PCB (printed circuit board) is a printed circuit board, which is one of the important components of the electronics industry. Almost every kind of electronic equipment, from electronic watches, calculators, to computers, communication electronic equi
Classification according to the number of circuit layers: Divided into single panel, double panel and multilayer board. Common multi-layer boards are generally 4-layer boards or 6-layer boards, and complex multi-layer boards can reach dozens of layer
To get the best performance from electronic circuits, the layout of components and the layout of wires are important. In order to design good quality, low cost PCB. The following general principles should be followed:
layout
Back drilling is actually a special kind of deep-drilling control. In the production of multi-layer boards, such as the production of 12-layer boards, we need to connect the first layer to the ninth layer. Usually we drill through holes (one-time dri
Polar Instruments, the leading manufacturer of high-speed PCB design tools for manufacturers and OEMs, announced the expansion of the productivity of Si8000m and Si9000e PCB transmission line field solution tools; XFE "Xhatch Flex Enhancement" is the
After the board surface is oxidized, a fluff layer (copper oxide and cuprous oxide) is formed.In essence, the villi will be eroded by acid or reducing solution, making the originally black or red-brown villi appear red copper.
Via hole is also called via hole. In order to meet customer requirements, the via holes must be plugged in the PCB process. Through practice, it has been found that in the process of plugging, if the traditional aluminum sheet plugging process is cha
