BGA Component Site Modification

When your design requires a change or modification at a BGA site, using a standard jumper wire is normally not an option. Jumper wires are simply to large to fit under a BGA component. The ingenious modification procedure employed at Circuit Technology Center uses flat copper ribbon thin enough to fit safely under the BGA component.

For more on this IPC recommended procedure see Jumper Wires, BGA Components.

  • Step 1: We cut the connection to the via using a Precision Drill System.
  • Step 2: We remove the BGA pad and mill a shallow channel into the solder mask surface.
  • Step 3: We bond a new BGA pad in place.
  • Step 4: We solder a copper circuit track to the tail extending from the new BGA pad.
  • Step 5: We Solder a wire to the Circuit Track and overcoat it with epoxy.
