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 2 b is printed. Then the first PCB sheet 4a and the second PCB sheet 4b are coupled together by using an adhesive means 14.

The invention claimed is: 1. A device for coupling a PCB sheet, comprising: a blanked space forming part for forming a blanked space (S) by cutting away a defective circuit pattern part if any one of circuit pattern parts of a first PCB sheet is found be a defective circuit pattern part, and placing into said blanked space (S) of a second PCB sheet on which a good quality circuit pattern part is printed, and inserting PCB securing pins of a PCB securing plate into pin receiving holes so as to position-locate said first and second PCB sheets; a PCB securing means attached on said PCB securing plate, for preventing any loose movements of said first and second PCB sheets; a space formed between said first and second PCB sheets, for receiving an adhesive means into between said first and second PCB sheets which are secured on said PCB securing plate; and said adhesive means being filled into said space between said first and second PCB sheets to be cured so as to couple said first and second PCB sheets together. 2. The device as claimed in claim 1, further comprising a flat cover disposed on said first or second PCB sheet to protect the same. 3. The device as claimed in claim 1, wherein said second PCB sheet, on which a good quality circuit pattern part is printed, is fixedly inserted into said blanked space forming part and spaced at a predetermined gap from the same. 4. The device as claimed in claim 1, wherein said PCB securing means for securing said first and second PCB sheets on said PCB securing plate consists of PCB securing tapes. 5. The device as claimed in claim 4, wherein said PCB securing tapes are both-face tapes, and put around said first PCB sheet, said first and second PCB sheets and said PCB securing plate. 6. The device as claimed in claim 1, wherein said PCB securing tapes are heat resistant tapes for preventing thermal deformations. 7. The device as claimed in claim 1, wherein said space for coupling said first and second PCB sheets together forms a channel. 8. The device as claimed in claim 7, wherein a PCB securing tape is put to a bottom of said channel for preventing leakage of said adhesive means. 9. The device as claimed in claim 1, wherein said adhesive means filled into said space between said first and second PCB sheets is a high temperature adhesive for preventing thermal deformations. 10. The device as claimed in claim 9, wherein said adhesive contains a hardening agent added thereto. 11. The device as claimed in claim 1, wherein said space formed between said first and second PCB sheets for receiving said adhesive means has a width of 1 to 5 mm between said first and second PCB sheets. 12. A device for coupling a PCB sheet, comprising: a blanked space forming part for forming a blanked space (S) by cutting away a defective circuit pattern part if any one of circuit pattern parts of a first PCB sheet is found be a defective circuit pattern part, and placing into said blanked space (S) of a second PCB sheet on which a good quality circuit pattern part is printed, and inserting PCB securing pins of a PCB securing plate into pin receiving holes so as to position-locate said first and second PCB sheets; a PCB securing element attached on said PCB securing plate, for preventing any loose movements of said first and second PCB sheets; a space formed between said first and second PCB sheets, for receiving an adhesive element into between said first and second PCB sheets which are secured on said PCB securing plate; and said adhesive element being filled into said space between said first and second PCB sheets to be cured so as to couple said first and second PCB sheets together. 13. The device as claimed in claim 12, further comprising a flat cover disposed on said first or second PCB sheet to protect the same. 14. The device as claimed in claim 12, wherein said second PCB sheet, on which a good quality circuit pattern part is printed, is fixedly inserted into said blanked space forming part and spaced at a predetermined gap from the same. 15. The device as claimed in claim 12, wherein said PCB securing element for securing said first and second PCB sheets on said PCB securing plate consists of PCB securing tapes. 16. The device as claimed in claim 15, wherein said PCB securing tapes are both-face tapes, and put around said first PCB sheet, said first and second PCB sheets and said PCB securing plate. 17. The device as claimed in claim 12, wherein said PCB securing tapes are heat resistant tapes for preventing thermal deformations. 18. The device as claimed in claim 12, wherein said space for coupling said first and second PCB sheets together forms a channel. 19. The device as claimed in claim 18, wherein a PCB securing tape is put to a bottom of said channel for preventing leakage of said adhesive element. 20. The device as claimed in claim 12, wherein said adhesive element filled into said space between said first and second PCB sheets is a high temperature adhesive for preventing thermal deformations. 21. The device as claimed in claim 20, wherein said adhesive contains a hardening agent added thereto. 22. The device as claimed in claim 12, wherein said space formed between said first and second PCB sheets for receiving said adhesive element has a width of 1 to 5 mm between said first and second PCB sheets.
