TDK-Lambda saves space in power supplies

Devon-based power supply maker TDK-Lambda has patented a space and cost-saving method of heat-sinking power components.

In particular, it applies to a daughter-board with mixed surface-mount (SMD) and through-hole components, that is soldered vertically into into a horizontal power supply motherboard.

The reason…
