Abstract:
A method of producing high-frequency modules comprising:a first step of fabricating, on a master substrate, a plurality of sub substrates linked to connector regions at both ends of the master substrate, each of the sub substrates formed of substantially a rectangular shape and having an identical pattern of circuit developed thereon, providing on each of two side edges of the sub substrates, a set of signal terminals connected to a first circuit so that the set of signal terminals at each of the two side edges is formed integral with a set of signal terminals provided on a side edge of an adjacent sub substrate and is connected to a second circuit, and electrically isolating any two adjacent sub substrates from each other at their longitudinal end edges; a second step of, after said first step, mounting electronic components on each of the sub substrates; a third step of, after said second step, electrically isolating the signal terminals at each of the two side edges of the sub substrates from the signal terminals provided on the side edge of the adjacent sub substrate while the connector regions of the master substrate remain linked to the sub substrates; a fourth step of, after said third step, conducting an inspection with pins of an inspection tooling engaged in direct contact with the signal terminals of the sub substrates; and a fifth step of, after said fourth step, separating the sub substrates from the master substrate by cutting along the longitudinal end edges of each of the sub substrates.
