Drill file
with tool codes and X-Y coordinates of all holes |
|
A drill report
that includes the following information for each hole
size: Finished hole size and tolerance, a range (.135"
-.142") or a tolerance (.139 +/-.003) must be specified.
|
|
Quantities for
each hole size |
|
Hole status
(plated or non-plated), ( Via, Press Fit ) |
|
Preferred Drill file format:
ODB++
Excellon Format 2
Acceptable formats:
RS274D / Trudril
|
|
The order of
holes in the drill shop report matches the order in the
drill program Drill data aligns with image data ( Ensure
common output format as Gerber ( 2.3 / 2.4 ) |
|
Plated and
unplated holes separated into two files |
|
Fabrication
Drawing Information |
|
Profile information
is used to generate a numerically controlled rout program
to finish boards to their final dimensions. The drawing
must clearly and fully describe the part profile using
standard dimensioning and tolerancing practices. |
|
Board outline
dimensions, including cutouts, chamfers, radii, bevels,
scoring, etc. |
|
Fiducial locations,
slots, tabs for break away rails. |
|
Dimension from
at least one drilled reference hole internal to the part
|
|
Hole chart with
symbols on the drawing and the finished hole sizes, tolerances
and Quantity |
|
Material requirements
|
|
Layer stack
up |
|
Finished board thickness,
tolerance, and surface finish specification |
|
Controlled Impedance
requirements (if applicable) |
|
Dimensioned array drawing
if the part is to be supplied in multiple up array |
|
Notes defining
product specifications to be used in fabrication |
|
Notes defining any special
requirements such as NFPR, thieving. Soldermask, Via cap
and/or Via Fill instructions |
