Expanded flexibility with Mek’s Modular Top Down AOI

The Mek SpectorBOX modular AOI systems have long been optimised for the inspection of THT components to identify defects such as presence/absence, wrong polarity, colour, 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 electro-mechanical assembly, even when the tallest of components are present.

The SpectorBOX modules can be equipped with eight wide field of view side cameras in addition to top view camera on the FWAz optical unit. Its large pixel 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 eight 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 nine clear defect review angles in full colour.

Jeremy Saise, Technical Director, Mek, explained further: “Everyone’s goal is to minimise human mistakes. Our sensors also provide high quality images that aid operators in the defects classification process, and those same images are stored in a database. Imagine having fingertip access to all products with 8x views of every component.”

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 optimised 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.
