Good afternoon and good morning. I’m Bing from Wiwynn.
Before starting to explain our design packages, please let me apologize first.
I feel so sorry that last month I misunderstood the confirmation mail and missed the IC review meeting.
Today I’m very glad that we still have a chance to explain our designs of Leopard, so I invited more Wiwynn’s experts, our PM, EE engineer and ME engineer to answer every questions.
We will tried our best to show the key of design and if you have any questions about every details, please kindly let us know.
Thank you.
