Is there anyway I can change the electrical type of a pin to one that is
not listed in the drop down menu? I would like to put an open drain on one
of the pins.

The problem is that the translator can not import the files right. I
tried to import PADS files a long time ago, and ran into the same problem.
The only way I was able to import them was in PADS version 2.0 in ASCHII
format. Even then I had layer registration problems, Traces on the wrong
I think it is in the Protel translation, I have seen other CAD
systems import the same with no problem. I have thought of trying to get
some demo software from another vendor that I know can import into Protel
w/o a hitch. I am not sure that you would be able to export a PCB with
I am currently working on a new design which I will be placing in an
assembly array. I was wondering how many use protel to set up an assembly
array? If you do set up assembly arrays do you specify coupons? or do you
let your bare board manufacture and assembly house specify them? I ask this
IPC is telling designers that documentation is something that is
determined by the designer and the board house. Some designs are so complex
they require full documentation others are simple enough that one could get
away with limited documentation. If your design is going to be

It should link you directly to IPC-D-325 Documentation Requirements for
Printed Boards, Assemblies and Support Drawings.
The only reason I brought up using inner layers, is because as we have just
found out each design requires some special requirements. I have had tracks
that where impedance controlled on inner layers, and buried passives. The

The fab house may have to add plating robber pads to keep your 5 mil

Ouch! 5 mils clearance
You can import them in if they are PCAD version 2 ASCII. You will
have layer registration problems that you will have to clean up. Mechanical
layers on silkscreen layers multlylayer pads that import as single layer,
things like that.
Try confirming that the pcb.Lib is still available/selected for those
components in your design.

I have tried this as well. I contacted Altum and there reply was
that you can not globally change them. This must be done one at a time.

I would use a ribbon cable that was previously suggested, or use a
flex circuit. Running traces to the edge of a board would cause lamination
and corrosion problems. If the copper is run through the tab and then the
board is snapped apart that copper track will be exposed on the edge.
$195 for the full package? I think I might get it for home just to do some

Have you checked that you turned on the midlayers in question? I ran
into this problem when I started using extra layers in my libraries, and
that was the solution.

use IPC 2221, and use the coupons. This will allow you to follow the build
up of layers through plating and drilling. Any destructive testing can be
done on these avoiding having to destroy a sample of the production board.

I am sure that this has been brought up many times, but could not locate
anything in the archive. Has any one had the opportunity to try and design a
board using micro via's or HDI style design methods with Protel99SE? How do
the CAM files turn out? do I have to make a ton of crazy DRC rules?
I have been given the task to add assembly drawings to a design that another
engineer is working on using protel 99SE. I would like to go into the
library that he is currently using and just add a mechanical layer 1 to each
part with a .comment string, and update the PCB from the library. There

I think what you are seeing is the crosshairs to the pad. What you are
talking about looks like they intersect at the center of the pad, if this is
not what you are talking about I am missing something else. I am sure once
you view the gerbers you will not see the voids.
