UltraVision Automated Optical Inspection

The future of AOI

UltraVision is the flagship Automated Optical Inspection system from DCB Automation which is pushing the boundaries to new levels of inspection capability not previously seen from bench top Automated Optical Inspection systems; at an affordable price.

• 4M pixel colour CCD camera (Firewire B for fast image transfer) providing 10.6µM resolution suitable for 01005 components
• Telecentric Lens to ensure no distortion of image.
• Laser Co-planarity capability for BGA and IC lead inspection (automatic lead height profile) now providing the highest level of performance from a bench top AOI system; as standard
• State of the art micro-stepping motions for accurate positioning of the X/Y camera gantry
• Faster inspection speeds due to 22mm x 22mm inspection frame
• Standard inspection area 470mm x 450mm
• Tray for board handling with tooling to allow multiple board/panel inspection
• 3 tier coloured LED lighting for accurate solder inspection
• Intuitive and easy to use DCB in-house developed software for rapid program generation using model libraries and new rule based algorithms
• Clear and concise screen details for fault analysis
• 22" widescreen TFT monitor and high specification dual core processor PC
• Off-line software included for programming and rework facility
• UK designed and manufactured

With an Industrial grade camera system using a telecentric lens picture quality from the UltraVision Automated Optical Inspection system is exceptional, and the 22mm x 22mm inspection frame size allows for fast scanning of all boards at full resolution. This system achieves excellent throughput rates, with exceptional fault detection whilst flagging a minimum of false calls.

With the unique, in-house developed, software UltraVision is easy to programme and user training and support ensures every user gets the best out of the system every time. Time to develop new programmes has been reduced with the model library system, with simple on screen guidance for new parts. Rule based algorithms allow for multiple inspection methods and tight control over pass and fail to help eliminate false-calls.

Clear on-screen graphics illustrate the faults and also their location on the board, making re-work easier and quicker. Clear and simple security levels protect programme data from unauthorised modifications, whilst making it easy to modify the inspection programme for changes and alternatives.

Programming and re-work can be carried out off-line (a second software licence is included with the unit) to ensure maximum productivity.

For rapid board verification the unit can be operated in Comparator mode, comparing against a “Golden Board”, but with the speed of programming for a fully automated optical Inspection this is rarely used.

UltraVision can also be ordered with magazine feed capability for any organisation using this board handling technique. For more details on this option click here.

Laser IC & BGA co-planarity inspection capability

Automatic Optical Inspection has become a "must have" for any PCB process. However, no matter what lighting or how many cameras are used, the need to provide consistent co-planarity inspection of IC legs, BGA’s or other important parts remains.

We are providing an ideal solution to this by directly measuring the height of each IC leg using a Scanning Laser Triangulation system. Lifted Legs is one of the hardest problems to pick up and this solution provides excellent results with both photographic and numerical data to help an operator decide how to resolve the issue. This capability within our  Automated Optical Inspection system requires no additional programming as the system will "automatically" determine where to undertake the Laser Height profile from the optical inspection results. BGA devices can be inspected for absolute seated height and co-planarity. This unique way of inspecting IC pins makes  the solution to this difficult issue and investment in our Automated Optical Inspection system is now "future proof" at an acceptable cost.

Polarity Checking

Using the innovative lighting system on the Ultravision Automated Optical Inspection system it is easy to highlight even the smallest of polarity marks, ensuring all components are correctly polarised. With intelligent pattern recognition rotation can be double checked against the full pattern for that part.

Position Checking

Using a simple masking and pattern match technique components placed at any angle on the board can be checked for correct position and rotation.

Marking and labeling checks

Using a combination of OCV and OCR as well as colour (Hue, Saturation and luminance) the system can check for marking and colour coding of any components, making use of rule based algorithms to allow for alternates and colour variations.

Solder Inspection

Using the angled colour lighting capability our unique analysis software allows the system to build a profile of the solder on the joint and using multiple selections of parameters can easily cope with differences in different joints, and consistency on adjacent joints.
