## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues:
- Pitfall : Inadequate heat dissipation in high-temperature environments
- Solution : Implement thermal vias and heatsinking per MIL-STD-883
- Recommendation : Maintain junction temperature below 150°C
Power Supply Decoupling:
- Pitfall : Insufficient decoupling causing oscillation
- Solution : Use 0.1μF ceramic + 10μF tantalum capacitors at each power pin
- Placement : Keep decoupling within 5mm of component
Signal Integrity Problems:
- Pitfall : Noise coupling in mixed-signal systems
- Solution : Implement proper ground separation and shielding
- Testing : Verify performance with worst-case signal conditions
### Compatibility Issues
Digital Interface Compatibility:
- Issue : 3.3V logic level mismatch with modern processors
- Solution : Use level translators or resistive dividers
- Alternative : Select compatible buffer ICs (e.g., SN74LVC series)
Power Supply Requirements:
- Concern : ±15V supplies not commonly available in modern systems
- Resolution : Implement DC-DC converters with adequate filtering
- Specification : Ensure power supply ripple < 10mV p-p
Aging Effects:
- Consideration : Parameter drift over 15-year service life
- Mitigation : Design with 20% performance margin
- Monitoring : Implement built-in test capabilities
### PCB Layout Recommendations
General Layout Guidelines:
- Use 4-layer minimum stackup with dedicated ground plane
- Maintain 50mm minimum clearance from digital components
- Implement guard rings around sensitive analog inputs
Power Distribution:
- Route power traces with minimum 20mil width
- Use star-point grounding for analog and digital sections
- Separate analog and digital ground planes with single connection point
Thermal Management:
- Provide 1.5cm² copper pour for heat dissipation
- Use thermal vias (0.3mm diameter) under package
- Consider
