    how to make Die bonding IC package? Reply

    I have few questions to ask here(I am a new user), much appreciated for your help.

    1. How to make Die bonding IC package? I have pad coordiantes. Doese I need use Allegro package design tools? or the general Allegro PCB designer is enough?  Because I found my company floating license is limited for Allegro PCB design.

    2. when i import DXF file as my PCB board outline, but I found the size is zoomed out, the actual size is only 1/8, so what's the reason and how to solve it?

    Thanks,

     >1   Is this a IC package design, or a PCB COB (chip on board) design?

    >2  Check the units (mils, mm, um, etc)  on the content you are importing versus the target database.

     Thanks Bill

     

    1.  is PCB COB,  i have a question about the solder pad,  i should creat the solder pad  when I creat die symbol?   or I can creat solder pad on PCB board designer by manual placing?

     2.  I select the same units, but I found the size is not the same as esolidWroks

    3. what is the folder or lib directory of general PCB package? such as 0402, 0603etc.  I checked the  pcblib\symbols  , but i don't which one is package of 0402, 0201. 

    Thanks for your support.
