Abstract:
Meeting todays requirement in power supply technology demands significant technological advancement in optimizing circuit topology, components and materials, thermal and packaging designs. These requirements are being pushed mainly by continuously increasing power density and efficiency requirements. Ultimately, these trends will come to a point whereby limitations from the above mentioned technological advancements is dependent on one of the above, which is the packaging design. To realize this dependence, we need to look at the growing power systems for modern equipment out there. Let us enumerate some of the available AC adapters in terms of power densities of a 45 W adapter. Firstly, square type architecture introduced by Apple is about 7 W/in3, considering the packaging has a profile limitation whereby its AC plug is removable thus occupying relatively bigger chunk of the volume. The next one is by Asus of similar profile to Apple incorporating the AC Plug eliminating the socket assembly in the packaging; which packs about 9 W/in3. Lastly, the typical rectangular profile by Eos which is about 7 W/in3. As for this particular embodiment it is about 40% smaller in profile, in contrast to the 45 W Apple packaging, with increase power density of about 12 W/in3. Packaging design method plays a great role in achieving the above requirements for a very high density converters.

The present invention provides an assembly for attaching a circuit substrate to a housing. The assembly includes a fastener having a first end and a second end opposite the first end, where the first end is larger than a second end. The assembly further includes a circuit substrate including a through hole having a first opening on a first side of the circuit substrate and a second opening on a second side of the circuit substrate, the through hole for receiving the fastener. The assembly still further includes a mounted structure attached to the circuit substrate, which at least partially covers the second opening of the through hole on the second side of the circuit substrate, wherein the mounted structure restricts the size of an exposed portion of the second opening of the through hole. The second end of the fastener, which is received in the through hole of the circuit substrate is sized to extend through the through hole, as well as the restricted size of the exposed portion of the second opening restricted by the mounted structure. The larger first end of the fastener is sized to extend through the through hole, but not through the restricted size of the exposed portion of the second opening. The assembly further includes a housing having a boss adapted and aligned for receiving the second end of the fastener after the second end of the fastener has been received by the through hole of the circuit substrate, and extends therethrough, wherein the boss is adapted to grip the received second end of the fastener.
