| titleOfInvention | Printed wiring board manufacturing method |
| abstract | The present invention provides a method of manufacturing a printed wiring board, which can meaningfully prevent an intrusion of a chemical solution into an interface between a carrier and an extremely thin copper layer in a step of forming a build-up wiring layer, and can meaningfully suppress a coreless support Partial cracking of the very thin copper layer in the separation step and the resulting defects. The method of the present invention comprises the steps of: preparing a carrier copper foil with a product Wc × Pc of a product width Wc × Pc of 20 to 50 μm in the surface of the release layer side of the carrier; Or forming a build-up wiring layer on the ultra-thin copper layer to form a build-up layer with the build-up wiring layer, and separating the build-up layer of the build-up wiring layer on the peeling layer to obtain a multilayer wiring board including the build-up wiring layer The step of processing the printed wiring board by processing the multilayer wiring layer. |
