hello,
This is the my 1st SMT pcb etching project board.
Is there anything horribly wrong with the layout of the
components and/or traces ?
Well, it would make *me* happier if you used standard reference
designators. Q = transistor, D = diode, T = transformer, etc.
Incidentally, CR is archaic for diode, and DS for indicator
lamp. We
call all diodes D, including LEDs, and all resistors are R.
The board looks fine. A couple things are a little unusual,
like the
angled connection into R11-R12 and into R4-R5 and R13, but
that's just
a matter of style.

Thanks John,
i have incorporated lots of changes suggested.
The software package used those designations but i changed them
to suit modern style.
