PCB, known as printed circuit board in Chinese, is known as the mother of electronic products. It is the key interconnect for assembling electronic parts, and plays a vital role in most electronic equipment and products. At present, China's 5G base station laying process, the three major operators have given a timetable. Insiders said [...]
There are four main electroplating methods in the circuit board: finger-row electroplating, through-hole electroplating, rolling wheel selective electroplating and brush electroplating. Here is a brief introduction: Finger row plating Rare metals need to be plated on plate edge connectors, plate edge protruding contacts, or gold fingers to provide lower contact resistance and higher wear resistance. [...]
Important influence of printed circuit board PCB layout, to a certain extent determines the PCB manufacture, installation and maintenance cost, in the electronic design tends to high density, each electronics PCB layout is particularly important, good PCB layout design, often can achieve higher completion rate, reduce the jump line distribution, the attachment between the electromagnetic [...]
First, the importance of thermal design Power supply products most of the electrical energy consumed by electronic devices during the working life is converted into heat emission, except for useful work. The heat generated by electronic equipment makes the internal temperature rise rapidly. If the heat is not released in time, the equipment will continue [...]
For a new design of the circuit board, debugging will often encounter some difficulties, especially when the board is larger, more components, often do not start. But if you master a reasonable debugging method, debugging will be twice the result with half the effort. For the new PCB board we just got back, we should [...]
This article discusses seven basic (and important) techniques and strategies that can be used by both novice and veteran alike. By paying more attention to these techniques during the design process, the number of design returns, design time and overall diagnostic difficulties can be reduced. Tip 1: focus on manufacturing methods and OEM chemical processes [...]
Laser marking machine mainly USES laser to mark, in fact, mainly through the beam of words printed on the product, but we can not see the trace. Laser marking machine is mainly used in fine, high precision products, through the beam can be very complete mark. But the laser marking machine will not hurt the [...]
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 [...]
