Scanning the Edge Thickness of a Circuit Board March 2, 2021 – Posted in: Thickness Measurement

In this application, we're going to be using the Acuity AP820-5 laser line sensor for scanning edge thickness of a circuit board. The AP820 laser profiler has a five millimeter depth of field in the Z direction, and a four millimeter wide laser line sensor. With this model, we should have a linearity of about plus or minus 3.5 microns of accuracy, which equates to about a pixel roughly every seven microns. In our demo… Continue reading
