Technical details and manufacturing context for Signal Processing Board

Definition
A specialized electronic component within the Fish Bone Detection Sensor Module that receives raw electrical signals from detection sensors, amplifies, filters, and converts them into digital data for analysis and decision-making regarding fish bone presence in food products.
Working Principle
Receives analog signals from fish bone detection sensors, applies signal conditioning (amplification, filtering, noise reduction), converts signals to digital format via analog-to-digital converters, processes data using embedded algorithms to identify bone characteristics, and outputs processed data to the module's control system.
Common Materials
FR-4 PCB substrate, Copper traces, SMD electronic components, Silicone conformal coating
Technical Parameters
  • Board dimensions typically range from 50x50mm to 100x100mm depending on complexity (mm) Standard Spec
Components / BOM
  • Analog-to-Digital Converter
    Converts analog sensor signals to digital data for processing
    Material: silicon semiconductor
  • Signal Amplifier Circuit
    Boosts weak sensor signals to usable levels
    Material: copper traces and semiconductor components
  • Digital Signal Processor
    Executes algorithms to analyze bone detection patterns
    Material: silicon semiconductor
  • Power Regulation Circuit
    Provides stable voltage to all board components
    Material: copper traces and electronic components
Engineering Reasoning
0.1-5.0 V input signal range, -40°C to +85°C ambient temperature
Input voltage exceeding 5.5 V causes op-amp saturation, temperature exceeding 90°C triggers thermal shutdown
Design Rationale: Semiconductor junction breakdown at 5.5 V due to Zener effect, silicon thermal runaway above 90°C
Risk Mitigation (FMEA)
Trigger Electromagnetic interference from adjacent 480 VAC motor drives
Mode: Signal-to-noise ratio degradation below 20 dB causing false detection
Strategy: Shielded twisted-pair cabling with ferrite cores and differential signaling
Trigger Capacitor electrolyte drying at 85°C ambient temperature
Mode: Power supply ripple exceeding 100 mVpp disrupting ADC conversion
Strategy: Solid polymer capacitors rated for 105°C and 5000-hour lifespan
