Abstract
An electronic device (100) has a heatsink (116) and electrical contacts (120) which are originally all part of a support frame (200). After assembly, the border of the support frame (202) is broken off, thereby electrically isolating the electrical contacts (120) from one another, and from the heatsink (116). The electrical contacts (120) and the heatsink (116) are coplanar. In one version, the electrical contacts (120) do not extend past the circuit board (102) of the device (100).
