Utilizing the company's proprietary Scanning Moire Interferometry (SMI) 3D technology, the PPT861-SH inspection system from PPT Vision Inc. achieves 2D and 3D inspection scanning speeds of up to 125mm/s and examines strips of up to 40mm wide in a single scan.

The 122-by-91-by-166cm machine features a 3mm focusing depth, X-Y footprint of 205m, and a Z-axis resolution of 1.95m, making it suitable for small lots or high volume production applications.

SMI technology collects 3D data for all the balls and substrates on the entire strip in a single scan, and is claimed to enable improved coplanarity inspection speeds, accuracy, and robust performance surpassing traditional laser or camera-based 3D inspection systems.

The technology also provides a flexible platform for inspecting both grid and non-grid array devices.

All scanning parameters can be programmed to allow for the inspection of a variety of component sizes, lead counts, and package types including BGA, CSP, and LGA. Typical measurements include coplanarity, ball height, ball diameter, substrate flatness and true position.

The device performs inline or batch processing inspection while consuming 1kW. It operates from a 90Vac to 120Vac or 190Vac to 240Vac single-phase source, over the temperature range of 180C to 250C.

A built-in GUI is provided for straightforward system setup and operation, while an optional SECS/GEM interface allows the system to be integrated into the production process.
