This is a bobbin of our coated copper 36 gauge wire that we use for longer jumpers in the device. For example--a jumper of the 6s backlight circuit from the backlight driver area to the connector area. Be sure to use the iron to burn the insulation so that your jumper can make a solid joint.

For common microjumpers under bga chips like meson and audio ic where insulation is not beneficial, we recommend our Silver Jumper Wire.
