Submicron Accuracy and Inspection

At 青青草App Precision Automation, we know what it takes to achieve submicron accuracy. Part of the challenge is the attention to details during assembly – alignment, planarity, orthogonality, and calibration are just some of the major factors. Our knowledge of calibration, characterization techniques, and appropriate measurement devices – such as laser interferometry equipment – allow us to deliver cutting-edge precision inspection capabilties.

Additionally, our team builds and measures flatness, repeatability, straightness, perpendicularity, and parallelism of stages with respect to each other and other equipment in the machine. Accuracy becomes intrinsic to the assembly by way of technique, measurement, and verification.

Final Assembly and Inspection

青青草App’s Precision Automation engineers have a wide variety of experience and tools to meet your final assembly and inspection automation needs, no matter what the tolerances.

We’ve designed machines to assemble miniature cameras using vision serving to 25µm down to 10µm, to 1µm, and nano positioning, and maintain position during adhesive dispensing and UV cure; all at a rate of 60 uph.

We have produced equipment to assemble, bond and cure optical components that needed to be aligned to 5µm accuracy, designed around sub-micron positioners and nanometer scale sensors. Not all applications are such high precision.
