Jump Wire
  • We can see that several pads have come off the board. Among these missing pads, S7, S8 S11 and S12 are important signal pins. We need to treat them by jumping wires.

  • The rests are ground pins and test pins. We can just leave them alone.

  • Apply paste flux to the four missing signal pins. Heat with the pointed-tip Soldering Iron. And solder 0.02mm Enameled Copper Wire to the four missing pads respectively. Once done, cut off the excess wire with Sculpture Knife. Then loop the wire around the missing pad.

  • Apply some UV Curable Solder Mask afterwards.

  • Remember to scrape off excess UV Curable Solder Mask. Make sure the soldered wire is exposed.
