17、FET is liable to be damaged by excessive heat and electrical shock. Some proper attention for the soldering operation is required, as follows.1、Recommend to use hand soldering ,thetemperature should be less than 360, and the soldering time should be less than 3 seconds.2、ECM may be easily interfered

18、 by the static electricity , the countermeasure for eliminating the static electricity (grounding for soldering copper, worktable and human body shall be executed.3、Soldering should be accomplished within 2 seconds at each terminal to make sure the ECM is not overheated.4、Airproof of the PCB board i

19、s required,that means a pinhole at the surface of lead lump on PCB wiring board should be avoided necessarily.(A PCB board open to air will influence the sensitivity and performance of ECM.5、Optimal design for heat sink pad is shown as bellow.Shape of the hole at fixed part.AddressBlock 17,Tongfuyu
