When mounting MicroModule, the suggested clearance for the cut-out around the actuator is 0.5 mm and 1.0 mm for the click buttons. To panel mount the module without sealing, fabricate a panel designed with the necessary cut-outs for the actuator and click buttons, and four or more fasteners (PEM studs, edge clips, hole clips, and heat stakes). When installing, MicroModule should be seated evenly and the fasteners tightened evenly to avoid stressing the printed circuit board. Over torque on the bolts should be avoided, this could crack the PCB and cause the module to fail. It is recommended to use a PCB support bracket to apply even clamping pressure to the MicroModule unit. With proper seating and tightening, a liquid and particulate resistant interface can be created.
