1 Product Overview and Features

1.1 Product Overview

This product is Benchtop high-speed Automated Optical Inspection system that acquire detail image of a
PCB in one pass by using a line scan sensor camera and store all information embedded in the images in
a computer memory to conduct high speed inspection and judgement by employing Saki original image
processing technology.
BF-Sirius can be used in any stage of PCB manufacturing process from manual mounting to automated
post-print, post-mount, as well as post-flow / reflow inspections.

1.2 Features

1.2.1 System Structure

• This is compact and easy to use Benchtop High Speed Automated Optical Inspection system.
The machine equipped with newly developed CCD camera and illumination lighting to realize high
throughput for scan of L size board (460 (W) × 500 (L) mm) within approximately 10 seconds.
• The clearance of PCB from 40 mm for top side and 60 mm for bottom side is newly designed to
enable handling PCBs mounted with very tall components. Even if the PCB warpage is approximately
2 mm, top side clearance still allows 38 mm component height from PCB surface.

1.2.2 Lighting and Image Acquisition

• Switching between three different LED lighting,
Light, and LowLight, enable acquiring three kinds of the images only in one pass.
• By using line sensor camera, the system achieve high definition images of
• Shading technology compensates image brightness automatically so that it will always be under
the same conditions.
• The telecentric lens optics increases inspection accuracy. By this accuracy improvement, virtually
distortion free images can routinely be acquired.

1.2.3 Expanding Whole Board Image on Memory

• With line scan technology, image data of entire board can be stored in the memory, rather than
partial area images, and therefore all essential operations including inspection data creation,
judgement with algorithmic routines, can be implemented at very high speed, effectively shortening
tact time.
• Image data once stored in memory are kept until the next image is scanned, so there is no need
to rescan the image everytime for edition, or inspection purposes.

1.2.4 Inspection Data Management with Inspection Library

• Image can be acquired with exact same illumination conditions anywhere on the PCB. Once the
component data is registered as a library data, it can be retrieved again for similar components,
thus simplifying inspection data creation. In case the same components are mounted on different
PCB conditions are not identical, the library data of the component may no longer be applicable,
thus might require to append it as new entry into the library.
