ABSTRACT:
An electronic device is interposed between a pair of contact units of a contact probe unit without using any soldering or other permanent connecting arrangement. Alternatively, the electronic device is interposed between a securing plate and a contact unit provided with a pair of arrays of contact modules. Thus, the electronic device may be incorporated in the contact probe unit without requiring any permanent connecting arrangement such as soldering which may produce any contaminants or other undesirable substances or cannot be readily detached and attached. This is particularly important in a clean room environment. According to a preferred embodiment of the present invention, said electronic device comprises an integrated circuit mounted on said sheet member. For instance, the electronic device may consist of a TAB for driving an LCD panel so that the LCD panel may be tested in a realistic condition.
