做光控產品的工程師多少遇到過這個場景：同一批電路板，用的是同一型號光敏傳感器，BOM一模一樣，產線測試也通過了——但到了現場，有的燈天剛暗就亮了，有的非要全黑才亮。客戶投訴"靈敏度不一致"，你拆機換了個管子就好了。可問題是，這批管子來料檢測明明是合格的。根因往往不在電路設計，而在于一個容易被忽略的環……

我們工廠的紅外人體感應探頭的腳數不同，功能也有所區別：### 三腳探頭- **VCC**：電源正極- **GND**：電源負極- **OUT**：信號輸出### 四腳探頭- **VCC**：電源正極- **GND**：電源負極- **OUT**：信號輸出- **EN**：使能控制（可選）### 六腳探頭- **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： 通常封裝完的IC，膠體或Substrate PCB 在一般的環境下 會吸收濕氣，造成IC在過 SMT回流焊時，發生“爆米花”(POPCORN)的狀況。濕氣敏感性等級(Moisture Sensitivity Level，MSL) 被用來定義 IC 在吸濕及……
