Mechanical Instructions

Designed to directly mount to Cree 45 mm style power modules, the 6-ch gate driver also has several

other mounting holes to secure the assembly.

Attach the gate driver board to the power module via the 4x Module screw holes (see diagram below)

using the recommended hardware in Table 1. Then solder the 28x solder pins via the solder pin holes to

electrically connect the driver board to the power module. The solder must not exceed 260ºC and the

solder per pin must not exceed 10 seconds. The solder joints should be in accordance with IPC A 610

Rev D (or later) – Class 3 to ensure an optimal connection between the module and gate driver board.

The module plus driver board assembly must be further supported by securing the assembly to standoffs

via the 9x Mounting holes shown in the figure below.
