Abstract

A method and a device for coupling a PCB sheet are disclosed. If a defective PCB is found after the manufacture of continuously arranged circuit patterns, then the defective PCB sheet portion is removed to replace it with a new PCB sheet portion. That is, a defective circuit pattern sheet 2′ is removed from continuously arranged circuit patterns of a first PCB sheet 4a. After removal of the defective circuit pattern sheet 2′, the first PCB sheet 4a is position-located by means of a position locating means 12. Then the space which is formed by removing the defective circuit pattern sheet 2′ is filled with a second PCB sheet 4b on which a good quality circuit pattern 2b is printed. Then the first PCB sheet 4a and the second PCB sheet 4b are coupled together by using an adhesive means 14.
