Embodiment 1

[0037] like figure 1 and 2 As shown, a plastic-encapsulated quartz crystal resonator, a plastic-encapsulated quartz crystal resonator, includes a cover plate 1, a quartz wafer 7, a conductive glue 9 and a base 2, and the cover plate 1 is formed by injection molding and can transmit light. A plastic cover plate, the cover plate 1 is provided with a groove 3 for accommodating the protrusion 4 on the base 2, the quartz wafer 7 is an electrode-plated quartz wafer 7, and the base 2 includes an opaque Plastic body and conductive pins, the opaque plastic body is provided with a housing chamber 8 for containing the quartz wafer 7 and a protrusion 4 corresponding to the groove 3, the conductive pins pass through the opaque plastic body The nano-injection molding process is combined, the quartz wafer 7 plated with electrodes is solidified in the housing chamber 8 through the conductive glue 9, and is connected with the conductive pins, and the cover plate 1 and the base 2 are fixed tog...

Embodiment 2

[0040] like image 3 and 4As shown, it is basically the same as Embodiment 1, the difference is that the crystal resonator is a three-pin quartz crystal resonator, and the three-pin quartz crystal resonator also includes a ground pin 11, and the ground pin 11 is arranged on three pin middle of the quartz crystal resonator. The power connection pin is a Z-shaped pin 5, and an injection hole is provided on the opaque plastic body corresponding to the Z-shaped pin 5. Setting the injection hole can ensure that the metal will not be deformed by the impact force of the plastic during injection molding, which can effectively improve product quality and yield. The injection holes can be set in different shapes as required, and square holes 10 are used in this embodiment.

Embodiment 3

[0042] like Figure 5 and 6 As shown, it is basically the same as Embodiment 1, the difference is that the crystal resonator is a four-pin quartz crystal resonator, and the four-pin quartz crystal resonator includes two power-connecting pins and two grounding pins Pin 11, the described electrical connection pins and grounding pins 11 are alternately arranged at the four corners of the four-pin quartz crystal resonator, and the described electrical connection pins can be in any shape, and the present embodiment is a square lead Feet 12.

Abstract

The invention relates to a plastic-packaged quartz crystal resonator shell comprising a cover plate and a pedestal, wherein the cover plate is a plastic cover plate, the pedestal comprises a plastic main body and conductive pins, an accommodating chamber for accommodating a quartz wafer is arranged on the plastic main body, the conductive pins and the plastic main body are combined together via ananometer injection molding process, and the cover plate and the pedestal are fixed together to seal the quartz wafer. The cover plate can be the light-permeable plastic cover plate, grooves for accommodating bumps on the pedestal are arranged in the periphery of the cover plate, the pedestal comprises the plastic main body and the conductive pins, the plastic main body is provided with the accommodating chamber for accommodating the quartz wafer and the bumps corresponding to the grooves, the plastic main body is not light-permeable, and the cover plate and the pedestal are fixed together vialaser welding to seal the quartz wafer. The product provided by the invention breaks the limitation of sealing of metal and ceramic in the crystal industry, and more selectivity is provided for the products used by the customers.

Description

technical field [0001] The invention relates to a plastic packaged quartz crystal resonator and a preparation method thereof, belonging to the field of quartz crystal resonators. Background technique [0002] Quartz crystal resonators are widely used in various systems such as global positioning system (GPS) and mobile communication. Quartz crystal resonators are packaged in metal and ceramic, meeting the light, thin, short, and small requirements of portable products represented by mobile phones. The packaging of quartz crystal resonators has changed from traditional bare metal shells to those covered with plastic metal and ceramic packages. change. The traditional crystal resonator ceramic package includes at least 2 layers of ceramic substrates, and a cover fixed to the ceramic substrates. The inner ceramics are provided with internal electrodes, and the outer ceramic substrates are provided with external electrodes. The internal electrodes and the external electrodes ar...
