- A sensor development lab requires dedicated space with three areas: main lab for experiments, mechanical workshop separate to avoid contamination, and PCB/PCBA area possibly in the main lab.
- Infrastructure like electrical power, gas/vacuum lines, network, and UPS is foundational and must be set up before equipment to avoid persistent productivity losses.
- Essential bench equipment includes power supplies (Aim-TTI recommended), digital multimeters, oscilloscopes, and ESD protection, with phased procurement based on project needs.
- Signal conditioning instruments are critical for sensor work, including lock-in amplifiers, SMUs, low-noise preamplifiers, and impedance analyzers for precise measurements.
- Environmental control is key for reliable sensor characterization, requiring an environmental chamber, vibration isolation, Faraday cages, and calibrated references for traceability.
- Additional specialized equipment may be needed for RF, optical, chemical, or acoustic sensing, with recommendations for instruments like VNAs, thermal cameras, and fume hoods.
- Mechanical workshop tools include crimping tools, 3D printers, laser cutters, and hand tools, emphasizing separation from the lab to prevent contamination.
- PCB area needs soldering stations (Weller recommended), microscopes, milling machines, and ESD protection, with a stocked component library for efficiency.
- Safety measures include CO2 fire extinguishers, safety cabinets, first aid, and specific protocols for radioactive sources if applicable.
- References like 'The Art of Electronics', Keithley handbooks, and EEVblog provide essential knowledge for lab operations and troubleshooting.
