Re: Mixed part types with multi-part components?

#11905

Ah, yes, this one had me tearing my hair out a few weeks ago.   The key to it is the button on the far right of the library editor marked with a crossed-out black pin and a red pin, "Edit pins per part or body style (Use carefully!)".   I can't remember if it has to be 'up' or 'down' to get what you want, so you'll have to try both ways :).

Regards,

Robert.

For the past two weeks, I have buckled down to create the parts
libraries I need. This seems to be a nightmare for every program I
try, like they assume the parts you need are already there.

I have made some multi-part profiles which have turned out well. The
problem seems to be when I am making a component which has multiple
parts, but they aren't all the same. For instance, tonight I am
trying to make a big library of transistor and diode arrays that I
use. Now I am trying to enter a device (THAT 340) which has two NPN
transistors, and two PNP transistors. I define pins 1-3 as NPN for
Part A, but then when I define pins 5-7 as PNP for Part B, I go back
and it has overwritten the PNP for PART A also! I cannot imagine any
reason why this would happen. They have their own pin numbers! If I
change the part for pins 5-7 why would it assume that I am changing
pins 1-3 which I have already done?

The only workaround I can think of for now is just using a monolithic
block and naming the pins for the whole device. It's easy, but it
makes the schematics messy. Any ideas? Am I missing something here?

Thanks!

Hey all,

I am about to order my first double sided PCB.
a question about the solder mask. What is the normal procedure:
should pads normally be on the mask_front and mask_back?

I am asking this because I have quit a few pads that are only on one mask.Entities on the mask layers show where solder mask *won't* be so, in almost all cases, the solder pads for through-hole parts will appear on both the top and bottom layer. Exceptions would be for things like the tab on horizontally-mounted linear regulators.

Surface mount parts will, again in almost all cases, have masks on only one layer. A few may have through-pads to heat-sink areas on the opposite side.

That reminded me of the problem - it's obviously still the same.

I've just had a quick play and I've reminded myself of the way to do
things. It's a bit annoying but this is how to get around the problem

set things up as before, with the correct number of parts.
The edit pins per pare should normally be selected.


Now select the part you want to edit.

select a drawing tool, and click ONCE to start the tool. Then RIGHT CLICK
and select the edit rectangle/line options.

untick the shared by all parts in component button.

That should do the trick. Once set to this mode it will usually be
remembered but you do need to do this each time you start a new edit.

You can also change the setting once drawn. Select the general pointer
tool, the arrow at the top of the right hand toolbar. The RIGHT click on
a rectangle or line that will bring up a zoom / move sub menu. right
click AGAIN in the same place and you will get the rectangle / line
options from there you can select the shared on all parts button again.

(What happens is that the first click assumes that you want to zoom the
page etc)


If you have lots of lines then this is a bit tedious and it's better to
start off the process with the correct settings. However I have not found
a way to copy blocks between parts from the editor, so if you do have
some common graphics the it is sometimes easier to leave the settings as
common to all parts, then go into each part, switch off that option and
make the tweaks from there. This could do with a bit of work done on it
to make things easier...

It can be done fairly easily.
I created a relay symbol that had the coil and contacts as sep parts.

In the component properties you need to set the number of parts, I expect
that you have done this for other parts you have created.

Then you can start editing the component. In the top toolbar there are
two boxes, one to select the part A, B, C and so on. then a box for the
name. Next to that box is a button "edit pins per part or body style"

Click this so that it is active. this setting allows you to use
different designs and pins for each sub part.

If I remember correctly there was a small problem in getting things to
edit correctly, and what I did was to just put a single line on all
parts (with the edit pins button unselected, then switch it back on and
I could then edit things as normal.  I've not tried to do this with my
current version of kicad,  BZR 3256, so that little problem may have
been sorted out by now.

Re: Thermal vias under bottom pad of QFN64

#11899

I have uploaded a number of modules, including QFN devices, here:

Some are for projects that never got started (or the chip changed), but the others have been used successfully.   The bottom line is check, check, and check again before using *any* footprint.   Watch out in particular for QFN packages that have ever-so-slightly different pin pitches - the IPC names I've used incorporate the pin pitch in the name.

Robert.

Re: problems running on Windows XP and Mac OS X

I am in VB on a Mac OSX 10.6, 2.26Ghz MacBook (not pro). VB is running XP SP3 (which I think only uses one of the two CPU cores).

Under 7 seconds from starting the program to getting the main program window, then after I select eeschema it is just over 9 seconds before the schematic comes up (this happens to be a fairly small design). Other stuff is running at the same time, but nothing crazy. I wouldn't call that wildly fast, but for my poor overworked MacBook, it seems OK.

I am new to Kicad, so hopefully the following issues are user error.

I use a Macbook Pro 17 with Snow Leopard, and Windows XP sp3 running in a VMWare Fusion virtual machine.
I have Kicad build 3256 on Windows, 3411 on the Mac.

On the Mac version:
Eschema does not render the drawing properly, traces and components end up in seemingly random places that are not where I put them.

In WinXP:
Kicad, and all its launched tools take a long time to start, up to 2 minutes at times. Once started they run smoothly with no notable delays.
PCBnew 3D view crashes windows, specifically windows locks up in a manner that requires re-booting.
Wings 3D (ver 1.4.1) appears to work with no problems.

Kicad seems to be a very good tool, I appreciate the time and work that created it.

Thanks for any help on the issues.

Subject: [kicad-users] problems running on Windows XP and Mac OS X


??
I am new to Kicad, so hopefully the following issues are user error.

I use a Macbook Pro 17 with Snow Leopard, and Windows XP sp3 running in a VMWare Fusion virtual machine.
I have Kicad build 3256 on Windows, 3411 on the Mac.

On the Mac version:
Eschema does not render the drawing properly, traces and components end up in seemingly random places that are not where I put them.

In WinXP:
Kicad, and all its launched tools take a long time to start, up to 2 minutes at times. Once started they run smoothly with no notable delays.
PCBnew 3D view crashes windows, specifically windows locks up in a manner that requires re-booting.
Wings 3D (ver 1.4.1) appears to work with no problems.

Kicad seems to be a very good tool, I appreciate the time and work that created it.

Thanks for any help on the issues.

Hi Eric,

I find Kicad on Mac OSX to be a poor performer, and there is also a graphical glitch on the circuit diagram app. But apart from that it opens circuits OK if the library is correct.

One possible advantage of the Mac version is the postscript > PDF conversion of plots looks smoother than the other OS's.

You could try running it under VirtualBox with a "light" Linux distros. I run Mac OSX 10.7/VitualBox with Ubuntu mint. It takes 45 sec to get from virtualBox <double click> to the Kicad project screen. You can disable login password (no point in guest OS!) to a save a few seconds.

ah,ok - I will try this tonight. It's been several years since I used Kicad and I didn't recall this little step. This must be the first time I had a situation like this.

I guess then next time on bigger designs, say when using FPGA's, I might just add fanout connections with testpoints pads for the unused pins. That's normally done with BGA devices for those last minute modifcations :)

I'm not sure if this is a wise step. But it's kind of confusing to see
all of these messages about pins which I'm not using in my design.

I tried to edit the rules in the ERC options by changing the 'No
Connect' Rule on the last row from 'E' to 'Green'

But it still doesn't ignore them. These 'no connect' messages are simply
output pins which aren't used in the design.

Is there something else I need to change ?
