The working environment of the multilayer pcb will be subject to different external interferences. These interferences may be interference from the power supply, interference from the space electromagnetic field, and interference from the ground wire. So, what are the measures to suppress interference on the electronic board? 1. Filtering: A filter is a network composed…
PCB multi-layer boards are more complicated than single- and double-layer boards both in terms of design and manufacturing. Then, what difficulties should be paid attention to in the proofing of led circuit board? 1. Difficulties in alignment between soldering circuit boards layers Due to the large number of layers in multi-layer circuit boards, users have…
For general electronic products, FR4 epoxy glass fiber substrate is used, for use in higher ambient temperatures or for flexible circuit boards, polyimide fiberglass substrates are used, and for high-frequency circuits, PTFE fiberglass substrates are required; Electronic products with high heat dissipation requirements should use metal substrates. (1) A substrate with a higher glass transition…
The production process of PCB board is relatively complex, and it involves a wide range of processes, from simple mechanical processing to complex mechanical processing, common chemical reactions, photochemical, electrochemical, thermochemical and other processes, computer-aided design CAM, and many other aspects of knowledge. Because the production process is a non-continuous assembly line form, any problem…
One can’t overstate the importance of picking the right materials for making a pcb assembly. Each piece’s benefits can change greatly depending on the material you choose. Your PCB can range from a standard board to complex, bendable PCBs; in short, you’ll find a wide range of options. *Substrate When considering materials, start by looking…
