Description
Technical Field
The utility model relates to a syntonizer technical field, in particular to piece formula quartz crystal syntonizer.
Background
Quartz crystal resonators, also known as quartz crystals, commonly known as crystal oscillators, are resonant elements made using the piezoelectric effect of quartz crystals, which are used with semiconductor devices and resistive-capacitive elements to form quartz crystal oscillators. Quartz crystal oscillators are high precision and high stability oscillators widely used in various oscillating circuits such as color televisions, computers, remote controllers, and the like, and in communication systems for frequency generators, for generating clock signals for data processing equipment, and for providing reference signals for specific systems. Chip Mounted Devices (SMD) quartz crystal resonators are often used on integrated circuit boards, and generally include a base, a cover, and a quartz crystal. The chip quartz crystal resonator can be divided into a metal upper cover and a ceramic upper cover according to different packaging materials and modes. However, the metal upper cover needs electroplating and surface oxidation resistance treatment, and the ceramic upper cover needs to achieve thousands of high-temperature sintering cycle, so that the energy consumption is high, and the production efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a chip quartz crystal syntonizer solves the problem that current metal upper cover and ceramic upper cover manufacturing cost are expensive, production efficiency and product goodness are low.
In order to solve the technical problem, the utility model adopts the technical scheme that:

Detailed Description
The technical solution of the present invention will be described clearly and completely below with reference to specific embodiments of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the present embodiment provides a chip type quartz crystal resonator, which includes a base 1, a quartz crystal chip 5 and a cover plate 6, wherein the base 1 is provided with a groove 2 for installing and fixing the quartz crystal chip 5, two sides of the groove 2 are respectively provided with an electrode 3, two ends of the quartz crystal chip 5 are fixed on the vibrator 3 through silver paste 4, the cover plate 6 is a plastic chip cover plate 6, and the cover plate 6 is fixed on the base 1.
The cover plate 6 is a PPS cover plate, a PEEK cover plate, a LCP cover plate, a PBI cover plate, a PAI cover plate, a PEI cover plate, a PVDF cover plate, or a PTFF cover plate, or a common plastic cover plate. The cover plate is manufactured by extrusion and punch forming processes using plastic according to the shape and size of the cover plate 6. The method breaks through the limitation of metal and ceramic seal in the crystal industry, is lower than the existing metal and ceramic seal products in the manufacturing cost, does not need electroplating, surface antioxidant treatment and high-temperature sintering, has high production efficiency, low production cost, high finished product yield and environmental protection, and brings more choices for the chip crystal resonator.
the cover plate 6 is fixed to the base 1 by bonding with epoxy resin, silica gel or low temperature glass, or may be fixed to the base 1 by using other common adhesives.
