gone through 21 years

.Established in 2002 in Shenzhen, China.
