Case Study: Detecting Degraded Circuit Card Assembly (CCA) Components
PSI Repair Services detects stressed CCA components that were overlooked by a major prime contractor’s in-house test system
| Challenge: | A major prime contractor sent PSI a circuit card assembly (CCA) for repair that had already passed its own in-house test inspection. To the customer's surprise, PSI discovered 8 stressed microchips and one hard-failure microchip. If they were not replaced, MTBF would decrease and maintenance costs would increase, ultimately jeopardizing critical missions. |
| Solution: | PSI’s state-of-the-art equipment proved that the prime contractor’s in-house system test did not detect components that were degraded by stress/usage. |
| Result: | PSI made the repairs, which saved the contractor crucial time and money in future repairs. |
