[0002] Flatness detection is sometimes also called frontality detection or coplanarity detection. The flatness detection system is specially used to detect the horizontal straightness, coplanarity, gap, pin width and other indicators of the pins of various IC chips, electronic connectors and other electronic components. Flatness detection is also required during the casting production process to ensure the quality and performance of the casting.

[0003] The existing method of flatness inspection of castings is to use a manual handheld detector to detect. During the inspection, the detector probe is brought into contact with the surface of the casting and the position of the detector is continuously adjusted to achieve multi-directional inspection.
