| The various above-mentioned data is measured value, and is not guaranteed performance. |
Breakdown voltage |
| The below shows the test result of AC-7210N which AD-7210N is coated as insulation layer on Aluminum plate's surface. |
 |
AD-7210N could withstand 5000V on average even if it is very thin of 0.12mm. |
Hot breakdown voltage |
| The below shows test results of AC-7210N about breakdown voltage at 20℃(RT),100℃,150℃ and 200℃. |
 |
| AD-7210N can withstand voltage of 5000V even under hot temperature as shown the above. |
Peel strength after long term heat treatment |
| The below shows test results of AC-7210N about peel strength of copper circuit after heat treatment of 175℃ and 200℃ for 3000 hours. |
 |
| Peel strength hardly decreased even after 3000-hour of heat treatment at 175℃ or 200℃ |
RISHO's proposal |
| We propose that substrate for mounting power LEDs could be made with AD-7210N without using ceramic substrate. |
