摘要： An oscillator that can suppress a solder crack caused by a temperature change by a simple structure at low cost and improve heat cycle resistance performance is provided. The oscillator includes an epoxy resin board and an electronic component mounted on the board. Two-terminal electrode patterns are formed on the board, and connected to terminal electrodes of the electronic component by solder. A projection is formed on each of the electrode patterns at a part connected to a corresponding terminal electrode to create a space between the terminal electrode and the electrode pattern, and the solder forms a fillet in the space. This contributes to enhanced adhesion strength of the solder.

摘要： Provided are an oven controlled crystal oscillator in which in a case where a metal lead is soldered to a substrate, even if cracks occur in the solder, its reliability is not reduced, and a production method. That is, an oven controlled crystal oscillator in which pre-tinning solders are formed around openings on a front surface and a rear surface of a substrate in which of a through hole for passing a metal lead therethrough is formed; and in a state where a metal lead including a solder layer (a pre-tinning solder) formed on its surface is inserted into the through hole of the substrate, the metal lead extending from the openings is soldered to the openings on the front surface and the rear surface of the substrate, so as to form a main solder, and a production method of the oven controlled crystal oscillator are provided.
