connecting 2 or more pads to 1 pin.

[jahinbaha]

for Version 1.4

I am making my own library for components.
I need to connect 2 (or more) pads in the pattern to 1 pin in the schematic.
For example a Triac in SOT-223 package has the com connected to 2 pins.
How can this be done?

Thanks for your help.

This cannot be done in version 1.4, but is able to do in ver.2.1.

Open "Attached pattern" window in Component editor and choose a pattern for the component. You will see blue lines that connect component's pins with pads. Using mouse, you can add extra connections from unconnected pads to already connected ones.

I'm using DipTrace 4.3.0.5 on Windows 10.

I tried this, but it doesn't work for me. It appears to think they're connected when I drag between the two pins. If I try it again it asks if I want to disconnect them, so obviously the "connected" state is recognized. I also see a little red line between the "connected" pads.

However, when I route the board using this new component, it doesn't connect them with real copper!

If I do a CHECK NET CONTINUITY, it seems to think all is well

You can see the tiny lines that seem to indicate there are RAT lines to be connected, but the router doesn't see them.

I'll byte, what am I doing wrong?

The blue dashed lines are not ratlines; they indicate a component's internal connection(s) and are not related to external traces.

OK, how do I internally connect the multiple pads in the component definition, or is that not possible?

This can be accomplished in the "Attached Pattern" dialog window of the Component Editor. If the pads have identical numbers they will be automatically connected. If they have differing numbers simply drag a line between them. To remove an existing line, drag another line over it to bring up the appropriate context menu. All connection lines in the "Attached Pattern" dialog window will be solid, thin and red (default color). Curiously, internal connection lines will show as blue and dashed in the PCB Layout editor.

I did exactly that, but when the board was routed, no copper exists between the internal pads. In my previously posted graphic, you can see the thin red lines.

If you need external traces between the pins, just manually route them.

I figured I could do that, but truthfully I didn't notice they weren't there, I didn't realize I had to route them myself. The point of putting them in the component was so I wouldn't forget to route them.

I'm guessing I should forget about putting them in the component...
