Marantz recently launched its PowerSpector, a powerful new AOI system, at the SMT Nuremberg exhibition.
The PowerSpector system improves on the performance of Marantz's DL Series of AOI systems. With an Apple Mac controller at its heart, PowerSpector adds a new generation of fully re-engineered optics, which includes a custom image sensor plus proprietary lenses and lighting technology, to provide detailed analyses of high resolution image data captured and processed in full 24-bit colour.
This system offers a DOAL line light source for improved image contrast and signal dynamics, a multi-angle lighting system with meniscus profiler and a 70% larger field of view (FoV) than the DL series. In all, this is said to deliver a 25% increase in speed.
The meniscus profiler works with the system's new multi-angle lighting to analyse detailed 24-bit colour data for powerful solder joint integrity validation. In comparison to systems using monochrome analysis, 24-bit colour imaging delivers superior performance in the identification of defects on gold or copper plated boards.
On PowerSpector, Marantz' Synthetic Imaging algorithms - which deliver a balance between defect detection and false rejects - have been augmented with new Spectral Analysis algorithms to further improve the blend of programming speed, powerful defect detection and low levels of false rejects.
PowerSpector's intrinsic flexibility means it can be deployed in line at any stage of the assembly process: either after the printer to check solder paste deposition; after the placement machine to verify component characteristics and pin-in-paste; or post-reflow or wave soldering to validate component and solder joint integrity. Programming is also flexible, taking just minutes to ready a functioning program in Prototype Mode to verify assembly line setup before production.

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
