FPC manufacturer tells you what is FPC board drilling through holes
As the FPC manufacturer knows that, the through-holes of flexible printed boards can also be drilled by numerical control like rigid printed boards, but they are not suitable for a hole processing of double-sided metalized a hole circuits in tapes. With the increase in the density of circuit patterns and the smaller diameter of metalized holes, coupled with the limitation of the diameter of CNC drilling, many new drilling technologies have been put into practical application. These new drilling techniques include plasma
Body etching, laser drilling, punching with small apertures, chemical etching, etc., these drilling technologies are easier to meet the hole forming requirements of the tape process than CNC drilling.
