关键器件四步选型
main controller and measurement processor
- Need: Dual-core processing, Wi-Fi/BT for telemetry, multiple ADC channels for oscilloscope/temperature sensing, and high-frequency PWM outputs for heater control.
- Class: Wi-Fi + BLE SoC with integrated ADCs and hardware timers
- Shortlist: ESP32-WROOM-32, ESP32-S3-WROOM-1
- Pick: Select based on required GPIO count, dual-core processing capability for real-time PID + GUI/oscilloscope rendering, and flash memory size.
USB-C PD power negotiation and multi-rail DC-DC conversion
- Need: Negotiate up to 20V/5A (100W) via USB-C PD and step down to power the MCU, analog front-end, and high-power soldering iron heating element.
- Class: USB Type-C PD Controller + Synchronous Buck-Boost Converter
- Shortlist: FUSB302 + TPS63802, CH224K + MP28167
- Pick: Select based on maximum input voltage tolerance, peak current rating for soldering burst power, and thermal footprint constraints.
风险清单
| ID | 领域 | 等级 | 说明 | 缓解 |
|---|---|---|---|---|
| r1 | thermal | high | High thermal dissipation inside a compact portable enclosure from both the power regulation stage and the soldering handle interface. | Implement strategic copper pours, thermal vias, and software-based over-temperature foldback protection. |
| r2 | emi | high | High-frequency PWM switching noise from the soldering iron heater and DC-DC power supply can severely couple into the integrated oscilloscope measurement channels. | Use separate analog and digital ground planes, differential routing for sensitive ADC inputs, and adequate filtering capacitors on the measurement front-end. |
| r3 | power | med | Incompatible or low-power USB-C power adapters may cause system brownouts when both the soldering iron and adjustable power output draw peak currents simultaneously. | Implement robust USB-C PD negotiation logic with dynamic power budgeting and automatic load shedding in firmware. |
上电与验证计划
- 断电检查、极性确认与电源轨对地阻值检查
- 限流首次上电，在启用负载前逐路确认电压与纹波
- 按子系统逐项验证接口、电平与时序
- 结合目标环境执行热测试、故障注入、EMC预扫与耐久测试
