PCB perforation technology overview
The depth of the holes usually does not exceed a certain ratio (aperture). Buried holes are connection holes located in the inner layer of the PCB that do not extend to the surface of the PCB.

Evaluation of electroplated perforation performance of PCB board for 5G applications
The test circuits are based on a microstrip transmission line structure with a through-hole in the middle of the circuit used as a conductor and signal transition from the top copper layer of the dielectric substrate material to the bottom copper layer.
A brief history and development direction of PCB
Printed circuit board A flat plate made of non-conductive material, usually with pre-drilled holes designed to hold chips and other electronic components. The holes of the components help to connect the pre-defined metal paths printed on the surface of th
PCB manufacturing principle and production process introduction
The finger contains a number of exposed copper pads that are actually part of the PCB wiring. Usually to connect, we insert the gold finger on one PCB into the appropriate Slot on the other PCB (generally called an expansion Slot).
Analysis of reasons and countermeasures for PCB size expansion and shrinkage
