10.REGARDING THE SOLDERING OPERATION 焊接注意事項 |
1 -Recommend to use 15W ~ 35W ceramic soldering iron and apply 330±20℃temperature range 推薦使用功率在15W-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. |
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. |
