XY-Theta Alignment Stage

An alignment stage from Optimal Engineering Systems, Van Nuys, CA, is a high-resolution, high-repeatability XY-theta stage for such applications as angular glass cutting and grinding and laser cutting and drilling. The linear resolution of the X and Y axis is 5μ (non-micro-step) or 0.125μ (20 micro-steps per step motor driver in use). The repeatability is 1.5μ, and positional accuracy is 5μ. The 1-mm per-turn lead screws and preloaded V-groove and crossed roller bearings add to the high precision and stiffness of the XYR-03-01 alignment stage. The linear travel of the X and Y axes is 50 × 50 mm.

Automated Dispensing System

Nordson ASYMTEK, Carlsbad, CA, has released a new automated dispensing system for medium and bulk volume deposits of single- (1K) and two-component (2K) materials in electronics manufacturing and printed circuit board assembly. The Helios™ SD-960 Series is ideal to deposit volumes greater than 1 cc, and line widths and dots that exceed 1 mm, but it can deposit volumes down to 0.3 cc and line widths as narrow as 0.3 mm. The system supports highly abrasive thermal interface materials, silicones, epoxies, and grease for applications such as potting, sealing, gasketing, and structural adhesives. The system was made specifically to accommodate large parts and substrates. The frame is 200 mm taller and the robotics 150 mm higher for more overhead clearance than a standard dispensing platform.

Custom ESD Foam Packaging

BEST Inc., Rolling Meadows, IL, has released a custom ESD insert cutting program. The inserts are designed to protect high-valued PCBs or electronic components from shipping damage during the design phase prior to the board and packaging design being finalized. The company can take in material and design the package cutout from mechanical drawings or samples. Custom cutouts can be shipped within two working days after acceptance of the drawing.
