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 :)
