High-precision clock chip compensation production system and method

Abstract

The invention provides a high-precision clock chip compensation production system and method. The system comprises a PC, a master control software module, a first-stage master control unit, a second-stage master control unit, a third-stage master control unit set module, a frequency measurement unit set module, a reference clock source module, a chip DUT bottom plate module and an incubator module. The third-stage master control unit set module comprises a plurality of third-stage master control units; the frequency measurement unit set module comprises a plurality of frequency measurement units; a plurality of chip DUT devices are arranged on the chip DUT bottom plate module; and the chip DUT bottom plate module is arranged in the incubator. According to the scheme, the production system is low in cost, high in precision and good in expandability, and the production efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to the field of testing, compensation and production of real-time clock chips, and in particular to a high-precision clock chip compensation production system and method. Background technique [0002] In various applications, clock timing is a common function. In most cases, a chip that provides a clock is used, and the standard output frequency is 32.768kHz. It is used in the following occasions, such as consumer electronics, industrial communication, meter grid, base station, counting and timing, etc., and the application environment is relatively harsh. However, the output frequency of the clock chip is generally not absolutely accurate, it always fluctuates around the standard 32.768kHz, and it is related to the change of temperature. At a slightly lower or higher temperature, the output frequency of the clock chip drifts seriously, and the consistency is poor, which makes it...

Problems solved by technology

When processing the production data of several clock chips, the time consumed is still within an acceptable range; but when processing the production data of tens of thousands of clock chips, this manual method is seriously inefficient and takes a lot of time
