New high-speed AOI from Yamaha SMT is released

 Yamaha SMT announces that March 1st, 2024, they will release a new high-speed AOI - the YRi-V TypeHS - a 3D hybrid AOI system, that achieves both highest speed & precision in SMT inspection in any SMT line

New AOI innovation

The new high-speed AOI is 1.6 times faster & has a 25-megapixel high-resolution camera

YRi-V TypeHS has significantly improved image processing capability by adopting a high-resolution 25-megapixel camera, which is more than twice that of previous models, and the latest high-performance CPU and GPU applications. As a result, high-definition inspection with resolutions of 7 μm and 5 μm is approximately 1.6 times faster than previous models, making the new model one of the fastest in the industry*.

In addition to the conventional high-precision 8-direction 3D projector, a high-performance 3D line laser has been newly installed. By combining this with 3D projector images using the phase shift method, it is now possible to reproduce the shapes of specular and transparent components more accurately, further improving inspection capabilities.

This provides greater accuracy in detection capability for 008004" (0201 = 0.25mm x 0.125mm) sized ultra-small chips and specular-glossy components, further contributing to improved quality in module & device PCB production.

* 3D inspection speed 16.2 cm2/s with resolution 5 µm (Company optimal conditions when using 4 projectors: According to Yamaha Motor research as of January 18, 2024)

Product outline & Market background

The Yamaha YRi-V TypeHS is created for the future

The reliability shown with SMT processes directly affects the market value of the products. The SMT field in recent years has seen the shift toward smaller sizes, higher densities, greater functionality, and more diversifications accelerate rapidly, and faster yet more precise inspection across all items by AOI systems will be even more sought after. 

Also more recently, the use of thin and extremely small WLCSPs and FOWLPs*, which have specular gloss on the package surface, has risen significantly in the market. So, in addition to specular components that are difficult to inspect, the need for compatibility to mount ultra-small chips at narrow pitch is dramatically increasing.

In response to these market changes and demands, the YRi-V being developed and released in July 2021, Yamaha SMT has produced an AOI system that still is extremely fast and highly accurate, achieving accurate detection even for 008004" (0201) sized ultra-small chips and specular glossy components.
