Description

Technical Field

[0001] The utility model relates to a mounting jig applicable to a probe card. Background Art

[0002] A probe card is a test interface mainly for testing bare chips, which is composed of probes, electronic components, wires and a PCB (printed circuit board). The probes on the probe card contact the chip to lead out the chip signal, and then cooperate with peripheral test instruments and software control to achieve the purpose of automatic measurement. Since the probes are easily damaged during daily use, such as the tip parts of the probes becoming blunt, they need to be polished and repaired. Since the probes are very small, a needle adjustment machine is required for maintenance. The needle adjustment machine consists of three major modules: a stage, a glass bracket for fixing the needle card diaphragm, and a microscope. Among them, the stage is a circular disc with vacuum suction. When the probe card needs to maintain the needle position, a jig is required to fix the needle card, and then place it on the disc to keep the needle card stationary. The direction of the disc is adjusted through the XYZ axes, and the position of the needle tip is manually adjusted through the corresponding needle card diaphragm alignment under the microscope.

[0003] After retrieval, the patent: A processing jig for a probe card (CN202021487516.0), includes a base, a fixing seat, a first clamping mechanism, a second clamping mechanism, a side clamping mechanism and a plurality of driving mechanisms. A fixing groove is provided in the middle of the fixing seat. The plurality of driving mechanisms are respectively used to drive the first clamping mechanism, the second clamping mechanism, and the side clamping mechanism to move towards the inside or outside of the fixing seat. When the present utility model is in use, the PCB substrate is installed inside the fixing groove, and the first clamping mechanism, the second clamping mechanism, and the side clamping mechanism are driven by the driving mechanisms to fix the four sides of the PCB substrate to prevent it from shifting during the processing. The above structure prevents shifting, but it is not convenient enough to operate, which affects the work efficiency.
