做光控产品的工程师多少遇到过这个场景：同一批电路板，用的是同一型号光敏传感器，BOM一模一样，产线测试也通过了——但到了现场，有的灯天刚暗就亮了，有的非要全黑才亮。客户投诉"灵敏度不一致"，你拆机换了个管子就好了。可问题是，这批管子来料检测明明是合格的。根因往往不在电路设计，而在于一个容易被忽略的环……

我们工厂的红外人体感应探头的脚数不同，功能也有所区别：### 三脚探头- **VCC**：电源正极- **GND**：电源负极- **OUT**：信号输出### 四脚探头- **VCC**：电源正极- **GND**：电源负极- **OUT**：信号输出- **EN**：使能控制（可选）### 六脚探头- **VCC*……

Q: No high level appeared when pir was testing the timing. Did pir crash? Answer: pir is not dead, it should be PIR data ready to produce high power, is forced to pull down by the MCU. You can directly supply power to the pir, use the oscilloscope to see

1. The connection between the PIR and other devices should be as short as possible. On the dual panel or multi-layer board, try not to route the cable below the connection, especially if there is no large current. 2. PIR part of the circuit as far as poss

MSL： 通常封装完的IC，胶体或Substrate PCB 在一般的环境下 会吸收湿气，造成IC在过 SMT回流焊时，发生“爆米花”(POPCORN)的状况。湿气敏感性等级(Moisture Sensitivity Level，MSL) 被用来定义 IC 在吸湿及……
