Addressing High Precision AOI Challenges by CyberOptics at SMTA South East Asia Technical Conference
Todd Liberty, a 15-year veteran of CyberOptics, presented a topic on ‘Addressing High Precision Optical Challenges with Unique 3D Technology Solution” at the SMTA South East Asia Technical Conference in Penang last month. The 30-minute presentation was well-received by the audience.
SMTA South East Asia Technical Conference took place on April 14-16, 2015 at the Eastin Hotel in Penang, Malaysia.
Driven by the continued decrease in the size of electronics packaging, combined with the increase in density, there is a critical need for highly accurate 3D inspection for defect detection. Using multi-view 3D sensors and parallel projection, it is possible to capture more of the board at a faster rate as compared to serial image acquisition, which is more time-consuming. Precise 3D image representation can then be generated using sophisticated fusing algorithms that take the multiple captured images and fuses them into one precise 3D image.
The result is high-speed 3D inspection.
Multi-reflection suppression (MRS) technology enables highly accurate 3D measurement by meticulously identifying and rejecting reflections caused by shiny components and reflective solder joints. MRS algorithms use a very rich data set from multiple cameras at every location.
Combined with sophisticated algorithms that fuse the image data from multiple cameras, multiple reflections are effectively suppressed. This technology is a key building block for achieving high accuracy at production speed in an automated optical inspection (AOI) system.
