Hands Off

Sherlock-300B is a standalone AOI system that borrows one of the best features of inline systems: the operator doesn’t lay a hand on a single PCB. Load a standard M-size rack of PCBs on one side of the machine and an empty rack on the other, then run the inspection program. The board transport system automatically adjusts to fit the board width, then it begins processing the batch of boards, separating good from bad with a spacer in the output rack. This allows for faster throughput rates and less operator intervention than batch systems that require the operator to load each board.

Easy to program and operate

All programming and operation is done through the Sherlock-300B’s intuitive touch-screen interface. Automatic pick & place and CAD data conversion and a pre-defined, customizable parts library not only speed up programming but also eliminate the need for skilled AOI personnel.

Unlike the libraries included with many other systems, the Sherlock 300 library contains comprehensive inspection data for each part, including image processing settings, lighting conditions, areas to be checked, and more. Custom parts can be quickly created from any pre-defined part.

The software was designed to make operation easy and convenient: The interface is instantly intuitive. If there’s any doubt, “Navigation Mode” can step the operator through tasks, and online help is only a click away.

For optimum speed and traceability, the Sherlock-300’s camera reads 2D and linear bar codes—no separate bar code scanner is required. The system also performs character recognition, allowing it to process and compare component labels.

The software also features easy zooming in and out to get a better look at defects. It also presents quick-stats on defective parts.

The system can optionally be programmed offline, at a separate PC, in order to keep the AOI station free to perform inspections.

High Defect Coverage

Sherlock-300B uses a high-resolution, 2.2-megapixel CMOS camera, a large-aperture telecentric lens, and two lighting systems to achieve fast, accurate inspection of both solder quality and components at a scanning rate of 50 cm²/sec.

The RGB LED lighting system inspects solder fillets for volume and shape. The three-tier white lighting system inspects component placement and positioning, with reflection and shadow controls to ensure low false calls and low false accepts.

The standard lens inspects parts down to 0201, or the Sherlock-300B can be fitted with a high-magnification lens to inspect parts down to 01005. Both of these telecentric lenses eliminate perspective errors, reduce distortion toward the edges of the field of vision, and provide uniform image plane illumination.

There is no need for the expense of high-megapixel cameras or multiple side-angle cameras with this system. It has been designed to provide accurate, reliable inspection results with the lowest complexity of programming and at a cost that’s within reach of small and medium manufacturers.

Quality Components Throughout

During inspection, the camera moves, rather than the PCB. This ensures the clearest possible images and fastest inspection speeds. The camera motion system is X-Y bi-axial belt-driven with 50 µm positional accuracy.

The board transport system automatically adjusts to the size set in the program. Sherlock-300B comes standard with a pneumatic PCB stopper and vacuum clamp. It can optionally be purchased with a motor to eliminate the need for a compressed air source.

Operation is smooth and quiet, thanks to the machine’s sturdy, vibration-damping construction.

All components are high quality, Japanese-made.

Keep Control of Your Process

Do more than detect bad PCBs. Improve your whole process with the addition of statistical process control (SPC) software. This software, installed on a separate computer from the Sherlock-300, allows you to detect process abnormalities early, view trends over time, and discover where your problem areas are.

Trace and Repair

Repair station software designed to work with the Sherlock-300B simplifies rework by providing details at the repair station on each rejected board. Repair station personnel can access an image of the rejected part, with its location, name and details of inspection. With the connection of a bar-code reader, board data can be brought up on screen with a quick scan of the PCB’s label.

History of inspection and repairs can be search by serial number. When linked with the SPC software, repair data can be tallied, providing complete traceability.
