An adaptor for inspection of circuit boards includes a wiring board for connection, on a front surface of which a plurality of connecting electrodes are formed correspondingly to electrodes to be inspected, and an anisotropically conductive elastomer sheet detachably arranged on the front surface of the wiring board for connection. In the method, a protective film covers a switching device, and a contact hole is defined at the protective film in such a manner to expose one electrode of the switching device. The tape assembly is gathered onto a reel and loaded into a receiver wherein stent-bearing tape is fed into an automated tape separator, and stents removed from the tape assembly are automatically mounted onto holders, which pass the stents through a coater. A coupling element surrounds the radiating strips and a dielectric layer is sandwiched between the patch element and the radiating strips.
