RECOMMENDED SCREW MOUNTING ARRANGEMENT Recommended isolated mounting when screw is at heatsink potential. 6-32 hardware is used. 6-32 HEX Head Screw Plain Washer A conical washer should be used to apply proper force to the device. Screw should not be tightened with any type of air-forced torque or equipment that may cause high impact on device package. The interface should apply a layer of thermal grease or a highly conductive thermal pad for better heat dissipation. © Won-Top Electronics Co., Ltd.
