Test System Solutions



Flexible, Cost Optimized Test Solutions for the Most Challenging Applications

Diamondx test system extends Cohu’s low-cost, high-throughput production test solution platforms to high pin count, higher site count wireless, mobility, SOC, Flat Panel Display drivers, Power Management, and microcontrollers. Designed to meet the cost driver’s IC companies face, Diamondx extends Cohu’s leadership in lowering the cost of operations.

Breakthrough cost reductions in both capital and operating costs for the automotive, mobility, IoT/IoV/Optoelectronics, industrial and medical, and consumer markets.

Proven capability in high-density digital, DC, analog instruments as well as technology leading precision analog, SerDes, RF and Automotive test makes the Diamondx test system suitable for today’s broad range of devices.

Changes the Rules of Design Through to Production Test

The Diamondx DxV provides full semiconductor ATE performance in a desktop PC footprint. Fully integrated, ultra-compact test system designed to be used in the engineering lab or office. Unlike traditional semiconductor ATE solutions that is no mainframe, separate workstation or support cabinets needed. The DxV is completely stand-alone, so it can be placed on a bench or desktop:

  • Ultra-compact, small footprint, light weight, single box design
  • Air-cooled with low ambient noise for an office environment
  • Energy-efficient, low power consumption
  • Ideal for lab development and high-volume production
