Embodiment Construction
[0028] The present invention is a crystal oscillator with a layout structure for miniaturized size, which can be used in the layout of quartz clock crystal oscillators, programmable quartz crystal oscillators, voltage-controlled quartz crystal oscillators and temperature-compensated quartz crystal oscillators structure, when the circuit layout is performed, the electrical contacts of the patterned circuit are symmetrically concentrated from the outside to the center of the first groove, and the electrical contacts are located under the crystal oscillator integrated circuit, so it can be used in a limited platform space In this way, the flexibility of circuit layout can be improved, so the first groove can free up enough layout space, and the pattern of at least two patterned electrical units can be expanded to the maximum, while increasing the crystal oscillator in the process The area of the pattern required for testing the piezoelectric element is improved, thereby improvin...

Abstract
The invention provides a crystal oscillator equipped with a layout structure aiming at a miniaturization size, at least comprising a platform possessing first and second grooves, a plurality of internal leads arranged in the interior of the platform, a crystal oscillation integrated circuit connected with the internal leads and a plurality of patterned circuits arranged in the first groove, wherein the electrical connecting points of the patterned circuits are symmetrically concentrated in the center of the first groove from exterior, so that the first groove can have enough layout area, and the patterns at the other ends of patterned electrical units can be expanded to maximization to solve the problem that the package and test qualified rate are bad when the conventional crystal oscillator layout is carried out miniaturization. In addition, the crystal oscillator equipped with the layout structure aiming at the miniaturization size of the invention enables the relative distance of the crystal oscillator integrated circuit pins to be shortened, and for a platform needing flip chip, the parallelism demand of the platform can also be reduced.
Description
technical field [0001] The invention relates to a piezoelectric device, in particular to an oscillator piezoelectric device. Background technique [0002] Using quartz crystal piezoelectric elements as oscillators is currently the most accurate and stable oscillator. The International Electrotechnical Commission (IEC) divides quartz crystal piezoelectric element oscillators into four categories: quartz clock crystal oscillators (Simple Package Crystal Oscillator, SPXO), Voltage Controlled Crystal Oscillator (VCXO), Temperature Compensated Crystal Oscillator (TCXO), Oven Controlled Crystal Oscillator, OCXO ), with the vigorous development of the electronics industry, electronic products have entered the research and development direction of multi-function, high performance and light weight. In order to meet the packaging requirements of high integration and miniaturization of semiconductor chips, the past circuit layout methods are no longer sufficient. Use, the existing osc...
