Abstract:
Bottom terminated components and methods of making bottom terminated components are provided. The bottom terminated component includes a die paddle and at least one die paddle structure configured to prevent wicking into a respective thermal via of a printed circuit board. The at least one die paddle structure includes a base defining an axis, the base having an axial thickness extending from the die paddle, and a contact surface configured to contact the printed circuit board at the thermal via of the printed circuit board to prevent wicking of solder into the respective thermal via.
