Re: KPC3 -- 9600 ?

I have to agree with both.  SMT is not hard to work with.  I do less board
damage on SMT than multilayer through-hole devices.  I have Pace vacuum
desoldering equipment for through-hole and soldering tweesers for SMT.  I
use a 10x microscope to see the parts and very fine solder.  The soldering
iron is a temp controlled with 1/64" tip.  I do less damage to the board
than th contract board house that builds boards for work when they have to
do rework (abt 80 % of their boards have rwk).

SMT is east to work with with good tools. But good tools make any job easy.
