CONTROLLER PCB
The controller should ideally be mounted to four metal standoffs pre-fitted to the metal chassis so that
there is a good low impedance ground connection between the controller PCB and LCD metal chassis,
as shown in Figure 8. The controller PCB should be spaced at least 5mm away from the metal chassis.
CONTROLLER SPACED 5MM ABOVE METAL WORK AND GROUNDED TO METAL CHASSIS
VIA METAL STANDOFFS
If mounting via metal standoffs is not possible, double sided gasket pads can be used. The controller
PCB should still be spaced at least 5mm away from the mounting surface, as shown in Figure 9.
Any gasket used must maintain its adhesion at any temperature that it may be subjected to in service.
