Moving Wire Bond in APD16.2 results disconnect Wire and it's Bond Finger

Alice

Hi all,

 I face problem when I want to move the wire bond in APD16.2. After the first nove of the wire bond, when I want to make second time move, the Bond Fingers will shove togather but the wires stay as it is. It seems like a disconnect between BF and wires. Does anyone know how to solve this ?

 Thanks,

Alice

  • How do you implement the bond wires? I use a sub-class under package geometry. It is then not "connected" more than visually. To move a bond wire, I then have to re-draw it.

  •  Which "move" are you using? Edit-->Move, or Wirebond RMB Move (the correct one)?

  • Hi Bil,

    I used Select>Click on the wire bond > Move. Also, I tried Edit-> Move. Both methods gave me same problem. This issue will happen after I intend to move the same wire bond for the second time.

    Pls advice.

    Thanks,
    Alice

  • Hello Jacob,

    I think you need to on the wire bond layers. Color>Bond Wire Profiles> check on the profile .

    But first, you will need to set up the wire bond profile before do connection.

  • I have heard of a similar issue before in a few designs. Are your bond wires quite short? What units is your design in? I know it might sound strange, but if they aren't in microns, try changing to microns and doing the move again. This might fix your issue. I know it has on some designs that I have seen. 

    If you've already moved the wirebonds and they've become disconnected, 16.2 has the Tools -> Package Design Integrity command. Under the wirebond folder, there is a check which will look for bond wires which have become disconnected from their finger (or pin) and will try to reconnect them for you. I would recommend trying that out if you get a second. It's not a solution, but it will usually be able to fix the design up for you so that the wirebond move command works properly again.
