Then use these technical documents and production documents to make PCB board, component welding, fly needle testing, circuit board debugging, and complete the complete copy of the original circuit board template.
It's best to take two pictures of the device's location with a digital camera. A lot of pcb circuit boards do more advanced above the diode transistor some do not pay attention to see.
The value of the matching resistance should be determined by the maximum value of the output drive current and the absorption current of the integrated circuit.
Power integrity directly affects the signal integrity of the final PCB board. Power supply integrity and signal integrity are closely related, and in many cases, the main cause of signal distortion is the power system.
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.
