Protective coatings are used to enhance the performance and reliability of printed circuit board assemblies for use in harsh environments such as underwater, aerospace and military applications. Manufacturers of consumer electronics products are increasingly using contouring coatings as an economical way to improve the reliability of their products. When a printed circuit assembly board without [...]
1. Traditional plated through hole The most common and cheapest interlayer interconnection technology is the traditional through - hole plating technology. Figure 1 shows an example of a six - layer plated through - hole plate. In this technique, all holes are drilled through the panel, regardless of whether they are used as component holes [...]
The name of the circuit board has: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate board, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board. The circuit board makes the circuit mini and [...]
Abstract: it is an accepted principle that in all analog printed circuit boards, the signal line should be as short as possible. This is because the longer the signal line is, the more induction and capacitance will be donated in the circuit, which is undesirable. The reality is that it is impossible to make all [...]
Using the newly developed software technology, the parallel design method can accomplish the efficient parallel circuit board design. This new technology enables multiple designers, multiple processes, and different kinds of tools to work on the same design database at the same time and significantly increases design productivity. Therefore, when it comes to concurrent design method [...]
Speaking of PCB board, many friends will think that it can be seen everywhere around us, from all household appliances, all kinds of accessories in the computer, to all kinds of digital products, almost all electronic products will use PCB board, then what is PCB board A PCB board is a PrintedCircuitBlock, a printed circuit [...]

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 [...]
