[sdiy] JH goes PCB - Copper ring size for PCBs?

[JH.]

I'm editing some library elements of my Rimu PCB layout tool for the use 
with Olimex:

Olimex web site says that final hole diameter will be 0.1mm smaller than 
drilled because of plating of the holes, and consequently offer "odd" drill 
diameters as a standard, like 0.9mm and 0.7mm, to get the "standard" holes 
of 0.8mm and 0.9mm.

So, ist it ok to increase the hole size in the library without also 
increasing the pad diameter?
Specifically, is the combiantion

Hole = 0.9mm, Pad = 1.5mm ok ?

(Talking of double sided boards - I know it's probably not large enough for 
single sided ...)


Hmmm, yes ... I think I'm going to make pcbs again after many years of 
Veroboard-only.
And I hope it will be for the benefit of the DIY comunity, too! :)

And I just found that I *might* get the whole lot of filterbanks and 
envelope detectors of a Sennheiser vocoder
on a single 320 x 200 mm board, when I completely redesign the circuit 
topology ...
