PURPOSE:To protect the internal circuits of the electronic device electrically by a method wherein a conductive self-adhesive thin film provided with ramifications adhering to terminals of the device at a delivery time and the trunk of thin film part is grounded is stripped off after an installation wiring and just before an operation test. CONSTITUTION:A well-known conductive self-adhesive tape 5 is provided with branches 5B ramified from a trunk part 5A with the intervals corresponding to those of external terminals 7 of an electronic device 6. These branches adhere to the terminals 7 on the side of the wiring within a board of the device 6 at a delivery time and the trunk part 5A is grounded 8. After completing an installation wiring and just before an operation test, the tape 5 is removed. In this constitution, even if a serge voltage caused by static electricity or induction is generated, it is removed through the cnductive tape and the minute internal circuit can be protected. |
