Mek’s new GTAz AOI Range Provides the Perfect Combination of 3D and 2D Inspection

Mek GTAz range of selective 3D AOI systemsMek (Marantz Electronics), has announced the launch of GTAz, its newest and most advanced optical head available on the company’s PowerSpector and SpectorBOX range of AOI machines.

The GTAz delivers true Stereoscopic imaging using its 9 high speed (90 Fps) cameras operating in full 24 bit color. This new generation optical head removes the need for expensive capture cards utilising Thunderbolt2 20GBs transfer speeds and full frame transfer. 3D from 9 camera views gives the ability to actually see the side of components rather than extruded 2D images from single camera systems. The result is a perfect combination of the 3D features such as verification of body height, tilt and coplanarity along with the 2D fast programming advantages and pin height and solder meniscus profile analysis, component presence/absence, polarity, value, angle, offset, color, extra part detection, solder ball detection and short detection.

Unique stereoscopic 3D imaging is achieved utilizing the full 9 cameras of the GTAz. The image differentials are merged and a vectorised map of the component is created, then analysed based on the programmer’s applied tolerances. This unique Selective 3D methodology requires no active light projection, and thus is both less costly than other 3D solutions and compact enough to be deployed in desk top systems.

Line Sourced DOAL (Direct On Axis Lighting) coaxial lighting system with high resolution Telecentric Optics enables the inspection of solder joints without shadow effects from tall components nearby as well as accurate inspection model building. Omnidirectional multi angle, multi colour LED lighting provides optimal illumination regardless of component direction.

The modular bottom up/top down SpectorBOX GTAz is optimized for the inspection of THT solder joints and the detection of solder bridges and solder balls.

Top-Down? Bottom-Up? Mek SpectorBOX AOI covers it all!

Recent new additions to our ground breaking SpectorBOX AOI system include a massive 5 inch camera clearance that enables complete single pass inspection of virtually any assembly.

Mek SpectorBOX Bottom-Up / Top-Down AOI systemThe Mek SpectorBOX modular AOI systems have long been optimized for the inspection of THT components to identify defects such as presence/absence, wrong polarity, color, type, and bent pins.  And now, the unique top clearance of 130mm (5.12”) allows the Top-Down SpectorBOX to inspect virtually any completed electronic and  – even when the tallest of components are present.

The SpectorBOX modules can be equipped with 8 wide field of view side cameras in addition to top view camera on the FWAz optical unit.  Its large pixel (18,8μ2) capturing sensor delivers smooth and detailed images with great dynamic range.

Its Z-Axis adjustable optical head can adapt to any PCB thickness, and automatically compensates for warpage. The highly reliable text and polarity inspection on tall components enables the inspection of complex, completed assemblies without the need for fixtures or multiple inspections.

The addition of 8 simultaneously operating multiplexed angular side cameras which are  available for the FWAz model, facilitate active automatic inspection, classification and repair, as the system displays and also stores 9  brilliantly clear defect review angles in full color.

This new configuration effectively complements Mek’s THT Bottom-Up Modular AOI – a system that can be conveniently positioned at any conveyor location. Typically, bottom side PCB inspection requires flipping units combined with a standalone inline AOI. The slim design of the Bottom-Up SpectorBOX instead allows it to be positioned below existing return and/or feed conveyors, saving space and money.

A cost effective way to combine Bottom-Up and/or Top-Down inspections is provided by the Nutek Main Frame, a turnkey solution that enables simple integration of one or two SpectorBOX systems into a production line.  Built for flexibility, it can be configured to the output of any wave or selective soldering system. The ergonomic design is optimized for operators to have eye-height monitors as well as wrist height keyboard and mouse control. This makes operation easy in a standing or seated position, even when dual SpectorBOXes are in use via double monitor configuration. A manual mode allows for smooth offline programming preparation.
