Measuring the Coplanarity of PIN Pins with a Profilometer

PIN pins are widely used for electrical connection and signal transmission, such as those in relay terminals.If the coplanarity of PIN pins fails to meet requirements, the resulting unevenness will increase contact resistance, cause unstable current or signal transmission, and further affect the normal operation of the entire circuit or equipment.

PIN pins are small in size, with sharp and thin tips, and are mostly made of metal.Their highly reflective surfaces easily interfere with traditional optical inspection.The Shenshi Intelligent Laser 3D Profilometer can accurately detect tiny coplanarity deviations of PIN pins, including key parameters such as height and position, and reliably determine whether their coplanarity meets standards.This avoids misjudgment or missed detection caused by insufficient inspection accuracy, thus ensuring product quality.
