Customer Requirements:
- The customer required a semiautomatic 200 mm probe system that would be used to probe a variety of rf (HF) devices up to 40 GHz. Wafer material could be either silicon or III-V compound. The system had to provide temperature capabilities that ranged from -60 C to 200 C. The devices would get contacted with rf probe cards, multi-contact wedges, rf probes and DC needles. Eight (8) manual manipulators were required – 4 HF and 4 DC with appropriate rf probe arms, rf probe tips and cables.
