Abstract
Electronic devices are provided with a high-frequency circuit board and a coaxial connector connected to external high-frequency signals to the circuit board. The lead terminal of the coaxial connector is directly soldered to a land on the circuit board to enable high-frequency signal transmission. The fixing portion, which is on one side of the circuit board and apart from the coaxial connector, has a structure such that the horizontal tension of the circuit board is relaxed. In this mounting method, repetitive tension due to differences in linear expansion coefficient does not act on the soldered portion.
