[0002] An IC chip is a microelectronic device or component, which mainly integrates electronic components such as transistors, diodes, resistors, capacitors and inductors and wirings, and then writes a control program and data through an IC programmer to realize a micro-structure with circuit functions. An IC programmer refers to the process of providing a program for a programmed chip through programming needles. Since usually a printed circuit board (PCB) of a chip board is provided with multiple ICs, currently, one programmer is usually used to program one IC on a single board, and after programming one IC, another set of fixtures is required to manually flip the PCB and then program another IC. The working efficiency of the whole programming process is low and the cost is high. Content of the Utility Model
