10.REGARDING THE SOLDERING OPERATION 焊接注意事项 |
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. |
