Semiconductor test platform Hatina 4S

Overview
The Hatina 4S by Cosmic is a compact, modular ATE platform designed for wafer-sort (WS) and final test of MEMS devices and magnetic sensors. The system supports stimulus modules for humidity, pressure and temperature sensors, microphones, magnetometers and twist-tilt units for accelerometers and gyroscopes. Its scalable architecture enables high parallelism up to 140 sites in ping-pong mode and a minimal footprint for easy integration into handlers and automation lines.

Key benefits

• Compact modular solution for production testing of MEMS and magnetic sensors
• High-pin-count V/I channels and dynamic power supplies (DPS)
• High-density digital channels and PPMU options
• Integrated multiplexing for channel reuse and flexibility
• Low cost-per-site via high parallelism
• Simplified integration with automation and handlers

Available variants

• Hatina 4S Magnetic — stimulus system with Magneto Board and high magnetic field generation (patented coil-less design)
• Hatina 4S MEMS — configuration optimized for MEMS devices (accelerometers, gyroscopes, pressure, temperature, humidity, gas sensors)
• Hatina 4S Microphone — New Era microphone system with audio modules and AWG per site for MEMS microphone testing

Product presentation summary
The Hatina 4S targets high-parallel production testing of MEMS and magnetic sensors. Notable technical highlights include a patented coil-less magnetic field generator (up to 400 Gauss) with 3D rotation, microphone test capability with up to 75 dB SNR and 140 dB SPL, a noise floor below 20 dB and amplitude accuracy better than 0.1 dB, support for climatic chambers from −40 °C to +180 °C, and accelerometer/gyroscope modules enabling multi-site parallel testing. The platform focuses on compact footprint, configurability and minimizing unit test cost through high site counts.
