Our Typical Repair/Refurbishment Process

Paragon performs a detailed receipt inspection on customer-supplied material.

We test, troubleshoot, and identify replacement components suitable for the application. Replacement components are evaluated and inspected upon receipt.

Repairs are performed by certified IPC 7711/7721 specialists. The repairs are independently inspected to IPC 610, and customer specifications by certified IPC 610 Inspectors.

The customer-supplied item then undergoes a post repair test, burn-in, and final acceptance test.

Paragon develops innovative solutions for the nuclear industry that are safer, more reliable, and more cost-efficient.
