State College, PA State of the Art (SOTA) has introduced a compact, lightweight chip resistor line that meet the visual inspection requirements of Mil-PRF-38534 and are ideal for use in hybrid applications requiring the exclusive characteristics. The resistors range in size form 0202 (5.08 x 5.08 mm) to 2512 (6.35 x 3.175 mm), with tolerances from 0.1%, power ratings from 20 mW to 2000 mW, temperature coefficients of resistance as low as 25 ppm, and voltage ratings from 15 V to 200 V. The operating range for these resistors is from -55 °C to + 125 °C. Top side termination finish is gold designed for wire bondable applications. This Alumina product line along with the company’s established silicon product line offers a complete resistor solution for hybrid manufacturers. Reliability is assured by extensive in house testing. Users can select from a wide variety of testing options from high reliability screening to life testing. Custom testing to customer specifications is also available.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
