Automated Optical Inspection (AOI) system doesn’t have to be complicated, time consuming or expensive

Many companies, especially smaller electronics manufacturers, put off adding automated optical inspection (AOI) to their process because of the high capital investment, the sharp learning curve, and the need for an experienced operator to program and fine-tune it.

Benchtop Sherlock-300F AOI machine was designed to make in-house AOI affordable and manageable for first-article inspection, prototyping, and even full production inspection requirements. It features the same technology and quality build of the batch and inline Sherlock-300 models—plus the same two full days of installation and training at your facility offered with the other models*—in a smaller size, at a lower price point.

Think your boards are good?

In a test of 10,000 assemblies, machine inspection was found to be 99.99% accurate, compared to only 72.36% with manual inspection. How much is that 28% difference costing your company?

Sherlock-300F desktop AOI system offers a cost-effective way to catch defects, monitor trends, and improve your overall process. The initial equipment investment is quickly paid off in other ways, too, with increased throughput (AOI is much faster than manual vision inspection) and lower operational costs (automated optical inspection is less labor intensive than manual inspection as well). 

Easy to program and operate

Easy to program AOI systemAll programming and operation is done through the Sherlock-300F’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.

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

RGB lighting for solder joint inspectionSherlock-300F 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-300F 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

High-quality componentsDuring 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-300F 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

Statistical Process Control software availableDo 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 available

Repair station software designed to work with the Sherlock-300F 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.

Installation & Training Included

To ensure that your team is up and running with the Sherlock-300F as quickly and smoothly as possible, machine purchase includes 2 days of installation and training onsite at your facility*, provided by a trained and knowledgeable Manncorp technician. Manncorp technicians receive high marks from our customers for their willingness to work with them to solve problems and ensure satisfaction with their purchase.

*2 days of installation and training included in product price; customer pays technician travel and lodging.

Defect Coverage

Sherlock-300’s scanning speed is independent of the number of components on the board: even densely populated boards are scanned at rates of 50 cm2/second. Fast cycle times keep the system from bottlenecking production—a 7.3" x 5.1" (185 mm x 130 mm) PCB with 253 parts can be processed in 10 seconds, including load and unload time.
