Embodiment Construction

[0006] The present invention will be further described below in conjunction with embodiment.

[0007] Firstly, the sintered non-plated base is electroplated into a tin-copper high-temperature-resistant base, and the punched non-plated shell is electroplated into a nickel-plated high-temperature resistant shell, and the tuning fork-shaped chip is welded on the high-temperature resistant shell by melting the high-temperature 300-degree solder with a hot air gun. On the support with a high temperature of 260 degrees, the tuning fork type wafer is adjusted to the frequency point required by the tuning fork type crystal through the frequency modulation process, and then the product is formed by SMD packaging after sorting through the 120 degree high temperature aging process.

Abstract

The invention relates to the field of crystal resonators, and discloses a process for producing a tuning fork quartz crystal resonator. The process comprises the following steps of: electroplating a sintered substrate which is not electroplated to obtain a tin copper high-temperature-resistant substrate, electroplating a stamped shell which is not electroplated to obtain a nickel-plated high-temperature-resistant shell, melting high-temperature-resistant soldering tin by using a hot air gun to weld a tuning fork wafer on a high-temperature-resistant support, adjusting the tuning fork wafer to the frequency point which is required by the tuning fork wafer by a frequency adjusting process, sorting by a high-temperature aging process, and performing surface mount type packaging to obtain a product. Due to the adoption of the technical scheme, the using range of the tuning fork quartz crystal resonator is widened.

Description

technical field [0001] The invention relates to the field of crystal resonators, and relates to a production and preparation process of a tuning fork type quartz crystal resonator. Background technique [0002] The original tuning fork type quartz crystal resonator cannot withstand high temperature due to reasons such as bracket, shell and production process. range is limited. Contents of the invention [0003] The object of the present invention is to provide a tuning-fork type quartz crystal resonator used in normal temperature and high temperature environment and its production preparation process. [0004] The technical solution of the present invention is: first, electroplate the tin-copper high-temperature-resistant base by sintering the base without electroplating, electroplate the stamped shell without electroplating into a nickel-plated high-temperature resistant shell, and melt the high-temperature-resistant solder with a hot air gun. The chip is welded on the ...
