[0023] In other implementation manners, there may be more grouping methods, as long as the distribution density of each group of conductive holes can be reduced after grouping, which will not be listed here.
[0024] Generally, before grouping the conductive holes opened on the circuit board, it can also include:
[0025] Conductive holes are opened on the circuit board, and copper sinking and electroplating are performed on the circuit board with conductive holes.
[0026] Among them, mechanical drilling or laser drilling can be used to drill holes in the circuit board, and then be processed according to the general copper sinking and electroplating process, so that a layer of metal is attached to the inner wall of the hole to achieve conduction and become a conductive hole.
[0027] After resin plugging the conductive holes, it can also include:
[0028] The excess resin on the surface of the circuit board is polished, copper sinking and electroplating are performed on the ...
