SMT Fixed Jumper Links

SMT Jumper Links

The easy solution to expensive PCB design - how to eliminate additional PCB layers.

Jumping PCB Tracks

Designing PCBs is a tricky task - trying to make all those tracks fit on a single plane and not cross each other can sometimes prove to be impossible. The convention is currently to place vias on the PCB and add a second layer on the reverse of the PCB. Or worse - add a mezzanine layer to an already double-sided PCB.

Adding a 3rd Dimension

This can be frustrating to a designer if it is only a few tracks that cannot be routed on the primary layer. Fixed SMT Jumper Links provide a simple solution - use the 3rd dimension and take the track off the PCB into the space above. Jump over the tracks in the way, and return to the primary layer. The cost of the "jumper layer" can then be eliminated.

The analogy is like the road network - it's simpler and more cost-effective to install a bridge than a subway or tunnel.

Zero-Ohm Resistor

These jumper links also provide the same function as a zero-ohm resistor, using a physical package to connect PCB tracks. The advantage of Harwin's SMT Jumper Link over established zero-ohm resistors is the simplicity of the design and their ability to carry significant current. This makes them an ideal solution where high currents need to be moved around a PCB.

This property also makes them suitable for use as a contact pad, where they are more able to resist wear than a direct contact onto a PCB track. This is particularly useful in high current applications where PCB burn-through can be an issue.

Automated Assembly

The links are supplied in conventional tape and reel packages, have an easy-to-access flat area for vacuum pick-and-place nozzle, and can be surface mounted in the same operation as the rest of the PCB. All these advantages make the SMT Jumper Link a cost-effective solution.
