I am designing a Power PCB test fixture. It will be built out of a rack style enclosure. I have included a picture of a similar fixture. The top of the enclosure will be made out of G10 and that is what I need designed. I have .stp files for the UUT(Unit under test). The fixture must be designed to allow the UUT to mate to the fixture with and without the heatsink attached. A cover will also need to be designed so that the operator is not subjected to the High Voltage that is required to test the UUT. An NDA will be required to move forward.
