A method and apparatus for depositing solder paste on a printed wiring board has a stencil with a pattern of multiple apertures. The pattern aligns with a through-hole in the printed wiring board when the stencil is in physical contact with the printed wiring board. A squeegee arrangement applies solder paste through the multiple apertures in the stencil through the through-hole of the printed wiring board to the upper surface of the printed wiring board for securely mounting electronic components to the upper surface of the printed wiring board, for providing a thermal path for the heat sinks of the electronic components and for providing a low inductance electrical path to ground for the electrical components. |
