I’m having my first foray into 1206 surface mount - I want to avoid at all cost going double sided pcb & any drilling, so I’ve routed best I can on a single sided board - I have a few air wires left that I’m faced with soldering wire links between unroutable tracks. Now it strikes me if there was such beast as a SMD link to bridge over some tracks…I’d be laughing (but there doesn’t appear to be, so I’m not) If it’s a small ‘jump’ I can use 0R 1206 resistor, but if it’s a larger ‘jump’ needed…I’m faced with little pieces of wire.
those two air wires - particularly the one on the right - a 0R is going to be too small here, yet a link of wire is going to be fiddly - the distance is about 1cm (just under 1/2")
I’ve considered using SMD fuses - which are a good bit bigger & would 'bridge/link nicely, but at about 70p ($1) a fuse, that’s an expensive way of bridging!

0R “resistors” are available for use as jumpers. I just use wire links on my home-made PCBs.
Perhaps I didn’t phrase my post very well…I already use 0R 1206 resistors for small 'jumps …but does anyone have any top tips for anything they use for slightly longer ‘jumps’ where a 1206 0R resistor would be too physically small?
theatrus:
Expose the copper (no mask) and use actual wire?
Throughhole parts/jumpers would also work well.
That’s actually a top tip - ie buy a whole heap of ‘through hole’ 0R resistors - the body of the resistor will provide the ‘bridging’ (and stop the it’s solderable end links shorting across the tracks it bridges) …shorten the legs with some snips - solder… job done
cheaps as can be to, at less the one british pence in quantity…

There are large sized SMD resistors if you to span a larger jump. Maybe use a 2010 or 2512 size.
Get some small teflon tubing, cut it to length and thread it over some smaller silver plated or solder tinned wire. That will make an insulated jumper easier than stripping wire.

I think you’re imagining something like this: [952-1474-1-ND[/quote]
That is clearly the right answer.
I’ve never seen one in the wild though. With two-layer and multilayer boards there’s not much of a need, and from what I have seen the majority of ultra-low-cost products that are built commercially on single layer boards tend to be through hole designs. So I was surprised to see that it existed - I’ll have to keep that in mind, it may be just what I need someday :)](Electronic Components and Parts Search | DigiKey Electronics)
