5G mmWave: Multi-site RF Probe Cards Enable Lower Cost-of-test in Mass Production
5G mmWave systems are here. Advanced Antenna-in-Package modules and RFFE chipsets are integral to the latest generation of high-end smartphones and tablets, and this capability is becoming more ubiquitous in 2022. These chips, containing a massive amount of mmW content, are ramping in mass production, and the companies producing them need a way to reduce cost of RF test. To realize actual cost reduction, tester and probe card companies need to evolve quickly to support increased parallelism of mmWave testing. This session drills down into the RF test cell to examine enhancements enabling increased parallelism using new probe head architectures.
