| titleOfInvention | A kind of print circuit plates making method |
| abstract | A kind of print circuit plates making method, for shortening the printed circuit board (PCB) manufacturing cycle, reduce the pollution during printed circuit board (PCB) manufacture produces, it is characterised in that including at least following steps：Substrate is carried out to cut；Plate face roughening of copper foil is handled, corrosion forms internal layer circuit, and circuit dry film photoresistance is removed；The internal substrate of shaping and outer-layer circuit copper foil are binded, for extended circuit scale；The copper foil of outer layer is corroded, and forms outer-layer circuit；Interlayer conduction hole and element fixing hole are drilled out on interlayer circuit, for connecting internal layer circuit and outer-layer circuit；The copper facing on hole wall after interlayer conduction hole forming, for completing circuit turn-on；Add protective layer at the tag contact of circuit board, for preventing end points from producing oxide in use；Text information is marked on circuit board top layer, and design drawing is provided. |
