Saki’s BF-3Di is an automatic optical inspection (AOI) machine that not only performs inspection, but also provides measurements of each component for heights from 0 mm to 20 mm, with 1 micron height resolution.
Featuring an average takt time of just 18 seconds, the system is able to capture the most difficult defects, such as lifted leads, tombstones, reverses and height variations. The BF-3Di boasts a first pass yield higher than 95% or false-call rate of less than 100 ppm, and virtually zero escapes.
The proprietary offline programming software, BF-2 Editor software, fully emulates inspection conditions and provides real-time testing and verification of programming variables exactly as if the user were programming on the machine itself, thereby reducing programming and debug time and cost, while providing optimal inspection results.
Inspection data can be generated easily from CAD data in the same way as Saki’s 2D-AOI machines. As measurement is performed across a large area, a sample surface can be automatically detected and height zero reference points will be set automatically for each block area. By doing so, inspection library data can be easily added to necessary locations without being affected by adjacent components. The 3D machine also uses the same multiple-lighting technology as the 2D-AOI machines, and a variety of algorithms can be used based on the 2D-AOI experience.

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
