Key Features & Benefits

The 3D Solder Paste Inspection Machine:

3D Solder Paste Inspection Machine (3D SPI) is a SMT testing device that calculates the solder paste height printed on PCB board by triangulation method based on optical principle.

The double digital projection grating structure ensures that the effective visual field of the product is not disturbed by shadows; 5MP high-speed plane array camera and telecentric lens are used to ensure the extremely high image quality and effect; The real color image and analog image function are used to detect the 3D quality of solder paste and red glue process; To support the data import of Gerber, CAD and other formats, The programming is fast and easy, average 5~10min.
