Printed Circuit Board is a type of electronic element, which is the carrier of a circuit, and important to each electronic product. The practical components get connected to each other by the copper traces, whereas get mechanical support from a printed circuit board. CEM-1, CEM-3), polymeric plastics (resembling PI, pcb assembly PTFE), ceramics, and so on. The sometimes printed circuit boards could be 1-sided, 2-sided, or multilayered. Multilayer printed circuit board is just understood as superimposing extra copper layers outwards on the basis of a 2-sided board. The everyday stackup of 2-sided PCB. Multilayer PCB are as follows. From circuit design to material selection to PCB assembly, each step of printed circuit board manufacturing is highly customizable, which is why it is broadly used in electronic merchandise. In 1936, the founding father of printed circuit boards, Austrian Paul Eisler, first used printed circuit boards in radio installations. In 1943, Americans used printed circuit board technology in military radios. In 1947, the US Aviation Administration and the US Bureau of Standards launched the first technical seminar on PCBs. In 1948, the United States formally acknowledged the invention and used it for commercial functions. Within the early 1950s, on account of the problem of the bond strength and solder resistance of CCL’s copper foil and laminate, the performance was stable and dependable, and industrialized production was realized. Copper foil etching grew to become the mainstream of printed circuit board manufacturing technology, and manufacturing orders started. In the 1960s, the realization of large-scale manufacturing of hole metalized double-sided circuit boards. Within the 1970s, multilayer boards developed quickly and continued to develop in the path of excessive precision, excessive density, nice line small holes, high reliability, low value, and automated steady manufacturing. In the 1980s, surface mount (SMT) printed boards regularly replaced plug-in PCBs and turned the mainstream of production. Since the beginning of the twenty first century, excessive-density BGA, chip-scale packaging, and organic laminate materials have been quickly developed for multi-chip module package deal printed boards.

In 1956, China began PCB board improvement work. In the 1960s, mass production of single-sided printed circuit boards, small-quantity manufacturing of the double-sided boards and the start of the development of multilayer boards. In the 1970s, as a result of the constraints of historic conditions at that time, PCBA the event of printed circuit board technology was sluggish, making your complete production technology lag behind the superior level of foreign countries. In the 1980s, advanced degree single-sided, double-sided, multi-layer printed circuit board production strains have been introduced from abroad, which improved the manufacturing expertise stage in China. In the nineties, international printed board manufacturers in Hong Kong and Taiwan, as well as Japan, came to China to determine joint ventures and wholly-owned factories, which made China’s printed circuit board manufacturing and know-how advance by leaps and bounds. In 2002, it became the third-largest PCB manufacturing base. In 2003, printed circuit board output value, and import and export quantity exceeded US$6 billion, surpassing the United States for the primary time, changing into the world’s second-largest PCB manufacturing base. The proportion of output worth also elevated from 8.54% in 2000 to 15.30%, practically doubled. In 2006, China has changed Japan because the world’s largest PCB manufacturing base and essentially the most energetic know-how growth country.
