NOTES:
1. The High Conductance board is based on modeling done to EIA/JEDEC Standard JESD51-7. The board emulated contains two one ounce
thick copper ground planes, and top surface copper conductor traces of two ounce (0.071 mm thickness of copper).
2. The Low Conductance board is based on modeling done to EIA/JEDEC Standard EIA/JESD51-3. The board does not contain any ground
planes, and the top surface copper conductor traces of two ounce (0.071 mm thickness of copper).
3. The Very Low Conductance board is based on the EIA/JESD51-3, however the thickness of the surface conductors has been reduced to
0.035 mm (also referred to as 1.0 Ounce copper).
4. The above mentioned JEDEC specifications are available from:
