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.

New 3D topographical & imaging AOI from Mek

ISO-Spector 3D AOIMek ISO-Spector is an AOI system of ‘true measurement’ for the full across the board inspection of components and solder joints.

Completely New Inspection Capabilities
Unlike other methods of height measurement, ISO-Spector technology enables inspection of heights up to 30 mm (1.2″), and is completely immune to vibrations from nearby placement machines. It is able to inspect the world’s smallest chip size of 008004 (50% of 01005″) and features a full profile simultaneous 2D and 3D inspection while maintaining high inspection speed using patented sensor technology.

• Massive 12 Mega Pixel resolution
• Front and rear high energy, high-end violet lasers
• Minimal Blind Spots
• On the fly Z axis compensation for PCB Warpage
• Off line programming and debug

New entry level, low cost, desktop AOI

iSpector Entry-Level, Low Cost Desktop AOIThe latest generation iSpector desktop AOI from Mek (Marantz Electronics) is designed as an entry-level system for customers with low volume, high mix production requiring high-quality AOI with a low price tag.

Mek’s new desktop solution offers benchtop PCB inspection with exceptional defect coverage.  Providing a rapid, repeatable inspection process at an affordable cost, it’s a plug-and-play installation with iMentor online training and is exceptionally easy-to-program.

iSpector is able to inspect component bodies and solder joints by use of RGB LED light sources from three different angles. This allows 3D meniscus profiling to verify solder joints with low false call rates, accurate tolerance adjustment and amongst the highest defect detection rates in its class.

It utilizes the same powerful 22X software as Mek’s highly respected PowerSpector AOI series. There is no compromise on the wide range of inspection algorithms and component libraries. Complete management of part libraries is possible either on a single AOI system or across multiple machines.

It is fully compatible with Mek’s Catch System for classification, repair and SPC.

The Mek iSpector is currently available in M size (350x250mm) and desktop model only.

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.

Meaningful SPI Production Control Through Automatic Normalization

Automated pre-placement solder paste inspection (SPI) has established itself in SMT assembly as an essential tool for optimizing the process and reducing end of line defects.  It’s been commonly accepted for many years that a majority of assembly defects can be traced back to print defects, and by using raw measurement data from printed PCBs for volume, area, height and offset, SPC histograms and control charts can quite readily be used to optimize the process.

Following optimization, SPI is used to detect print anomalies. However, the multitude of “normal” variables introduced from board characteristics, clamping methodologies, stencil variations and paste type force unacceptably wide tolerance settings.  These board-wide good/bad tolerances can easily mount to +/- 50% or more.  For most, this is unacceptable, because of course, with such wide tolerances production drift can be missed and important defects ignored.

Facing the Challenges of THT Inspection

SpectorBOX - bottom up AOI inspectionThe deployment of AOI technology for THT inspection has historically been restricted by a number of factors. These include the physical configuration of most wave and selective soldering lines, which do not lend themselves to conventionally designed AOI machines that are now popular in SMT flow lines. Product is processed in pallets moving on a continuous drive with automatic return on which the inspection must take place.
