Manufacturing method of printed wiring board and a laminate jointing apparatus

Abstract

This invention provides a manufacturing method of printed wiring board which enables a plate-like substrate to be carried and processed without any contact to its product surface. End portions of plate-like copper clad laminates are overlapped vertically and then joined linearly by rotating an ultrasonic horn along the end portions. Consequently, copper foils can be metal-joined and a joining strength necessary for transportation with a roller is obtained. Because belt-like copper clad laminate is obtained by joining the plate-like copper clad laminates and after that, processed, thus, the belt-like copper clad laminate can be carried without any contact to its product surface as it is carried with the roller, and then processed.

1 . A laminate joining apparatus comprising:
 a positioning device configured to position end portions of plate-like laminates each in which metal foil is laminated on a resin layer thereof into contact with each other at a contact portion; and   a joining device configured to use a disc-like ultrasonic horn to linearly join the plate-like laminates along the contact portion so as to obtain a long laminate.   
     
     
         2 . The laminate joining apparatus according to  claim 1  wherein the positioning device comprises a carrying unit. 
     
     
         3 . The laminate joining apparatus according to  claim 1  further comprising a support base configured to support the plate-like laminates. 
     
     
         4 . The laminate joining apparatus according to  claim 3  wherein the disc-like ultrasonic horn is coupled to the support base such that the disc-like ultrasonic horn rotates along the end portions of the plate-like laminates in contact with each other. 
     
     
         5 . The laminate joining apparatus according to  claim 1 , wherein the positioning device comprises a positioning plate configured to position the plate-like laminates such that the side ends perpendicular to the end portions to be joined are in a straight line. 
     
     
         6 . The laminate joining apparatus according to  claim 2 , wherein the positioning device comprises a positioning plate configured to position the plate-like laminates such that the side ends perpendicular to the end portions to be joined are in a straight line. 
     
     
         7 . The laminate joining apparatus according to  claim 3 , wherein the positioning device comprises a positioning plate configured to position the plate-like laminates such that the side ends perpendicular to the end portions to be joined are in a straight line. 
     
     
         8 . The laminate joining apparatus according to  claim 1 , further comprising a roller configured to carry the plate-like laminates in a joined state. 
     
     
         9 . A laminate joining apparatus comprising:
 means for positioning end portions of plate-like laminates each in which metal foil is laminated on a resin layer thereof into contact with each other; and   means for linearly joining the plate-like laminates along the contact portion so as to obtain a long laminate.
