10.REGARDING THE SOLDERING OPERATION  焊接注意事项
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.
每个ECM都包含有个FET.FET在过热和电流冲击下容易损坏。应遵循以下焊接操作规程：

1 -Recommend to use 15W ～ 17W ceramic soldering iron and apply 330±20℃temperature range
推荐使用功率在15W-35W，温度变化范围在330±20℃的陶瓷电烙铁。

2 -Soldering should be accomplished within 2 seconds at each terminal so as not to be overheated.
为防止过热，焊接应在2秒内完成。

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.
应把驻极体传声器固定在散热良好的金属装置（散热板）上进行焊接.

4 -The pin hole soldering shall be avoided.
焊接后，各焊点不应出现砂眼（焊锡小孔）现象.

5 -E.C.M may easily destroyed by the static electricity,and the countermeasure for eliminating the static electricity(the ground for soldering copper,for worktable and for human body)shall be executed.
驻极体传声器容易受静电破坏，应采取防静电措施（焊接器具，工作台，操作人员人体应接地）
