[0002] The production of high-precision test fixtures is extremely meticulous and demanding, among which microneedle insertion is the most critical, time-consuming, labor-intensive and difficult task. The smallest microneedle diameter in the current market can reach 0.04mm, and the minimum spacing of the pinhole arrangement can reach 0.1mm. Due to the small diameter of the microneedle, the high density of the pinhole arrangement on the fixture plate, the fixture plate is stacked in multiple layers with gaps between each layer of the fixture plate, and the size of each layer of the fixture plate and its hole position cause slight deviations due to processing, it is extremely difficult to complete the pin insertion work by direct observation with the naked eye.
