# Content: MacTavish Standard Aperture List
# Date: Wed Sep 26 22:29:00 1996 EDT

# This list establishes the MacTavish standard assigments of
# aperture purpose, shape and size to Gerber D codes.  Once an
# assigment has been made, it is very important that the
# assigment never be changed.  If additional apertures are
# needed, assign those apertures a unique D code.  Printed
# circuit board manufacturers are likely to assume that a given
# code is used for the same purpose from job to job.  Reassigning
# a D code is almost certain to cause the improper manufacture of
# a board.  PCB manufacturers should always be certain that they
# are using the current version of this table.

# Systematic aperture codes:
#	D1sss - Flash aperture codes
#	D2sss - Draw aperture codes
#	D3sss - Drill aperture codes (finished hole size)
#	where sss is the aperture size is mils.

# Flash codes (pads, etc.):
aperture	D1040	40	round	flash
aperture	D1050	50	round	flash
aperture	D1055	55	round	flash
aperture	D1065	65	round	flash
aperture	D1070	70	round	flash
aperture	D1080	80	round	flash
aperture	D1128	128	round	flash
aperture	D1150	150	round	flash
aperture	D1200	200	round	flash

# Draw codes (traces, text, etc.):
aperture	D2005	5	round	draw
aperture	D2006	6	round	draw
aperture	D2010	10	round	draw
aperture	D2012	12	round	draw
aperture	D2015	15	round	draw
aperture	D2020	20	round	draw
aperture	D2025	25	round	draw
aperture	D2030	30	round	draw

# Drill codes (finished holes, etc.):
aperture	D3020	20	round	drill
aperture	D3030	30	round	drill
aperture	D3040	40	round	drill
aperture	D3080	80	round	drill
aperture	D3157	157	round	drill


# Traditional Gerber aperture codes
# These codes are compatible with the codes used with the traditional Gerber
# 24 aperture photoplotter.  Codes are assigned from the following list:
# D10,D11,...,D19, D70,D71, D20,D21,...,D29.

# These codes were used in PCB-MANCON-002, but are obviously becoming very
# disorganized.  The should not be reused, because we may produce more
# PCB-MANCON-002 boards in the future.
