  • New 16.6 Off-Angle Slide Behavior
    I've been using release 16.6 and general like the improvements made to the slide routine.  However, I'm having a lot of problems with the new off-angle sliding behavior.  Most frequently, I've found it when I've moved a component with the slide net option on so it creates an off angle segment coming off of the part. ...

  • Re: Capture to Allegro PCB (no connect) pin question
    You can edit the schematic symbol and add a property called "NC".  Put the pin number in the value field and it will be considered by PCB Editor as a no connect.  If you had multiple no connect pins, just put them in the value field as a comma-delimited list with no spaces. Matt M.

  • Re: Can't move small jogs in trace into pad
    It looks like "Enhanced Pad Entry" has struck again.  When you are in Add Connect or Slide mode, right click and look for the "Enhanced Pad Entry" line.  While this is checked, it is going to force clines to come out of a pad at a 90 or 45 degree angle.  If you deselect this option, it should act as the ...

  • Re: RE: How do I make holey (perforated) thermal ground pin?
    DrL, Erivas method works very well, but I would add one caution on that process.  You must be careful in creating that power pad shape because of what needs to be exposed copper and what should be covered by solder mask.  If the entire power pad shape is left void of soldermasking, then you may be hard to get the right amount of solder ...

  • RE: How do I make holey (perforated) thermal ground pin?
    The callout to the upper left of on page 109 of the first doc indicates 49 holes with a diameter of 0.25mm.  The similar situation is on page 23 of the second doc with a callout indicating 5 holes of diameter 0.3mm; look at the “Exposed Pad Geometry” blow up at the lower right. Hope this helps. Matt Messinger

  • Purpose of Tooling Corners?
    Hi Everyone, We have some older boards that contain tooling corners.  On these boards, they are placed at the corners (of course) and spaced slightly outside the board outline.  Previous vendors have ignored them while another is using them to define the board extents. Can anybody tell me: 1) What is the purpose of the tooling ...

  • Unknown Shapes on pins
    Hi All, I was wondering if anyone could explain the triangle shapes I'm seeing on the pins in the attached picture.  They are attached to only two pins of one package and I can't find out what they signify.  The other pins of this part do not have the shapes but they are the same padstack, so it ...

  • Re: Help with "FIXED" property
    You can try using the Unfix toolbar item (or type "Unfix" on the command line), select Comps in the Find Filter and then select the symbol that you want to unfix.

  • Re: How can I make a package with two pads shorted together?
    The problem is that the via is a mechanical pin which don't have any logic attached and is giving you the DRC.  Make the via a normal signal via by using Add Connect in the symbol editor.  When you bring it into the layout it should then take on the net of the trace.  Matt

  • Re: How can I make a package with two pads shorted together?
    We've done this type of thing many times.   Although the DRCs show up while editing the symbol, they will disappear when you bring it into the board.  The errors in the symbol editing occur because there is no logic in there to support connecting different pins.  As long as the schematic shows that those two pins should ...
