Sherlock 300I Inline AOI Machine

Sherlock 300I Inline AOI Machine

The Sherlock 300I Inline AOI machine brings fast, reliable automated optical inspection directly to your production line—either pre- or post-reflow. Designed to inspect SMT, through-hole, and mixed-technology assemblies, the 300I quickly identifies component and solder defects and integrates seamlessly with downstream equipment for automatic sorting of good and bad boards. This reduces handling time and enhances overall process efficiency.

With a 100% touch-based user interface, the Sherlock 300I is as intuitive to operate as a tablet, making it accessible for operators of all skill levels. Its compact inline design and robust inspection capabilities make it an ideal solution for manufacturers looking to boost quality control without slowing down production.

Smart, Compact Inline AOI with Intelligent Board Handling and Offline Programming

The Sherlock 300I seamlessly integrates into your existing SMT or through-hole production line, providing comprehensive inspection either before or after reflow, or following wave soldering. Its compact footprint and advanced, algorithm-driven software ensure thorough defect detection—including solder joint quality, component presence, polarity, and placement—without slowing down your line. To maximize productivity, programming can be performed offline at a separate station, eliminating downtime during recipe creation or updates.

After inspection, the Sherlock System communicates directly with downstream equipment to route boards appropriately. Accepted PCBs proceed automatically down the line or into a good board rack, while rejected boards are flagged for rework. Manncorp also offers an optional AOI rejection conveyor, which stops failed boards for operator review or diverts them to a dedicated rework rack—enhancing traceability and quality control without interrupting the production flow.

High-Speed, Low-Vibration Inspection Designed for Pre-Reflow PCBs

All Sherlock Systems feature a high-rigidity X-Y biaxial drive mechanism that enables smooth, high-speed movement of the imaging unit while maintaining exceptional accuracy and stability. Its low-vibration camera drive is specifically engineered for inspecting PCBs before the reflow process—when components are not yet soldered in place and especially sensitive to movement. During inspection, the PCB remains stationary on the conveyor, allowing for clear image capture without disturbing parts that have not been fixed.

To further reduce vibration and enhance inspection reliability, the system incorporates advanced motion control technology originally developed for high-speed semiconductor wafer handling. This technology precisely manages acceleration and deceleration, minimizing mechanical stress and ensuring stable imaging conditions even during rapid inspection cycles. The result is a reliable, non-intrusive AOI solution for delicate, pre-reflow assemblies.

Enhanced Dual-Lighting for Accurate Solder and Component Evaluation

The Sherlock System incorporates a sophisticated RGB lighting setup designed to improve both the clarity and speed of solder joint inspections. This lighting method distinguishes flat solder pads in red while highlighting sloped fillet regions in green or blue, delivering a single image that clearly separates horizontal from angled surfaces. When solder joints are properly formed, they display three distinct color zones—making it straightforward to evaluate coverage, shape, and overall integrity. When paired with high-speed imaging, this technique ensures fast and accurate inspections ideal for high-throughput production lines.

Beyond RGB illumination, Sherlock Systems also include high-intensity white LEDs that ensure precise analysis of component features such as color codes, text markings, orientation, and alignment. This facilitates reliable identification of resistor bands, connector labels, OCR text, and polarity indicators. The uniform lighting and shadow suppression contribute to low false-call rates and consistent inspection accuracy across a diverse range of components.

Simplified Programming, Powerful Performance

The Sherlock System makes AOI programming and operation easier than ever with its user-friendly, touch-screen interface. Built-in automation features—such as automatic pick-and-place data conversion and CAD import—streamline setup, while a robust, customizable parts library eliminates the need for highly skilled AOI operators. These tools dramatically reduce programming time and simplify inspection setup for even complex boards.

Unlike the limited libraries found in many AOI systems, the Sherlock parts database contains extensive inspection parameters for each component. These include optimized image processing settings, specific lighting conditions, defined inspection zones, and more. Users can quickly modify existing parts or create custom ones, ensuring the system adapts easily to unique production requirements.

Designed with usability in mind, the software provides an intuitive experience for both novice and experienced operators. A helpful “Navigation Mode” guides users step-by-step through programming and inspection processes, and built-in online help is available at any time for immediate support. The full user manual is integrated into the software, with an easy-to-use function lookup tool. All advanced functions and their attributes are clearly explained, enabling users to fully leverage the system's capabilities without extensive training.

More Than Inspection — Improve Process Performance

Take your inspection capabilities further with the addition of Statistical Process Control (SPC) software. Running independently from the Sherlock System on a separate PC, SPC helps uncover early signs of process variation, monitor long-term performance, and identify recurring quality issues. By converting inspection data into clear, actionable information, this tool empowers smarter decision-making that leads to higher yields, fewer defects, and better overall process control.

To streamline operations and boost traceability, the Sherlock System’s built-in camera can read both linear and 2D barcodes—removing the need for dedicated scanning hardware. It also includes OCR functionality, enabling accurate reading of part numbers, component labels, and other printed data as part of the automated inspection workflow.

Trace and Repair Made Easy

Sherlock's dedicated optional repair station software streamlines the rework process by giving operators detailed visual and textual information for each rejected PCB. At the repair station, personnel can instantly access high-resolution images of the failed component, along with its part name, location on the board, and reason for rejection. When paired with a barcode scanner, the system allows users to instantly call up board-specific data with a quick scan of the PCB’s label—saving time and reducing the risk of handling errors.

Inspection and repair history is fully searchable by serial number, making it easy to track issues and confirm completed fixes. When connected with Sherlock's SPC (Statistical Process Control) software, the system also compiles and analyzes repair data to identify trends and problem areas—providing end-to-end traceability and enabling continuous improvement across your production process.
