Two Causes of Electroplating Imperfections and How to Improve Them

　　With the rapid development of the PCB industry, PCBs are gradually moving towards high-precision fine lines, small hole diameters, and high aspect ratios (6:1-10:1), requiring 20-25µm of copper penetration at the holes. For boards with a line spacing of ≤4µm, electroplating imperfections are a com

Precision Overlap Issues in Multilayer Blind/Buried Circuit Boards

　　　　Multilayer blind/buried and blind via printed circuit boards (PCBs) are generally manufactured using a "separate board" production method. This means that multiple pressing, drilling, and via plating processes are required to complete the process, making precise positioning crucial.　　High-precis
