Better than zero-ohm resistors, the SJ-series of surface-mount jumpers from Components Corp lets you run circuit board traces underneath to offer layout flexibility, or gain a test point. The jumpers handle up to 2A, and are made of flat copper wire that is plated with tin/lead for solderability. They are available in EIA size 1206 and 0805 packages, equivalent to 2 x 1.2-mm and 3 x 1.5-mm sizes, and come on reels of 1000 pieces.
