'[EE]: Working with or-cad layout.'

Hello,
     I've been learning orcad lately and I'm having two very
frustrating problems.

1.  How do I Turn off all the extraneous text?  I only want it to show a
resistor name say "R2", not that it's a "0805" and a resistor.  :)

2. and how do I make a board only double layer not 4 layer?

Thanks to any orcad guru's out there,
Aaron

Sorry, using orcad 9.2 (not lite, if this matters).

I just click on the value not the part, then right click on the pink
highlight. Click on "Edit properties" and a menu will pop up and you can
set it to invisible or other. I'm still looking for an initial default so
I don't have to do it to every part.

Not sure about the layers though. I don't use this version much unless I'm
doing subcontract work for a company I work for and they require this
program. There is a very good tutorial if you go to "Help|Learning Capture"

Thanks for your help Rick.

I got so frustrated I just deleted the text from the footprint.  :P

To solve the layer thing I just editied the layer and changed it to no
route.

I'm not sure if either of these are correct procedures but hey it
worked.  :)


Anyone happen to know how to place components on the bottom side of the
board?

You probably just want to make the whole layer invisible. Click on the
colors icon on the toolbar, select the layers you want to make invisible,
and click visible<>invisible.

Select part, right click, opposite (using the menus). Look up the key
commands in the manual or set your own to go faster...

Thanks Spehro,
             I just noticed also that every part appears on both the
top and bottom layers.  Do I have to actually edit the footprint (and
delete the specific unwanted layer) of every part to only have it appear
on one layer?

What do you mean "appears on"? There may be bits of a part on various
layers, but each entity is on one layer at a time (or the global layer).

In the case of pins, you have to edit the padstacks or create new ones
to have them appear on only one side, they typically have bits on each
possible routing layer. Normally you want pads on both sides, though, or
you can just not output the top layer if you want. Typically pads
designed for double-sided boards are too small to be reliable on
single-sided designs, though.

Spehro,
      I'm trying to use SMD components.  When I created the padstacks I
did it by the method described in the help file.  I went, select from
spreadsheet then esc then new.  Created it the size I wanted etc.

The problem I having is the pad appears on all layers and since it's smd
I want it only on the topmost layer.  But I can't figure out how to
delete the extra pad stacks.

Thanks for all your help,
Aaron

Sure your not looking at the solder paste, solder resist layers?

Typically you'd also want it on the top solder mask layer, perhaps a bit
larger. To get rid of the pad on layers where you don't want it (all the
others for an SMT padstack), just set Pad Shape to "Undefined" for those
layers.

You must select the right footprint for your components. If it is a
surfacemount component, use a footprint for surfacemount.
If its throughmount use a throughtmount footprint.

If you use a surfacemount footprint it will only appear on the side
you place the component in layout. And ofcourse througmount
components will be on both sides.

There are some exellent short lessons in the help menu
for the basics:-)

And if you happens to find out howto change the size of
a single pad in layout gimme a buzz !

If you double click on the component in the schematic then the properties
page comes up. One of the properties allows you to select which side of the
board the component mounts. This allows you to force it to the reverse
side - the entry is probably blank initially. Look for the heading
"COMPSIDE" and put "BOT" in the field. Check Help for the options for the
field.

P.S. I use Capture CIS, but I believe Capture works the same.

I forgot to add to this that if you right click on the headings in this
properties page it will select all fields in that column and allow you to
edit them all at once - useful to change a bunch of components from top to
bottom at the same time.

You can also use this page to deal with your other request - turning off the
display of fields. When you right click on the heading one of the options is
"display". select this and there are radio buttons, one of which is "do not
display".

Hi,

Chose the tools "pin", and click on your pad, in  the tool bar you see the
ICON look same spreadsheet click and go to the  PADSTACK,

Select all layer you don't need, make "CRTL+E"  and select "Undefined" in
the box "Pad Shape"

Patrick,
       Just go into the footprint editor and create a new padstack in
the manner described in my last mssage (obviously of the dimensions you
want).  Then simply double-click on the padstack you want changed and
select the new padstack.

Thanks to all that helped, especially Spehro, I think I got a hanle on
this program now, I've done the lessons but I just couldn't seem to find
out how to do some of the basics.  :)

Thanks again,
Aaron
