Description

Technical Field

[0001] This utility model belongs to the field of crystal oscillator technology, and in particular relates to a high-reliability active crystal oscillator. Background Technology

[0002] An active crystal oscillator is a crystal oscillator with a built-in oscillation circuit that can directly output a stable and accurate clock signal. It is widely used in electronic devices that require high frequency accuracy and stability.

[0003] In the current crystal oscillator manufacturing process, adhesive is applied to a dispensing platform on a ceramic substrate, and then the wafer is mounted on the substrate. Subsequently, it needs to be placed in a tunnel furnace for thermosetting. The wafer is prone to displacement due to uneven heating of the adhesive dots. Moreover, after the adhesive dots are heated to the softening temperature, their fluidity increases, and they can easily climb up the wafer surface, affecting the final working efficiency and stability of the crystal oscillator. Utility Model Content

[0004] The purpose of this invention is to address the problem that in the production process of existing crystal oscillators, when adhesive is applied to a ceramic substrate and the wafer is then mounted on the substrate, followed by thermosetting in a tunnel furnace, the wafer is prone to displacement due to uneven heating of the adhesive dots. Furthermore, when the adhesive dots are heated to their softening temperature, their fluidity increases, making them prone to climbing along the wafer surface, thus affecting the final working efficiency and stability of the crystal oscillator. Therefore, this invention proposes a high-reliability active crystal oscillator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-reliability active crystal oscillator, comprising a ceramic base, wherein a plurality of dispensing platforms are disposed therein, a plurality of adhesive dots and a partition layer are disposed on the dispensing platforms, a plurality of limiting members are disposed around the dispensing platforms, and a quartz crystal is located on the dispensing platforms and is limited by the limiting members.

[0006] Furthermore, the aforementioned barrier layer is located on one side of several adhesive dots.

[0007] Furthermore, the aforementioned barrier layer is made of silicone oil.

[0008] Furthermore, the aforementioned limiting component includes a support plate and a limiting plate. The support plate is connected to the ceramic base via adhesive posts, and the limiting plate is connected to the support plate.

[0009] Furthermore, the aforementioned limiting plate is provided with guide posts, and the ceramic base is provided with guide grooves, with the guide posts suspended and connected within the guide grooves.

[0010] Furthermore, several limiting components are arranged at right angles around the dispensing platform.

[0011] This invention provides a high-reliability active crystal oscillator. It utilizes several dispensing platforms within a ceramic substrate, each platform containing adhesive dots and a barrier layer. Several limiting components are positioned around the dispensing platforms. When connecting quartz crystals, during subsequent tunnel oven heat curing, the limiting components guide the guide columns downwards along guide grooves as the adhesive columns soften, thus limiting the quartz crystals. Simultaneously, the adhesive dots soften and adhere to the bottom of the quartz crystals. The barrier layer, made of silicone oil, prevents the softened adhesive dots from climbing onto the quartz crystal wafer, improving the production quality and efficiency of the crystal oscillator.

[0012] Therefore, this embodiment has the following advantages compared to the prior art:

[0013] A high-reliability active crystal oscillator solves the problem that in the production process of existing crystal oscillators, adhesive is applied to a dispensing platform on a ceramic substrate, and then the wafer is installed on the substrate.

[0030] Specifically, see Figure 1-5 The barrier layer 4 is made of silicone oil.

[0031] This invention provides a high-reliability active crystal oscillator.

Several limiting components are positioned around the dispensing platforms.

The support plate 51 is connected to the ceramic base 1 via adhesive posts 7, and the limiting plate 52 is connected to the support plate 51. This allows the limiting plate to move downwards with the adhesive posts after they soften, preventing displacement of the quartz crystal and limiting its position.
