[GM5: Least-cost USB-MIDI Interface Chip for 4.50 EUR]

I'll add some bucks onto the Paypal payment for my chips & boards if that's OK. No reason why you should take the hit for this.

Yep :) batchpcb.com (which is the fab placed I used) does have a nice how-to on setting things up correctly in Eagle, but it doesn't include the design rules - rather it includes things like how to properly silkscreen the thing and output it into the proper machine files they use. Oh well :)

What are the PCB rules and limits?

2 or 4 layer boards - 0.062" FR4 material

2 Layer sizing:

8mil spacing minimum

8mil traces minimum

20mil minimum drill size

4 Layer sizing:

6mil spacing minimum

6mil traces minimum

13mil minimum drill size

500mil maximum drill size

No internal routes' date=' no v-scoring

Board is routed to the indicated border (very clean edges, you can get creative with the shape as well!)

Soldermask both sides

1oz Copper

No limit on the number of vias

No limit on pads or components

Multiple designs, multiple copies are allowed!

Any size up to 10x15", measured in inch increments

Minimum billable size 1x1" (smaller boards are allowed but rounded up)

Your design can be any size - board size is rounded up to the nearest inch
