Production Test Interface Solutions for mmWave and Antenna in Package (AiP)

Incredibly, the number of transistors in integrated circuits (ICs) has tracked Moore’s law, doubling every two years. Equally amazing is the recent jump in IC device operating frequency into the mmWave spectrum. The emergence of 5G, next-generation WiFi protocols, and automotive radar have pushed ICs into these extreme frequency bands to take advantage of the […]

Breakthrough Scalability for Automotive Device Test

New Diamondx VI1x Instrument Enables High Multi-site Automotive and Industrial Device Testing Automotive power electronics IC’s are complex and have stringent test requirements. Typically this limits how many IC’s can be tested in parallel, and thus inhibits the cost-effectiveness of modern highly parallel manufacturing test strategies. The Diamondx platform, with a range of power and […]
