| titleOfInvention | A kind of manufacture craft of the fine and closely woven route of IC support plate |
| abstract | The invention discloses a kind of manufacture crafts of fine and closely woven route of IC support plate, comprising the following steps: firstly, drilling to plate to be processed；Then, to the plate electro-coppering to be processed after drilling, by the via hole；Then, dry film is pasted to the entire plate to be processed after plating；Then, the land for the plate to be processed for posting dry film is exposed；Then, develop to the logicalnot circuit region not being exposed, remove the dry film in logicalnot circuit region, and etch away the copper face in logicalnot circuit region；Then, the dry film of land is removed after the copper face for etching away logicalnot circuit region；Then, ablation is carried out by copper face of the laser to fine and closely woven land on the plate to be processed；Then, quick microetch is carried out to the copper face after ablation.This method modifies route by laser ablation and quick microetch, therefore can make line width in 40um and following route, and easy to operate. |
