Default finger padstack and export .mcm to .brd

USSH

 Hi all,

Could you please let me know how to change the default padstack in APD. By default, in Wirebone Setting, there are 2 padstack (WB_TACKPOINT, WIREBONE_FINGER). Can i add more default finger padstack ?

 I create a .mcm module then place it into .brd but there are errors showing that layer inconsistence between .mcm and .brd. How can i deal with this issue ?

Thank you,

USSH

    You can add as many bond finger padstacks to the design as you like. To be available for use as a bond finger, it must be a single-layer pad on either the top or bottom surface layer (unless you have enabled cavity bonding, in which case single layer pads on those cavity layers are also permitted). You can bring these padstacks in from your library if they are there, you can make new ones based on existing finger pads already in your design using the padstack editor tool and saving them to a different name before updating into your design. While adding wirebonds, there is an "Add" button next to the padstack pull-down field in the options tab which will allow you to define a based oblong or rectangle finger on the fly during your bonding, as well. 

    With records to your other question, I do not really know what you are trying to do. If you are creating a module for reuse between one design and another, then the cross-sections need to match in order for things to work. If you are trying to place an instance of this package into a PCB under design, I think you should be using the File -> Export -> Board Level Component command, which creates the necessary library symbol, front end files, etc. for use in your PCB layout.

    Hope that helps,
    - Tyler
