PCB (Printed Circuit Board), the Chinese name for the printed circuit board, also known as printed circuit boards, printed circuit boards, is an important electronic components, is the support of electronic components, electronic components is the electrical connection provider. Because it is made using electronic printing, it is called "printed" circuit board.
With the electronic products to the "light, thin, short, small" direction, PCB to high density, difficult development, so a large number of SMT, BGA PCB, PCB and customers in the placement of components required plug hole, Five roles:
(1) to prevent PCB over-wave soldering tin from the through-hole through the element surface caused by a short circuit; especially when we put the vias on the BGA pad, PCB you must first do plug hole, and then gold-plated, easy to BGA welding.
Flux remains in vias;
(C) the electronics factory surface mount and component assembly is completed after the PCB in the test machine to vacuum to form a negative pressure to complete:
(D) to prevent the surface of the solder paste into the hole caused by Weld, affecting the placement;
(E) to prevent the wave soldering when the tin beads pop, PCB resulting in short circuit.
PCB is a high pollution, high energy consumption industry, and in recent years the country more and more attention to environmental protection, PCB the requirements of enterprises will become more stringent, enterprises for environmental protection, but also to pay accordingly.
In addition, raw material prices continue to rise, the cost of labor is also rising, which led to PCB production costs continue to rise. And the appreciation of the renminbi, PCB the rise of low-cost manufacturing in Southeast Asia, making the original competition on the PCB industry has become more smoke filled.
So, how should the PCB industry respond to the new era?
Down wages Province of raw materials These savings are very limited, and the provincial raw materials, related to the quality of the PCB, as long as a quality, however, the customer will be lost, so this method is not feasible.
Some companies take into account the cost of the problem, to the central and western transfer, to reduce labor costs. But this way, but increased the other design, PCB research and development, logistics costs, long term, it is not cost-effective.
In fact, the current Internet era, there are challenges at the same time, but also to the PCB industry has brought new opportunities for development. PCB industry in the design, production, sales, logistics and other aspects, can bring new development, and these changes, perhaps better than the traditional method, more cost savings. For example, in the design, do not need to hire a professional design staff, as long as the designer can be invited on the network design, designers a lot, you can choose the right price. The cost of this design is more cost-effective than hiring full-time staff.
This shows that the Internet era to bring the PCB industry, is a new development opportunities. But after all, this is a new thing, many companies are still on the sidelines of the attitude, there are some companies have begun to test the water, and achieved good results.
