KEM Application Note No.TCL-97009Thermal conductivity measurement Kyoto Electronics Manufacturing Co.，Ltd.Data No.HB11-97126 Thermal conductivity of ceramic -Summary- Checked the possibility of measuring thermal conductivity(TC) of ceramic (thickness： 20mm) byQTM-500.Consequently， good reproducibility was obtained with RSD approximately 1.5%. TC of frontand rear did not show any difference. -Measuring instrument- Main unit： QTM-500 Quick thermal meter Probe： PD-13 Insulating probe (1)Activated QTM-500 and left it over onehour. (2)Set the heater's current volume at|=6.(3)Placed the prove on sample andmeasured TC of both sides， front andrear. Front Rear First： 4.907(W/m·K) 4.863(W/m·K) Second： 4.849 4.792 Third： 4.852 4.731 Fourth： 4.726 4.862 Fifth： 4.792 4.926 Mean： 4.825 4.835 SD： 0.069 0.075 RSD： 1.4(%) 1.6 (%) -Ambient condition- Ambient： 24.9℃ Humidity：47 % Weather： Fine -Comment- When probe is put on the sample， care should be taken for making close contact between sampleand probe. 京都电子工业株式会社-可睦电子(上海)商贸有限公司l _上海市中山西路2366弄1号203室 电话：021-54488867 电邮：kemu-kem@163.com 网址： http：//www.kem-china.com
