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 |
2 -Soldering should be accomplished within 2 seconds at each terminal so as not to be overheated. |
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. |
4 -The pin hole soldering shall be avoided. |
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. |
