Circuit boards are made up of layers of copper foil circuits connected by vias, including Plating Through Holes (PTH), Blind Via Holes (BVH), and Buried Via Holes (BVH), with different methods and costs for conducting electricity and maximizing space utilization in PCB prototyping.
The text discusses the removal of unused via pads to reduce drill bit tear and the impact on copper.
What level of clearance is necessary for a via hole or barrel with no pad to copper? Read More »
PCB manufacturing involves surface solder mask and plugging. Requirements for via hole plugging technology and the need for plug holes in SMT and BGA PCBs are essential as the electronics industry develops.
