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 [...]
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 [...]
