    Remark: (1) All test data provided are typical values and not intended to be specification values. (2) Hi-Pot proof test (600VDC) is performed 100% on the whole working panels (with copper foil). Any higher requirement of Hi-Pot test can be AABUS. (3) Breakdown test is a destructive test, which is done on substrate (without copper foil) of a random sample in the FQC laboratory. Disclaimer: The information and data contained in this technical literature is based on data and knowledge correct at the time of publishing/printing and is believed to be accurate and is offered in good faith for the benefit of the user. The user should make his own tests to verify the suitability of this product for any application before its use. All data are typical values only and subject to change without notice.
