Micromachining Subsystem

SCANLAB GmbH (Puchheim, Germany) has introduced a new member of its precSYS product line. Five-axis precSYS subsystems enable industrial ultra-short-pulse (USP) laser micromachining of flexible, definable geometries with high aspect ratios. The availability of a subsystem optimized for 515-nm green lasers is particularly attractive in the electronics industry, where it allows creating probe cards with even finer lateral structures. That's exactly half the applied wavelength of a 1030-nm infrared laser, which leads to a much smaller spot size and enhanced lateral precision in processing challenging materials.

All precSYS scan solutions are galvo-based 5-axis subsystems for integration into laser machines. Thanks to their flexible laser beam positioning capabilities (in the x, y, z, α and β directions), these scan heads offer the highest freedom in developing new process strategies. Circular, elliptical or linear trajectories can be defined for processing in 2D or 3D.

Automatic Vision System

The L.S. Starrett Company (Athol, MA) has introduced its AV450 Automatic Vision System. Featuring a larger X,Y,Z measuring envelope of 18” × 14” × 8” (457 mm × 356 mm × 203 mm), the Starrett AV450 has high-resolution video zoom optics and it can be pre-programmed (CNC) for repetitive part inspection, or driven manually via a trackball for individual measurements. Throughput is enhanced by either QC5000 or MetLogix™ M3 software that controls video edge detection and multiple-channel fiber optic or LED illumination. Computer-controlled Quadrant (LED) ring lighting, sub-stage lighting, and optional through-the-lens lighting meet challenging illumination requirements.

Accuracy of the Starrett AV450 Automatic Vision System is 2.5 + 5L/1000 and reading resolution is 4 μin (0.1μm). Magnification on a 24” monitor, 1:1 pixel setting is 37× to 240 × 6.5:1 zoom and 25× to 300 × with a 12:1 zoom. The system has a 1.3 mega-pixel color digital video camera and a precision granite base.

3D Cameras

The second generation of Basler (Ahrensburg, Germany) 3D cameras is ready to launch. Thanks to the latest Sony DepthSense™ ToF technology, the Basler blaze with GigE interface and VGA resolution is particularly suitable for measuring the position, location and volume of objects and for detecting obstacles. Equipped with the latest laser diode technology (VCSEL), the camera operates in the near-infrared spectrum, i.e. in the wavelength range around 940 nm, and is therefore also suitable for use under daylight conditions without compromise. With a multipart image consisting of a distance, intensity and confidence map and a frame rate of 30 frames per second (fps), it generates 3D point clouds and 2D gray images in real time within the camera, reducing the processor load of the host system.

The integrated Sony DepthSense™ IMX556PLR-C sensor with CAPD (Current Assisted Photonic Demodulator) pixel structure, together with the back-illuminated CMOS sensor architecture, enables a much more precise and sensitive scanning of reflected light. This enables the Basler blaze 3D camera, independent of light and contrast and with a resolution of 640 pixels × 480 pixels, to measure optical values almost to the millimeter over a large measuring range of up to ten meters.
