| titleOfInvention | A kind of manufacturing method of FPC micropore |
| abstract | The invention relates to a method for manufacturing FPC micro-holes, which comprises the following steps: drilling a cover film, falsely sticking the drilled cover film on the surface of the FPC that needs to be lasered at a temperature of 80° C. to 120° C. The FPC with the fake cover film is cold-pressed by the airbag machine, laser drilled, the cover film on the surface of the FPC after the laser drill is torn off, and then the plasma is removed to complete the production of FPC micro-holes. This method avoids direct laser light. The copper surface causes the hole to be blackened due to the residual laser toner; by increasing the cover film to increase the thickness of the medium layer through which the laser passes when the laser is drilled, and using the principle of spot weakening, the production of micro-holes with a diameter of less than 25um can be achieved. . |
