# Layout created with PCAD 2006 CAD programm; 
# All layers are seen from PCB top side;
# All Gerber dimentions are in INCHES;
# Gerbers in G54 4.4 (incl. apertures) format;
# Gerbers include pad info as in RS274-X format;
# Plane Swell and all other swell options are disabled into the PCAD CAD tool;
# Auto remove silk over pads is always needed and/or allowed;
# Auto remove silk on via's off (if possible);
# It is STRICTLY FORBIDDEN to alter pad shapes.
# It is STRICTLY FORBIDDEN to alter PCB breaking edges and their locations.
# Holes <= 0,1mm are no real holes: Negate them.
# Mounting Holes with thin copper on them: Please remove copper
