                        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 ~ 35W 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)
