The production of Quartz Crystal Oscillator should include dozens of links, such as cutting, silver coating, dispensing, trimming, vibrating chip (active), and sealing etc, which requires a lot of manual participation. Just like an iron chain, the strength of which depends on the worst link, so we strive for perfection in every link. The following is the production process of YXC crystal:




1. Cutting: One of the important steps is the fixed angle. Due to the different angles of the quartz plate, its piezoelectric characteristics, strength characteristics and elastic characteristics are different, so the performance of the quartz crystal is different too. Firstly, we need to grind and cut on the quartz crystal rod. Then cut out the quartz wafer corresponding to this frequency. ( Quartz wafers have a one-to-one correspondence with frequency) The cutting angle determines the basic frequency deviation of the quartz crystal.


2. Silver plating: In order to improve the working accuracy, a layer of pure silver will be plated on the cutted quartz wafer.

3. Dispensing: Use silver glue (conductive glue) to fix the wafer on the base. The fixed angle determines the basic frequency deviation of the quartz crystal once again.

4. Testing: At this time, you can measure the output frequency of the quartz crystal with the testing equipment. During the testing, you can add silver again to make fine adjustments to improve the working accuracy.

5. Seal welding: If it is a passive crystal oscillator, it can be sealed with nitrogen. For an active crystal, you need to add a vibrating chip and seal it with nitrogen.

6. Sealing inspection: Check the product after sealing and welding to see if it has air leakage or not. Divided into rough leak detection and fine leak detection.

Rough leak detection: check for large leaks.

Fine leak detection: check for less leaks.

7. Aging and simulated reflow soldering: The product is subjected to high temperature and long-term aging, releasing stress and simulating trial environment of customer, exposing manufacturing defects to improve the reliability of shipped products.

8. Marking: Use laser to mark on the crystal shell, such as model and rated frequency, to distinguish different products.

9. Final testing: Test the electrical performance indicators of the finished products to eliminate defective products and ensure product quality.
