Hello folks. Is there anybody to know that what application support the Buried Reisistor? I want to debug the board which has resistive layer in inner layer. The stackup is below: ------------------- COMP ------------------- FR4 -------------------SIGNAL_2 -------------------Resistive Layer -------------------FR4 -------------------GND -------------------FR4 -------------------3.3V -------------------FR4 | | ... How can I view the signal integrity in according to Resistive Layer? Many tool is not supported the buried resister, is it right? When I define the crosssection in tool, I have a big problem. Signal_2 is conductor layer, and Resistive layer is conductor layer too. But not defined. They need a dielectric between Signal_2 and Resistive layer but not existed in real world. How can I set the crosssection in tool like that? Thank you for your reading. Any comment is good for me. Inmyung. ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
