Circuit board proofing manufacturer production process 1. Contact the manufacturer Need to tell manufacturer of document, technological requirement, quantity above all. Second, cutting Objective: according to the requirements of engineering data MI, cut into small pieces on the large sheets meeting the requirements. Small pieces of sheet material that meet customer requirements. Process: plate material [...]
Gold and oxygen halftime transistor is not always the first choice of analog circuit board fast proofing circuit design engineers, because analog circuit design focuses on performance parameters. Such as transistor transconductance or current drive, BJT can better meet the needs of analog circuits. However, with the continuous improvement of gold-oxygen half-effect transistor technology, CMOS [...]
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 [...]
