Critique on PCB layout wanted
mc172:
Some of the tracks are very close to the pads. Make it easy for yourself - if you had to hand solder that, you'd probably short out pins 14 to 19 on the larger IC because of the tracks needlessly close to them.

Wouldn't the solder resist prevent this?

What is wrong with length matching? Its good practice so is CMRR.
why encourage a lazy attitude?
If your gonna say don't do it at least give a analysis number on the protocol degradation %. Instead of doing basic communications engineering calculations to educate you just call some guy a noob. wtf
the fact of the matter is, it may work, but at what capacity and under what conditions, how does interference susceptibility change based on mismatch, all sorts of issues can be analyzed here instead of answers like that
Simon:
Right, thread sort of tidied up, now play nice please!

Yes, if you get a board made rather than roll your own. There is nothing forcing the tracks to be so close to the pads so why make it more difficult than it needs to be and rely on the solder resist?
