摘要:
Micro solder joint and stencil design. In one embodiment, a stencil for depositing solder on a printed circuit board (PCB) includes a plurality of stencil apertures, a first stencil aperture of the plurality of apertures having an aperture wall defining an aperture perimeter. The aperture wall is configured to not extend beyond an outer edge of a PCB pad provided on the printed circuit board, the aperture wall is also configured to not extend beyond an outer edge of a terminal of a surface mount component, and the first stencil aperture is configured to receive solder paste to form a non-convex solder joint between the PCB pad and the terminal.
