China Wholesale Soldering Pcb Components Pricelist - 14 Layer Blind Buried Via PCB – Huihe
About Blind Buried Via PCB Blind vias and buried vias are two ways to establish connections between layers of printed circuit board. The blind vias of the printed circuit board are copper-plated vias that can be connected to the outer layer through most of the inner layer. The burrow connects two or more inner layers but does not penetrate the outer layer. Use microblind vias to increase line distribution density, improve radio frequency and electromagnetic interference, heat conduction,... -
China Wholesale Round Circuit Board Manufacturers - 4 Layer ENIG impedance half hole PCB 13633 – Huihe
Half hole splicing mode By using the stamp hole splicing method, the purpose is to make the connecting bar between the small plate and the small plate. In order to facilitate the cutting, some holes will be opened on the top of the bar (the diameter of the conventional hole is 0.65-0.85 MM), which is the stamp hole. Now the board has to pass the SMD machine, so when you do the PCB, you can connect the board too many PCB. at a time After the SMD, the back board should be separated, and th... -

Effect of different types of copper foil on electrical properties In the design of high-frequency PCB, designers usually pay more attention to the dielectric constant (DK) and tangent loss (DF) of PCB when selecting materials, and only pay attention to the thickness of copper foil when selecting copper foil, which is easy to ignore the influence of different types of copper foil roughness on the electrical properties of products. SEM analysis of the micro morphology of different types of copp... -
