The positioning of NC milling is to use the positioning pin to locate the printed board to be processed to the working table of the milling machine, so as to conveniently and accurately process the shape of the printed board.
Circuit board negative circuit or copper surface is transparent, positive circuit or copper surface is black
Signal integrity circuit board design criteria include SI problems, pre-design preparation, cascade, crosstalk and impedance control, high-speed nodes, technology selection, pre-wiring stage, post-wiring SI simulation, post-manufacturing stage, model sele
In commercial production, two laser technologies are available for PCB laser drilling. CO2 laser, UV laser. In order to meet the increasing demand for micropore productivity, many manufacturers have begun to introduce two-head laser drilling systems.
The bubbling of the circuit board is actually the problem of poor binding force of the board, that is, the surface quality of the board, which includes the cleanliness of the board and the surface microscopic roughness (or surface energy).
In this article, you will be able to learn how to design your own professional PCB board (including schematics, PCB layout, gerber generation and 3D models). We will provide you with the best tips and tricks, including free software that will help you imp
The size and type of embedded circuits vary by microprocessor, component, and operating system, but most importantly is the complexity of the software, whose code ranges from a few hundred bytes to several megabytes.
In PCB electroplating, the chemical analysis of organic compounds and metal additives is more and more complex, and the chemical reaction process is more and more accurate.
these devices must acquire higher clamp voltages and switching frequencies, with the accompanying heat dissipation capability. Here, we consider the influence of different cooling PCB pads on IGBT thermal performance under different working conditions.
PCB multilayer board covered with copper laminate material. When quality problems occur in the actual manufacturing process, PCB laminate is the test item that must be carried out to cause the problems in the production process.
We more or less will encounter difficulties, difficulties are not terrible, the way is always more than difficult
Testing PCB board should pay attention to insulation performance, working principle, test instrument internal resistance, power integrated circuit heat dissipation, welding quality, do not easily determine the damage of integrated circuit and other proble
