Highlight Description:

Since 1967, PSI Repair Services, Inc. (PSI) has become a trusted repair source for public and private organizations that rely on electronic, mechanical and electro-mechanical equipment. PSI’s staff includes highly skilled technicians, mechanics and engineers. PSI serves a variety of markets: Aerospace, Automotive, Industrial, Military, Semiconductor, Solar, Transit and Wind. One benefit of our extensive, multi-market experience is exposure to many types of technologies. This background provides PSI technicians with unique insight into many types of devices and controls systems.

PSI provides three main categories of repair.

  • Farebox Bill Transports
  • Proportional Valves
  • Servo Motors


When a customer’s part arrives at our facility, it is logged into our ERP system and assigned a unique identification number. The number tracks the flow of the part, through our repair process. This traceability can be utilized to perform failure analysis, either at the request of our customer, or when we see a significant volume of common failures for a device.

PSI has a variety of specialized equipment to support the repair and rework of a wide range of technologies and products. Vision assisted hot air reflow systems and infrared ovens are some of the state-of-the-art tools we use to remove and install surface mount parts on circuit cards. Other specialized equipment and software includes in-circuit Pinpoint stations, automated test equipment (ATE), Joint Test Action Group (JTAG), Labview, PXI chassis and computer-aided design (CAD).

PSI’s ISO 9001:2015 certified facility possesses the most advanced equipment in the market today for identifying stressed, degraded or hard failed ICs, assuring a “like-new” assembly that often outperforms the original part. PSI technicians are certified in IPC 7111 & 7122 quality standards for rework and repair acceptability of electronic assemblies, and proper soldering techniques.

PSI’s success is largely due to the wide variety of test processes we have developed. In addition, PSI constantly invests in new processes and test tools to stay ahead of the curve, particularly for complex digital circuits.


Descriptions of some of the newer developed techniques includes:

  • In-circuit passive, dynamic digital, functional analog and boundary scan
  • Advanced nodal signatures, functional analog edge connector, dynamic edge connector and cluster digital
  • Variable 3-phase sources, load banks, high voltage DC sources, custom IGBT testers and signal simulators

Custom Engineering Services

PSI engineering provides legacy support services. Our knowledgeable engineers often make design improvements to old components to better fit the customer’s application, resulting in significant cost-savings and performance improvement.

PSI designs replacement components to address obsolescence issues, provides failure analysis leading to corrective engineering, and performs reverse engineering of circuits to generate diagrams, schematics and netlists.


Need to increase the efficiency of your Line Replaceable Units (LRUs)?

PSI provides the option to improve the original design or replicate an entire assembly or subassembly with current, more reliable technology.

PSI’s proprietary test systems detect functional parts which have been stressed or degraded and will fail early, making PSI’s repaired components like new. System test stands cannot detect this type of weakness.

Here are some of the reasons to work with PSI Repair Services:

  • Corrective Engineering
  • Efficiency
  • Engineering Services
  • Experienced work staff
  • Reliability Improvement
  • Repair Savings
  • Root Cause Analysis
  • Sustainment & Obsolescence Management
  • Technical Support
  • Top-Of-The-Line Test Equipment
  • Uptime
