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.
Claims23
A system for coupling PCB sheets, said system comprising:
- a PCB supporting plate for supporting a first PCB sheet which has continuously arranged circuit patterns and from which a defective circuit pattern has been removed, and a second PCB sheet which comprises a good quality circuit pattern replacing the defective circuit pattern;
- PCB positioning means disposed upon the PCB supporting plate, for positioning said first and second PCB sheets side by side with a space in between;
- PCB securing means attached on said PCB supporting plate, for securing said first and second PCB sheets;
- and
- adhesive means for being filled into said space between said first and second PCB sheets so as to couple said first and second PCB sheets together when cured.
A system for coupling first and second PCB sheets, the first PCB sheet having at least an operative circuit pattern and at least a cut out from which a defective circuit pattern has been removed the second PCB sheet having an operative, replacement circuit pattern for the defective circuit pattern, said system comprising:
- a PCB supporting plate for supporting, on a top surface thereof, the first and second PCB sheets side by side;
- a PCB positioning element disposed on the top surface of said PCB supporting plate for preventing the first and second PCB sheets from moving in directions parallel with said top surface and for maintaining a space between the first and second PCB sheets being placed side by side on said PCB supporting plate;
- a PCB securing element attached on said PCB supporting plate and adapted to be attached to the first and second PCB sheets, for preventing the first and second PCB sheets from moving in a direction perpendicular to said top surface;
- and
- an adhesive deposited into the space between the first and second PCB sheets so as to couple the first and second PCB sheets together when said adhesive is cured.
In combination,
- first and second PCB sheets each having at least an operative circuit pattern and a plurality of holes;
- a PCB supporting plate supporting, on a top surface thereof, the first and second PCB sheets side by side;
- a plurality of pins extending upwardly from the top surface of said PCB supporting plate and inserted respectively into the holes formed in the first and second PCB sheets so as to prevent the first and second PCB sheets from moving in directions parallel with said top surface and to maintain a space between the first and second PCB sheets;
- PCB securing tapes disposed along a periphery of said PCB supporting plate, removably attached to and extending between a bottom surface of said PCB supporting plate and top surfaces of the first and second PCB sheets, thereby preventing the first and second PCB sheets from moving in a direction perpendicular to said top surface;
- and
- an adhesive deposited in the space between the first and second PCB sheets so as to couple the first and second PCB sheets together when said adhesive is cured.
