Preliminary preparation—PCB structure design—PCB layout—wiring—wiring optimization and silk screen printing—network and DRC inspection and structural inspection—plate making. 1. Preliminary preparations include the preparation of component

How to solve EMI problems in multilayer PCB designThere are many ways to solve EMI problems. Modern EMI suppression methods include: using EMI suppression coatings, selecting

1. Abrasives abrasives, brush materialsVarious materials used to clean and pre-treat the PCB surface and brush the copper surface, such as polymer non-woven fabrics, or non-woven fabrics

In the production of single-sided or double-sided PCBs, the non-conducting holes or conducting holes are directly drilled after blanking; the multi-layer boards are drilled after

Online Test (ICT)ICT, that is, automatic online test, is a must-have test equipment for modern PCB manufacturers, and it is very powerful. It mainly detects

Open the PCB design drawing on the computer, light up the short-circuited network, and see which is the closest and easiest to connect to. Pay special attention

1. For the lines drawn by Protel series and AD series software, no matter which layer (including wiring layer, Keepout layer, etc.) the lines are

The routing direction of adjacent planes is orthogonal to the structureAvoid running different signal lines in the same direction on adjacent layers to reduce unnecessary

HDI is smaller and lighterThe HDI board is made of the traditional double-sided board as the core board through continuous lamination. This kind of circuit

Electrical safety distance1. Spacing between wiresAs far as the processing capabilities of mainstream PCB manufacturers are concerned, the minimum distance between wires should not be

1. Market sizeAs an important source of information interaction and perception in the era of the Internet of Things, smart sensors are an important pole
