Whether you are a large industrial original equipment manufacturer making military supplies or a small electronics company designing home electronics, you are going to need printed circuit boards that will function properly. If you are purchasing your circuit boards from a third party, have a checklist in place of everything you will need from the PCB. Knowing what you are looking for allows you to ask the appropriate questions of the supplier.
Given that many electronic appliances factory customers ignore the importance of quality, the blind pursuit of the price situation. To make each customer can be assured to enjoy high-quality products, we are particularly demystify new and old customers that some risks of the circuit boards used in the process. In here disclosure excellent PCB circuit board manufacturing some of the little-known details in order to allow each user to fully understand the PCB circuit board products, more rational choice of suppliers.
Short circuit, open resistance, Resistance welding bubbly, yellow color, Off the oil, unstable, these are the most common problems for the circuit board.
Above problems appeared in the market are the most common problems of the circuit boards, according to statistics, more than 60% of users on the market in use process has the appearance of different level. The most fundamental reason is that the circuit board manufacturers unscientific, irrational mix, production technology, however, and the use of cheap inferior material selection, etc., after the tin stove thermal expansion and contraction reactions: the light from a small fraction of the solder bubble, large area will cause severe ups and downs from the base line, delamination, rocker, badly discolored oil off the deadly serious problem, a huge loss to the customer.
First of the fundamental reason:
The manufacturers are unscientific. At present, the circuit board production system, most manufacturers use the past tense feeling of traditional production and quality by inertia, using old-fashioned antique methods to fight cheap grab one and they do, to achieve low-input high-profit purposes, the application of this method has been very general, technology is relatively common. However, it 's inefficient, inconsistent quality, so most problems arise, to post- sales service increased workload, especially fatal problem more time to the customer, resulting in serious consequences unpredictable economy, their self-improvement and does not accept advanced machine control quality does not recognize, and believe that had previously been doing it, why high into the machine, after all, many bosses are circuit board background, high into the machine proved to work under limited capacity, but also the achievements of the 'take a passive attitude towards one's work', Zhongshan Wanglong electronic circuit board is currently used in digital control production, improve product quality and efficiency for the production of the first self-test, QC, QA recheck etc., interlocking, accountability, promote products, short open reduced to a minimum or even zero; passing rate is very high.
Second of the fundamental reason:
Collocation is not reasonable. Part of the manufacturers hold a post without qualifications, grade A material production planning process replace with grade B or C grade material production to the customer. Although the appearance is indistinguishable, respectively, do not think there is a problem, but sooner or later, pass the test of time, problems are exposed.
Third of the fundamental reason:
Production processes and raw materials, but off select cheaper inferior. Currently, the Internet can find many appliances circuit board manufacturer, and varied. However, independent research and development, and has the core technology and has a certain production scale of the manufacturers are small. Most manufacturers to reduce production costs, outsourced foundry , processing plant employees do not understand our industrial products, will be in accordance with the general requirements to the production of civilian products. Even semi-finished circuit board into the machine faster processing time is adjusted to conserve electricity. A large area of treatment is not often appear out of oil in place, location not corrected, in order to catch the piece pursue personal interests of efficiency , resulting in exposed copper character deviation and so on. Cheap grab customer orders, for example: A factory quotes 100, B factory will tell you 80 quickly, as a customer you heard cheaper, in order to get more benefits, will choose B factory. To further reduce cost, we understand very much counterfeit manufacturers even purchase raw materials, scrap uneven, the overall thickness of the copper foil thickness is not uniform. Reported low in front of customers, do not take "measures" how do draw products? Some customers receive a product that is less than three months on the problem. Thus finally Electronics Factory customers suffer!
