3D Technology-Automated Optical Inspection Equipment

SPI

INSUN SPI is used after the printing process to check for solder paste volume, Area, Height, Shape,Shift, Bridge, Overflow. SPI is also used in the printing test set-up to review the stability of the production process.


3D SPI technology-Automated Optical Inspection Equipment
INSUN SPI using optical principle and triangulation method to check the state of solder paste printing and accuratedly analyze the defects, the core technology is Phase Modulation Profile Measurement(PMP), also known as Phase Shift Profilometry(PSP),  is a method based on sinusoidal grating projection, which obtains multi-deformed light field images by discete phase shift, calculates phase distribution according to multi-step phase shift method, and finally obtains high-precision volume measurement results by geometric methods such as triangulations.

N-step phase-shifting algorithm based on white-light moire fringes can provide detection accuracy of 1um level (height resolution 0.37um, 8 bit grayscale) , and two grating heads can deal with reflection and shadows easily.

The advantages of INSUN SPI technology:
♦ Digital structure grating systems, can deal with reflection and shadow effectively, and to avoid late maintenance costs
♦ Based on PMP technology, to achieve high-precision detection as 0.37um hight resolution and 1um accuracy level.
♦ 2D/3D true color display
♦ Easy programming, just 5~10 minutes. and support offline programming function.
♦ Warp page/Z axis dynamic compensation function
♦ Close loop function with printer machine.
♦ Badmark recgonition.
♦ Powerful SPC report function.
