The de facto industry standard in high speed plate design. It's awesome in every way. PCB Layout tool is absolutely first-class, a little familiar with no longer want to use other tools, wiring super cool. Simulation is also very cattle, have their own si
PCB circuit board needs reasonable design and layout of components, in order to better play out the functional advantages of the circuit board.
in multilayer PCB design, components should be placed in groups to prevent inter-group interference; The location of high-speed circuits should be arranged properly so as not to interfere with other circuits through electric or magnetic coupling; The grou
PCB welding resistance blistering is a problem that many PCB factories inevitably appear in the processing of PCB, so what causes the welding resistance blistering? The following is for you to sort out the introduction.
PCBS with multiple layers are often used in high-speed, high-performance systems, where the multiple layers are used for direct current (DC) power supplies or ground reference planes.
Shenzhen Hongyunlai Electronics is a professional pcb circuit board factory, with advanced production equipment and perfect after-sales service system. Provides more information on pcb pcb design, pcb PCB proofing, single side/multilayer PCB PCB fabricati
Before understanding the PCB design copper platinum thickness, line width and current relationship, let's understand the conversion between the PCB copper thickness in ounces, inches and millimeters: "In many data tables, PCB copper thickness is ofte...
The improvement of etching quality is closely related to the acceleration of etching rate. The faster the etching speed, the shorter the time the board stays in the etching solution, the smaller the amount of side erosion, and the etched pattern is clear
Therefore, on SMT printed boards, through holes are used only to connect the wires on both sides of the board, the number of holes is much smaller, and the diameter of the holes is much smaller. In this way, the assembly density of the circuit board can b
PCB board appearance should be smooth and flat, not warped or uneven. The appearance of PCB circuit board is usually rectangular, and the right-angle PCB board is easy to produce cards when transferring, so in the design of PCB board, to do arc Angle proc
With the growth of screen printing skills, screen printing skills occupy more and more important positions in the printed circuit manufacturing industry, its application, not only improved the production of printed circuit obedience, low production cost o
Reducing electromagnetic interference is an important part of PCB board design, as long as the design to think more about this side, naturally in the product test such as EMC test will be easier to pass.
