Description

Technical Field

[0001] The utility model relates to the technical field of fixtures, and more specifically to a PCBA board calibration fixture. Background Art

[0002] PCBA is a blank PCB board that has been mounted with SMT. Before the PCBA board is shipped, it needs to be calibrated and tested. When calibrating and testing the PCBA board, a fixture will be used to assist in positioning.

[0003] When clamping and fixing the PCBA board, the existing clamp usually directly uses the clamp arm to clamp and fix the PCBA board body. However, the power source of the clamp arm is generally a cylinder, an electric telescopic rod and a motor-driven bidirectional screw rod for operation, and there is no buffering structure. As a result, the clamp arm cannot buffer when contacting the PCBA board body, which easily causes damage to the edge of the PCBA board body. For this reason, we propose a PCBA board calibration fixture. Utility Model Content
