Description

technical field [0001] The invention relates to an electric resonator, in particular to an SMD quartz resonator and its processing equipment and method. Background technique [0002] SMD quartz crystal resonators are commonly used electronic devices, and their usage is increasing with the development of digital technology. But at present, SMD quartz crystal resonators have technical obstacles in improving processing efficiency and reducing production costs in terms of device structure itself and processing technology. [0003] The prior art SMD quartz crystal resonator structure such as figure 1 As shown, the metal coating 3 is first formed by printing a tungsten metal layer on the ceramic base 1 and then plating nickel and gold, and then sintering a silver-coated copper alloy Kovar ring on it in a high-temperature reducing atmosphere, and finally silver-coated copper The metal cover plate 2 is covered on the Kovar ring of alloy, and the metal cover plate and the ceramic b...

AI Technical Summary

Problems solved by technology

[0007] Parallel sealing welding technology is an evolution of spot welding technology. There are the following problems in the application of SMD quartz crystal resonator packaging: 1. The thickness of the metal material to be welded is required to be 0.1-0.25mm, which is difficult to reduce material costs; 2. In order to avoid When the electrode wheel touches the adjacent welding objects, the objects to be welded need to be arranged at a relatively large distance, which affects production efficiency and equipment size. For example, a processing pallet with the size of B4 paper can only carry about 300 pieces, which leads to various The processing machine is huge; 3. The surface of the seam welding electrode is prone to sticking damage, which will deteriorate the quality of the weld surface, and the electrode needs to be repaired regularly, which will affect the maintenance cost; 4. Spot welding must be used for positioning, which will affect the welding efficiency; 5. Spot fixing point Appropriate spacing is required, that is, there are size requirements for the object to be welded, which affects applicability

resulting in high production costs
