2UUL Insulated Jumper Wire Copper Wire 0.02mm 100m

Ultra-thin Enameled Conductor for Micro Soldering 2UUL

The 2UUL insulated jumper wire copper wire is a precision consumable designed for reconstructing broken traces on printed circuit boards. With a thickness of only 0.02mm, it allows bridging on high-density components without short-circuit risk due to its protective coating. It features a total length of 100m, ideal for workstations with continuous electronic repair volume.

What Distinguishes This Model

The reduced thickness of 0.02mm combined with the insulating layer allows overlapping conductors directly on the board and beneath BGA integrated circuits. The compact 100m spool ensures durability in bench consumption, avoiding frequent interruptions for consumable replenishment.

Usage Tips

To obtain adhesion in soldering, gently scrape or heat with the soldering iron tip the wire extremity to remove the insulating varnish before applying solder. Use surgical precision tweezers and a microscope to position the line accurately over damaged pads.

Frequently Asked Questions

Does the wire cause a short-circuit if it touches other traces?

No, the conductor body has an insulating layer that prevents accidental electrical contact along the path.

Is it necessary to scrape the insulation to solder?

Yes, the ends that will be joined to the solder points must have the insulating varnish removed or thermally stripped to establish electrical contact.
