How important is it to track from centre of pad in PCB routing?
With the trace offset, there's an acute angle left between the pad and trace. There's been a lot of discussion over the years about the effect of 'acid traps' on the over-etching of the copper, and difficulty of washing out of the corner after etching. It doesn't seem to be such an issue with photoactivated etching systems, so may be a carryover that's no longer as important.
