Optical head delivers true stereoscopic imaging
Mek has announced the launch of its GTAz, an 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 colour.
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.
