Printed circuit innovations, the first is the PCB product and market innovation. Printed circuit innovation, is based on technological innovation. Noise printed electronic circuit (PEC) to the PCB

April 16, the flexible PCB and assembled the world's number two industry in China, the United States MFLEX Group, wholly owned investment in Chengdu, the third dimension along flexible pcb.

In China thousands of PCB enterprises, private enterprises accounted for the majority. However, lack of funds and management experience, has constrained the domestic private enterprises to further the development of PCB. China's Printed Circuit Industry Association called on the experts, the State should formulate policies on private enterprise to give certain concessions in PCB at the same time, private PCB enterprises should try to innovate further to close to the market.

According to market research organization Frost & Sullivan forecasts the Chinese market for printed circuit board (PCB) products, the scale of demand in 2009 will reach 97.2 billion yuan, representing 18.2 percent decline the previous year; But the market will gradually recover in 2010 .

The common flexible PCB packing is to stack the flexible PCB of 10 ~ 20pcs together, and fix in a cardboard with paper rolls to avoid using tapes, because tape adhesives which contain chemical substances, if be exudative it will easily lead to discolor the terminal oxidation. When the basement membrane is a polyimide film as it can easily absorb moisture, flexible printed circuit boards should be loaded together with silica gel and desiccant into the polyethylene bags and pressurize the bags. And then cased into corrugated boxes with cushioning materials. Due to the unique shape of the flexible PCB, different form should be used different packings.
