I have an 8.4" touchscreen that I amaking a custom enclosure which will slide into and out of a single DIN enclosure in my car.
So I have cut a plexiglass back wall on which I was going to mount my VGA controller, inverter and touchscreen controller. Everything is separated from the plexiglass by brass standoffs and one leg from each is connected to ground. The inverter is also surrounded by a plastic "garage." My screen is shielded by a thin metal sheet across the back (since I am worried about noise from having the components so close. But the whole thing ends up too thick to fit into a single DIN enclosure (it is over 2.11 inches thick). I want to mount the components on the metal shield (thus the components would "face away" from the back of the screen) as described below to save more room - this is how it would go:
Screen -> metal shield -> components attached to metal shielding (with brass standoffs and grounded) -> plexiglass back wall.
If I mount the components on to the metal shielding instead of the back wall, I can save at least a quarter to half inch, if not more.
Will this work - if not, why?
My main concern is the inverter and arcing - should I put a plexiglass piece between the inverter and the metal shield (with standoffs, grounding, etc.? Should I even be worried about this if I have everything grounded?
I am almost there and really want to finish this week - any help would be greatly appreciated. I basically need to get this as thin as possible. I figure that they those pop up screens from Pioneer, etc. must have an inverter stuck in there somewhere close, so why can't I.
I also have placed a sunon 5v fan into the back wall to keep everything cool (necessary?).
