The TR7700Q 3D AOI has a digital four-way fringe light projection technology, combined with the latest 2D 3D detection technology, which has set off a new revolution in the field of assembled circuit board detection. The omnidirectional 3D digital stripe light technology covers a wide range of detection, and has excellent accuracy to show minimal coplanar defects and solder joint problems. TRI's 3D tin spot and tin climbing detection meet IPC standards to ensure the quality of tin climbing. By checking the tin climbing height and volume, the TR7700Q 3D AOI can detect such undesirable phenomena as lack of tin, lack of tin and empty soldering.
