[0002] A single-chip microcomputer, also known as a single-chip microcomputer, is an integrated circuit chip. In a single-chip microcomputer, the chip is the core part of the microcontroller, integrating functions such as processor, memory, clock, input and output interface, etc. The operation and function realization of the microcontroller depend on the support and control of the chip.

[0003] However, the existing single-chip microcomputer structure is usually an integrated structure. Therefore, the chip inside the single-chip microcomputer cannot be replaced individually. When the chip inside the single-chip microcomputer is damaged due to various reasons, the traditional practice is to remove the entire single-chip microcomputer from the circuit board and then replace it with a new single-chip microcomputer. Such operation is not only cumbersome, but also requires professional technicians to perform, which is costly. At the same time, frequent disassembly and installation of the single-chip microcomputer may also cause unnecessary damage to the circuit board and other related components. Utility Model Content
