Stencil laser

Click here to enlarge image

A high-performance stencil laser with a high-resolution scanner, the MicroCutII from LPKF Laser & Electronics (Wilsonville, OR) is capable of cutting any shape, including square apertures with rounded corners, at up to 50,000 apertures per hour. This translates to a cutting speed of 11 openings per second. The system also boasts an aperture resolution of 12.5 nm. The laser can cut apertures as small as 30 µm, and its effective material focus diameter of 20 µm produces sharp contours. The stencil laser features the company's PulseShape technology, which reportedly eliminates the heat affect that causes coining or warpage of high-density and thin stencils. As a result, no external coolant is required. The system also incorporates new technology that avoids burrs at exiting edges, so no post treatment is necessary. Circle 53 at www.onlinecenter.to/ils

Microscopy camera

A real-time, full-color, all-in-focus digital microscopy camera, the FocusScope FV-100C from Photron USA Inc. (San Diego, CA) combines high-speed image processing with piezoelectric technology. The light-sensitive CMOS imager operates at 1000 fps. The objective lens on the microscope moves up and down at 15 Hz, while the imager captures 1000 frames. Each picture is scanned in real time by the dedicated image analysis hardware to identify the sharply focused pixels contained in each frame. The selected in-focus pixels are overlaid and reconstructed to form 30 all-in-focus images per second. Circle 56 at www.onlinecenter.to/ils

Laser with storage tower link

The Axel-LT system from Strippit/LVD (Akron, NY) comprises a high-performance CO2 laser machine with integrated material loading and unloading linked to a warehouse featuring one or more material storage units. Material enters the warehouse through a de-palletizing station that facilitates the removal of steel banding and other shipping materials. After the material type, thickness and size are entered into the tower administrator, the material is automatically conveyed to an elevator, which places the material into the tower. Each tower unit has storage capacity of 12 to 14 pallets capable of holding 6000 pounds of sheet material 1.5 x 3 meters in size. The system features the company's WinExecuter software, which manages both the laser and warehouse. Circle 57 at www.onlinecenter.to/ils
