<p>A modified aperture shape (112) for screen printing eliminates insufficient solder without increasing the number of solder bridges. The shape is narrow in the area where the component lead will touch (100) and wide or overprinted in the area where the lead does not touch (102). To further increase solder volume the length of the aperture can also be overprinted. The overprinted areas provide greater solder volume, while the narrow area where the lead will touch prevents solder bridging.</p> |
