摘要:
Conductive adhesive for checking electric circuits is formed on contact electrodes of a chip package or a multi-chip module. After contact electrodes of the chip package or the multi-chip module are set on terminal electrodes of a checking device in a correct position, the chip package or the multi-chip module is mounted on the checking device, so that the contact electrodes are electrically connected to the terminal electrodes with the conductive adhesive in-between, and thus the electric circuits of the chip package or the multi-chip module are checked.
