Question: Can we bridge two adjacent pins on an IC using bare wire across those two pins? What specification do we reference for the acceptance of the rework performed?
Answer: The answer is yes, provided it is requested and documented by engineering. Make sure the wire does not violate minimum space requirements between the ends of the wire and the adjacent leads. Verify the wire solders properly to the leads, i.e., good wetting to both wire and component leads.
If the wire is a small enough gauge, then it can be wrapped around the component lead and that would also be acceptable.
See section 7.5, Jumper wires in IPC-A-610.
