<h3>SparkFun Jumpers</h3> In this library you'll find jumpers, or other semipermanent means of changing current paths. The least permanent form is the solder jumper. These can be changed by adding, removing, or moving solder. In cases that are less likely to be changed we have jumpers that are connected with traces. These can be cut with a razor, or reconnected with solder.

Apply solder to close the connection.</p> <p>Round pads are easier to solder for beginners, but are a lot larger.</p> <p>SparkFun Product that uses the round pads: <ul><li><a href="https://www.sparkfun.com/products/12781">SparkFun EL Sequencer</a></li> </ul></p> <h3>Normally closed trace jumper</h3> <p>This jumper has a trace between two pads so it's normally closed (NC). Use a razor knife to open the connection. For best results follow the IPC guidelines for cutting traces:</p> <ul> <li>Cutout at least 0.063 mm (0.005 in).</li> <li>Remove all loose material to clean up the cut area.</li> <li>Seal the cut with an approved epoxy.</li> </ul> <p>Reapply solder to reclose the connection.</p> <h3>Normally closed solder jumper</h3> <p>This jumper has an aperture in the stencil to allow solder paste to bridge the split in the wire so it's normally closed (NC). Wick off the solder to open the connection. Reapply solder to reclose the connection.</p> <h3>Normally open jumper</h3> <p>This jumper has three pads in close proximity to each other. Apply solder to close the connection(s).</p> <h3>Normally closed trace jumper (1 of 2 connections)</h3> <p>This jumper has a trace between two pads so it's normally closed (NC). The other connection is normally open (NO). Use a razor knife to open the connection. For best results follow the IPC guidelines for cutting traces:</p> <ul> <li>Cutout at least 0.063 mm (0.005 in).</li> <li>Remove all loose material to clean up the cut area.</li> <li>Seal the cut with an approved epoxy.</li> </ul> <p>Reapply solder to reclose the connection, or to close the NO connection.</p> <h3>Normally closed trace jumper (2 of 2 connections)</h3> <p>This jumper has a trace between all three pads so they are normally closed (NC). Use a razor knife to open the connection(s). For best results follow the IPC guidelines for cutting traces:</p> <ul> <li>Cutout at least 0.063 mm (0.005 in).</li> <li>Remove all loose material to clean up the cut area.</li> <li>Seal the cut with an approved epoxy.</li> </ul> <p>Reapply solder to reclose the connection(s).</p> <h3>Normally closed solder jumper (2 of 2 connections)</h3> <p>This jumper has an aperture in the stencil to allow solder paste to bridge both connections. Both connections are normally closed (NC). Wick off the solder to open the connection(s). Reapply solder to reclose the connection(s).</p> <h3>Normally closed solder jumper (1 of 2 connections)</h3> <p>This jumper has an aperture in the stencil to allow solder paste to bridge one of the two connections. One connection is normally closed (NC), while the other is normally open (NO). Wick off the solder to open the connection. Reapply solder to reclose the connection. Apply solder to the other side instead to change the current path.</p>
