AOI System with scalable Resolutions

Saki 3Di22 January 2018 - The new 3Di Automated Optical Inspection (AOI) systems of Saki Corporation features high-speed (5,700mm2/sec), high-accuracy (XY positioning of 3µm at 3Ơ), height repeatability (below 2µm at 3Ơ), and scalable resolutions of 7, 12 and 18µm for boards weighing 12kg.

Saki's rigid gantry structure is a key component of the 3Di-LS2, 3Di-LD2, and 3Di-ZS2 hardware platforms. A dual-motor drive system, linear scale, and full closed-loop functionality provide machine accuracy and repeatability to generate absolute measurement data, which is essential for accurate machine-2-machine (M2M) communication. Saki's CoaXPress interface in the overhead camera captures images 1.7 times faster than previous models.

Also are Saki's 3D solder paste inspection (SPI) systems, the 3Si-LS2, 3Si-LD2, and 3Si-7µm. One common software platform supports all Saki 3D inspection systems - solder paste, optical, and x-ray--with an easy-to-program, intuitive software wizard. Auto-programming software significantly reduces library creation time, as libraries are automatically created using Gerber and CAD data. Algorithm-based software provides extensive programming capabilities, even for non-programmers. Saki's inspection data and default thresholds adhere to IPC standards.

Saki also introducied its new concept, Quality Driven Production, or QDP. QDP is a set of tools that ensures that the data and information that is communicated to third party systems is valid and accurate. It improves the stability of the process, while at the same time it increases productivity and minimizes the operating cost of the equipment. A self-diagnostic system with predictive and preventive maintenance management assures stable machine conditions and repeatable, consistent performance. Every key component is monitored along with system conditions, and a detailed diagnostic log is recorded. An optimized preventive maintenance plan reduces maintenance time, machine down-time, manpower, and costs.

The Multi Process View (MPV) on the BF2-Monitor shows the results of all inspection processes (SPI, pre-reflow, and post reflow) on one screen in real time for operator review, simplifying the verification process and making it less subject to error. It is also useful for analyzing the cause of a defective board.
