Table

This list is full of FIXME's, I'm not sure if anybody's working actively on those. I was going to implement a table of capabilities/etc. but then I saw that several fabs have all sorts of special case mentions. Perhaps a subset could be used; the user can always go straight to the fab's website/page to find out the nitty-gritty. Question is, though, what subset should be included?

A specifically difficult metric is pricing comparison. Two layers vs 4 layers vs 6 layers vs 8 layers etc. makes for a quickly-expanding table of hell. Perhaps 3 typical cases could be suggested next to a 'square inch' which seem ubiquitous, and each calculated at each fab, as an indicator only. For limited cases, a fab could be listed on more than one row (e.g. BatchPCB's 2 layer vs 4 layer differences).

Below is an example/test table to play with.

Fab	Layers	Traces	Annulars	Spacing	Clearance	Drill	Vias	Mask	Silkscreen
BatchPCB 2-layer	2	8	-	8	X	20-500	Y	red?	-
BatchPCB 4-layer	4	6	-	6	X	13-500	Y	red?	-
DorkbotPDX	4	6	7	6	15	13-260	Y	purple	~200
Pad2Pad (low cost)	2	8	-	-	-	20-	Y	green	~167

Transposing the rows/columns may be a better layout choice, though that will most definitely cause horizontal scrolling, and is a lot more difficult to edit. And apparently there's no method to sort the columns by a given row. Darn :)

Fab	BatchPCB 2-layer	BatchPCB 4-layer	DorkbotPDX	Pad2Pad (low cost)
Layers	2	4	4	2
Traces	8	6	6	8
Annulars	-	-	7	-
Spacing	8	6	6	-
Clearance	X	X	15	-
Drill	20-500	13-500	13-260	20-
Vias	Y	Y	Y	Y
Mask	red	red	purple	green
Silkscreen	-	-	~200	~167
