Poor hole weldability of circuit board will lead to virtual welding defects, which will affect the parameters of components in the circuit, lead to instability of multi-layer board components and inner layer wire conduction, and cause the whole circuit function failure. The so-called weldability is the metal surface by molten solder wet property, that is, [...]
As is known to all, PCB industry is directly related to plastics and chemical industry. A little carelessness will cause fire pollution and other disasters, threatening public safety. Faced with the promotion of environmental protection and safety awareness in the global electronic industry chain, the domestic PCB industry should be more vigilant. BBS on August [...]

With the rapid update of electronic products, the waste of printed circuit boards (PCB), the main component of electronic waste, is also increasing. The pollution caused by PCB waste to the environment has attracted the attention of many countries. In the waste PCB, it contains lead, mercury, hexavalent chromium and other heavy metals. In the [...]
With the scrapping of a large number of household appliances, the amount of waste circuit boards is increasing, and its recycling value has attracted the attention of many investors, becoming a promising industry. The composition of the waste circuit board is complex, difficult to recover and treat, and the circuit board in the production process [...]
In order to solve the problem of time-consuming calibration, measurement equipment manufacturers have introduced Ecal electronic calibration method [7], which is a transmission standard. The calibration accuracy is mainly determined by the original calibration parts. Meanwhile, the stability of the test cable, the repeatability of the test fixture device and the interpolation algorithm of test [...]
