Benchtop AOI system finds fault with larger PCBs

Benchtop automatic optical inspection system is billed as a breakthrough in its ability to handle large board sizes up to 650 x 550mm.

Ideal for large PCBs such as back panels, the M22XDL-650 from Marantz Business Electronics supports comprehensive board inspection, including SMT components, reflow and wave solder joints, and solder paste.

In addition, as larger boards typically feature multiple THT connectors, the new machine incorporates unique Marantz technologies specifically designed to optimise THT solder joint inspection.

With an inspection capability of 100,000 components per hour, the M22XDL-650 is powered by an Intel Pro Mac control system which equips it to deliver best-in-class true 24bit colour imaging.

In addition, Marantz' 22XDL generation introduces an innovative lighting concept incorporating three pulse wave modulated LED light sources and up to six different lighting combinations.

When combined with ease of programming and a substantial usability advantage, the system significantly enhances operator control for highly reliable board inspection.

"I believe that the M22XDL-650 is the best AOI machine on the market for extremely large board sizes, delivering exceptional inspection accuracy for customers around the world", explains Marantz Business Electronics General Manager, Henk Biemans.

"We pioneered true 24bit colour imaging to give us more data per pixel and dramatically extend defect detection while minimising false alarms".

"24bit processing discerns subtle changes for improved image clarity, helping to separate components and solder images from the background board or substrate".

"All Marantz AOI systems deploy this technology in combination with our innovative angled and coloured lighting solutions to overcome the limitations of 8bit greyscale imaging".

"Significantly enhancing inspection accuracy and reliability for manufacturers handling larger boards, the M22XDL-650 is an ideal solution for environments prioritising flexibility and control".

Featuring a bottom side clearance of 100mm and a top side clearance of 40mm, the M22XDL-650's versatility effectively meets the challenges of odd-form components.

And, as the system's high-speed digital video CCD camera moves in x and y planes, the stationary PCB can be fixtured for optimal support, avoiding warping and further enhancing inspection results.
