PCBFabexpress Green Boards

Tonight i got some great feedback on the appearence of the keychain device.  Specifically, they liked having the look of the green pcb.  To see how much we could get the cost of the pcb to using a PCB board house which applies the green lpi solder mask i priced out several board houses.

PCBFabexpress offers a deal where you get a board for $13 per board (min quanity 5) and the board can be up to 20 sq inches.

Each device is 1"x2.5" which means we could panelize them on a boardand get 10 on one board and then we'd just have to use our CNC machine to cut the larger board into smaller boards.  But to take intoconsideration the 1mm router bit width it's safe to say we'd only getabout 9  boards out.

So the cost per board is $13/9 which is $1.44

The minimum order requirements would make it so we'd get 40  boards for $65 dollars + shipping.

I found a much cheeper board house: Olimex they sell you a panel thats 12.6"x7.8" for $104USD.  We could fit at most 35 boards on the panel so it'd cost us per board 104/35 =$2.97

  1. In order to get the best deal with them we'd have to try to make the following optimizations:
     reduce the number of holes but most importantly the number of hole sizes.
  2. if possible make trace widths greater then 20mils so etch resistsingle silkscreen printing can be used rather then dry film lamination,exposure, developping


Bare Bones PCB:

1000 boards would cost $1.59 a piece but would be precut.  But no solder mask.
