Abstract
The disclosed embodiments of electronic packages include electrical contact pad features present on all sides of the package that facilitate simple and low cost electrical connections to the package made through a mechanical contacting scheme. In an embodiment, an electronic package comprises: a metal leadframe having a first leadframe portion having a first thickness and a second leadframe portion having a second thickness that is less than the first thickness, the second leadframe portion defining electrical contact pads; a silicon die attached to the second leadframe portion and overlying a space formed in the leadframe by the first and second leadframe portions; and wirebonds coupling the silicon die to the electrical contact pads. A method of fabricating the electronic package is also disclosed.
Claims14
An electronic package comprising:
- a metal leadframe having a first leadframe portion having a first thickness and a second leadframe portion having a second thickness that is less than the first thickness, the second leadframe portion forming electrical contact pads;
- a silicon die attached to the second leadframe portion and overlying a space formed in the leadframe by the first and second leadframe portions, wherein the silicon die is attached to the second leadframe portion with non-conductive die attachment material;
- and
- wirebonds coupling the silicon die to the second leadframe portions.
(canceled)
A method of fabricating an electronic package, comprising:
- forming in a metal leadframe a first leadframe portion having a first thickness and a second leadframe portion having a second thickness less than the first thickness;
- attaching, using non-conductive die attachment material, a silicon die to the second leadframe portion such that the silicon die overlies a space formed in the leadframe by the first and second leadframe portions;
- and
- electrically coupling the silicon die to the second leadframe portion.
