Circuitry and Plated Hole Repair

Circuitry and plated holes can become damaged during processing and rework. One method for repairing damaged circuitry uses the Foil Jumper Method. This method uses pure copper Circuit tracks. The replaced conductors are the same size as the original. This IPC recommended technique is preferable to making circuitry repairs with jumper wires because it more closely duplicates the original fabrication process.

Damaged plated through holes are repaired using eyelets. We have also refined an IPC recommended method for repairing damaged plated holes on multilayer circuit boards that have inner layer connections.

  • This image shows circuitry and conductor damage, including damage to plated holes. During processing it's common for this type of damage to occur.
  • This illustration shows a damaged conductor with a section that has been lifted from the circuit board surface. Preview the remaining slides to learn how we complete this repair.
  • Step 1: We remove the damaged circuits and trim them back to a point where the conductors have a good bond to the circuit board surface. We remove loose material and clean the area.
  • Step 2. We select a Circuit Track to match the width and thickness of each conductor to be replaced. Then lap solder the first end. Learn more.
  • Step 3. The new circuits we use are pure copper and can be formed to match the original conductor path. As needed we carefully bend and shape the Circuit Track.
  • Step 4. We form the final shape and hold the replacement conductor in place with high temperature tape. We then lap solder the ends to the existing conductors as needed.
  • Step 5. We overcoat the new conductor with high-strength, high-temperature epoxy. We often add a color agent to the mixed epoxy to ensure the repair is a cosmetic match.
  • Step 6. To repair plated holes we drill out the damaged holes and select an eyelet that matches the hole dimensions. We use an alternate method on multi-layer circuit boards.
  • Step 7. We insert an eyelet into the drilled hole. If a new circuit is required, the new circuit may extend into the drilled hole and the flange of the eyelet will secure the new circuit in place.
  • Step 8. We use a precision eyelet press to properly set the eyelet and create a flat flange on both the top and bottom sides.
  • This photo shows the repaired conductors and plated holes. This high conformance level repair process follows documented IPC guidelines to ensure the repair is reliable and robust.
Circuitry and Plated Hole Rework
Occasionally errors in the circuit board fabrication process occur, or design changes are needed to upgrade circuit boards. Whatever the reason we can help you overcome the modification requirement. Common applications include adding gold edge contacts, rerouting signal connection, isolating vias and pads or adding an entire component footprint.
