100% Optical Inspection

4 Six Sigma

We aim to be one of the zero PPM fastener suppliers in the world. Currently, 4 Six Sigma or 63 PPM with 1.33 Ppk is where we are. We work with our suppliers upstream to review SPC. Also, we conduct MSA on our suppliers' optical equipment and work with them to solve technical problems, such as part orientation to enable full automation and zero damage within the optical inspection.

+-0.264mm & +- 2um

For 100% optical inspection, the dimensions we measure are +-0.264mm. It mainly serves as catching missing parts on fasteners and low-tolerance dimensions. Our randomly selected inspection for critical dimensions performs on a Keyence IM series with +/- 2um. We also use gauges to inspect other functional dimensions.
