Submitted Photo Senior Airman Nicholas Lane, left, and Senior Airman Christopher Mahlert, right, Air Force Repair Enhancement Program (AFREP) technicians assigned to the 5th Maintenance Squadron, micro solder a circuit board on Minot Air Force Base on April 21. Micro soldering and 3D printing are the two main capabilities that allow AFREP to make efficient and inexpensive repairs to minor defects in flight equipment. AFREP saves the unit millions of dollars every quarter by making minor repairs to pilot keypads, nuclear trailer extender cards and aircraft ground and test equipment.
