n the process of PCB design, wiring generally has three levels: the first is the cloth, which is the most basic entry requirements of PCB design; The second is to meet the electrical performance, which is to measure whether a PCB board qualified standard,
Check the network DRC and structureQuality control is an important part of PCB design process. General quality control means include: design self-inspection, design mutual inspection, expert review meeting, special inspection, etc.

Before the PCB is formally processed into the board, the circuit board designer needs to communicate with the PE of the PCB plate supplier factory to reply the manufacturer's confirmation questions about PCB board processing.This includes but is not limit
Impedance Controlled PCB Design1 IntroductionWith the development of science and technology, especially in the progress of integrated circuit materials, the calculation speed has been significantly improved, and the integrated circuit has been promoted to
At this time, even if only a small high frequency current flows through the wire, there will be a certain high frequency voltage drop. Therefore, for high frequency circuits, the PCB layout is as compact as possible so that the printed wires are as short
The PCB process design requirements are introduced in detail: 1, test point addition, 2, optical location point, 3, add working edge, 4, film file output, 5, plate rules, 6, board information annotation
the general double panel copying board is much simpler than the multi-layer copying board, multi-layer copying board is prone to inaccurate situation, So the multilayer board copy board to be particularly careful and careful (which internal through holes
PCB copying board is to scan the circuit board, record the location of the components in detail, and then remove the components to arrange the material purchase, and scan the empty board into pictures, processing and restoring to the drawing file.
Kingford is a PCB company engaged in the production and assembly of circuit boards. We not only sell PCBA, but also have many strategies related to PCB design and PCB proofing. Next, let me introduce you to some matters related to PCB.
The assembly of both cartridge components and surface assembly components is called hybrid assembly, referred to as mixed assembly, and the assembly using all surface assembly components is called full surface mount. PCBA assembly method and process flow
Manufacturing of the basic material is the substrate, we generally say what is the substrate, refers to the substrate is copper plate. Today, it is an integral part of most electronic products
