What problems are common during PCB fabrication?

　　　　When designing PCBs using software, we often encounter situations where components that appear connected (for electrical performance) are actually not. Therefore, following the correct order of operations is crucial when starting PCB fabrication based on the design file. Today, we'll focus on th

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
