ASSEMBLY PROCEDURE

Although the EPC9104 demonstration unit comes mostly pre-
assembled, the stando s need to be attached to the system
prior to testing. The stando s raise the boards 2 inches above
the work surface to ensure that metal work surfaces do not
interfere with the magnetic elds of the coils. Figure 2 shows
the location and allocation of the stando s for the system. It
is recommended to tighten the nuts by hand to prevent over
tightening them.
If the Voltage feedback cable needs to be attached, use cau-
tion when installing as the Source Coil PCB is thin and can eas-
ily break.
When attaching the heat-sink, observe that it lies at (paral-
lel) with respect to the PCB to ensure proper contact to both
FETs and the gate driver IC. Do not over tighten the screws as
this can damage the screws, thermal interface material, and/
or the FETs.
