Elimination of Hole Mouth Burr in Multilayer PCB Micro-Hole by Using Micro-EDM
The micro-hole is a key structure in multilayer printed circuit board (PCB), as it enables the effective transmission of electrical signals. At present, the most common way to machine PCB micro-holes is mechanical drilling using micro-bit. However, in the mechanical drilling of micro-holes, these ho...
