Board Outline
Precise board perimeter routing details:
Our process will program the board routing automatically by reading the path of
your outline. The outline must be a continuous line; round or odd shapes okay when
following our guidelines, although the shape should be very simple to be considered
for the Quickturn Service.
Our overall board dimensions are calculated from the center of the traces used to
draw your board outline.
You should leave a .020" space from the fab edge of the board to the nearest
copper elements to prevent traces from being cut off and possible mask peeling and
exposed copper.
Most board shapes are allowed, however, due to the restrictions of our service,
please check your outline for compatibility prior to submitting your files so there
are no disappointments.
Restrictions:
- Limit to 1 pass of outside board perimeter using .093" router bit; no internal
cutouts.
- No internal cutouts, tab routed (array) pallets, v-score or slots
for Quickturn-Proto services -- If your needs exceed our quickturn proto boards,
try our full-featured quote.
- Connected or Panelized boards are not cut apart, you will need
to cut smaller boards from main panel. We recommend a Dremel tool, rotary cutter
or small saw for separation. A continuous outline must be placed around individual boards connected with tabs;
channel widths between boards must measure no less than .110 between boards otherwise
a default square/rectangle may be placed unless you specify to hold for outline
redraw.
- Break away or Perforation Holes: Please limit your total number
of holes per board design to no more than 35 per square inch.
For example; if the total area of the circuit board is 9 sq-in, there is a limit
to 225 max holes per board. For designs exceeding 35 holes per sq-inch there may
be an added surcharge of 10%
- Inside Chamfer not recommended (an inside cut made usually at a
45° angle to the adjacent edges).
Non-Continuous/Odd or Difficult Shapes:
Odd or difficult shapes are defined as broken lines, overlapping lines, and/or improperly
drawn arcs. We reserve the right to change the board shape to a default 0.0 square
or rectangle snapped to the existing board outline IF the board shape is
difficult or not a continuous line. No Hold or Alert notice will be sent unless
you specified on order form to "hold the order for outline redraw."
Missing Outline:
If outline is not present on the layer specified on your order form your design
is processed as sent. We will create a square/rectangle outline .020" from
the nearest copper feature if outline is missing.
No Hold or Alert notice will
be sent unless you specified on order form "hold the order for outline redraw."
