Problems solved by technology

In the tuning fork chip processing technology, the length of the chip is shortened, which will inevitably make the width of the tuning fork chip thinner, and the design and production accuracy of the finer tuning fork chip becomes difficult. The production of traditional tuning-fork wafers with small pedestals requires the introduction of expensive photolithographic etching processes

Embodiment Construction

[0018] Control attached figure 2 , T-shaped tuning fork chip, its appearance is T-shaped, the longitudinal part of T-shaped is the chip tuning fork arm part, the transverse part of T-shaped is the chip terminal part, and D is the dispensing part between the chip and the ceramic base.

[0019] The design method is that the tuning fork arm of the T-shaped tuning fork chip remains unchanged, that is, the length of the chip tuning fork arm is 2.1-2.3 mm, the width of the chip tuning fork arm is 0.2-0.25 mm, and the terminal part of the tuning fork chip is horizontalized to reduce The length of the chip terminal length B, thereby reducing the overall length of the tuning fork chip, that is, the chip terminal length B is reduced to 0.2-0.3mm, the width range of the chip terminal is increased to 1.3-1.5mm, and the total length of A+B is controlled at 2.3-2.6 mm, the overall size is 2.3mm×1.3mm-2.6mm×1.5mm.

[0020] The appearance of the T-shaped tuning fork chip is T-shaped, which ...

Abstract

The invention relates to a T type tuning fork wafer and a design method thereof. The T type tuning fork wafer is characterized in that the external form of the tuning fork wafer is in a T shape; and the longitudinal part of the T shape is a wafer tuning fork arm part; and the horizontal part of the T shape is a wafer terminal part. A dispensing part is formed between the wafer and a ceramic pedestal. The design method comprises: (1), the length A of the wafer tuning fork arm is 2.1 to 2.3mm; (2), the width C of the wafer tuning fork arm is 0.2 to 0.25 mm; and (3), lateral processing is carried out on the terminal part of the tuning fork wafer. The advantages are as follows: a tuning fork wafer that is easy to process can be arranged inside a paster type ceramic pedestal conveniently; and the design and production of the low-cost miniaturization clock device can be realized.

Description

technical field [0001] The invention relates to a T-shaped tuning fork wafer and a design method applied in the field of design and manufacture of quartz crystal electronic components, and belongs to the technical field of production of quartz electronic components. Background technique [0002] With the rapid development of electronic information technology, the requirements for frequency components are becoming higher and higher. As a kind of frequency components, real-time clock (RTC) devices are showing a trend of miniaturization and thinning, and with the gradual increase in demand, processing costs are also facing greater challenges. The role of the RTC device is to generate a sequential circuit reference signal. There are many types of RTC products, which can be generally divided into two types: built-in crystal and external crystal according to the product structure. Generally, the cost of RTC with an external crystal structure is low, but some problems are often e...
