Every ECM contains a FET with microphone boby.This FET is easy to damageable from excessive heat and electrical shock.Proper attention for the soldering work is required same as followings.
每個ECM都包含有個FET.FET在過熱和電流沖擊下容易損壞。應遵循以下焊接操作規程：

1 -Recommend to use 20W ～ 35W ceramic soldering iron and apply 330±20℃temperature range
推薦使用功率在20W-35W，溫度變化范圍在330±20℃的陶瓷電烙鐵。

2 -Soldering should be accomplished within 2 seconds at each terminal so as not to be overheated.
為防止過熱，焊接應在2秒內完成。

3 -ECM shall be soldered fixed on the metal block(heat sink)which has the higher radiation effects. Heat sink shall contact with each of ECM.
應把駐極體傳聲器固定在散熱良好的金屬裝置（散熱板）上進行焊接.

4 -The pin hole soldering shall be avoided.
焊接后，各焊點不應出現砂眼（焊錫小孔）現象.
