    Friends,

    My "boss" ask me to wire-bond an IGBT chip with Al wires. I never did this before, and I even do not know what's on the surface of the chip. I checked the internet and find some example, like this page:

    http://www.techno-fandom.org/~hobbit/cars/ginv/i2compon.html

    The chip that I need to bond is shown in the attached picture.
    My question is: 1) What's the meaning of those different "channels" or "columns" on the chip surface?
    2) Do I have to bond one wire on each "channel" like those shown in the website pictures?

    I am not an EE guy, so ...
    Thanks!

    What you do is to go to the manufacturer and get the data sheet for that IGBT chip. It will identify the structures and bonding pads. You may be able to get to it online. Your "boss" should have provided you with that data.

    regarding to your question, you should also consider that the reliability of Al wire bonds depends on the
    bond strength between the Al wire and the IGBT chip.
