How to get an pick and place file from Orcad Layout

[Charlie E.]

Hi All,
Just a quick question to any Layout experts out there. Is there a
good way to get a placement file for pick and place from Layout? The
format I need is just part, package, and X-Y coordinates of the
centroid. I think the component list is actually based on pin 1, not
the centroid of the part...

Thanks,
Charlie

Auto | Create Reports, select the reports you want. These will report
the pick & place location of each part. Since version 7, I haven't had
any problem with the report. I generally send the following off to our
assembly house (check boxes 2 thru 6):
Comp Bottom SMT
Comp Bottom Thru
Comp Insertion
Comp Top SMT
Comp Top Thru

The units in the reports will be the same as your display units
setting (CRTL-G). You can change this at anytime without harming your
board. Don't change the workspace settings in the middle of your
layout as that is a mild disaster.

When building a component, Layout has two datums, the component insert
point for the Layout program (usually pin 1, but I like the centroid
for certain parts) and the pick & place location. I put the pick &
place datum at the physical center of the part. For symmetrical parts,
you can do a right click to put the pick & place datum in the center
of the pin grouping.

To edit your datum points in the library editor, Tool | Dimension |
Move Datum. To center or move insertion (pick & place) point, right
click in the design window to show a menu with options.

When using stock parts from the Layout library, I always move those
parts into one of my custom libraries and modify to my liking. Bad
idea to use the supplied library parts without modification. I'll
rename the part with a .XX (use your initials for the XX) at the end
of the part name so I know that the part has been vetted.

I am a PSpice expert, not a Layout expert, so there are a lot of
things I still need to learn.

Just finished adding solder paste layers to my custom parts this
morning, as I hadn't even known what that layer was in the setups!

About solder paste, if you have parts with large thermal pads, like a
D2PAK or a QFP with thermal pad, use 50% to 70% (I usually use 60%)
solder paste coverage. I do this using a number of paste
rectangles/squares scattered across the pad area. Draw this with
object | copper area.
