BIRNS offers value-added subcontract services, performed in accordance with your specifications/procedures, to MIL-SPEC procedures, or to our own, as you instruct. We encourage customer visits and audits at any stage of the work. Please contact us with your requirements.

Electrical Termination & Assembly

 

All of our electrical technicians are Certified IPC Specialists per J-STD-001, and are skilled at electrical termination and assembly of connectors, cable assemblies, and electrical devices. We terminate connectors made by BIRNS or others; we also make cable assemblies and wire harnesses.

 
As an example: certain Detachments of the US Navy have BIRNS electrically terminate and overmold various models of hydrophone transducers for use on their large ROV's.

Mechanical Termination & Assembly

 

We perform mechanical termination of load-bearing cables with central or coaxial stress members of Aramid fiber or steel. For electromechanical cable assemblies, we perform this termination such that no load is transmitted to electrical conductors even under worst-case scenarios.

As an example: BIRNS designed and terminated a 186-conductor waterproof electromechanical cable assembly to withstand 3,000 pounds of load in any direction - to withstand the high radiation fields inside Chernobyl!


Molding & Overmolding

 

 
We perform in-house molding of epoxy, silicone, polyurethane, polychloroprene and other materials, and design our own mold tooling; we can produce items designed for your exact needs, or modify items as you request. We regularly overmold terminated connectors (made by BIRNS and by others) to cable per customer requests, and repair and splice cable assemblies of various types.


Testing

 

We perform electrical testing per MIL-STD-1344 (to 5 kV), hydrostatic pressure testing per MIL-STD-202 (to 20,000 PSI), and various mechanical pull tests and tests per UL requirements.

As an example: BIRNS testing and QA capabilities are frequently utilized to procure high-pressure glass domes and to qualify them by full-pressure hydrostatic and hydrodynamic testing in accordance with military specifications.


Quality Assurance

 

Our QA system conforms to the requirements of ANSI/ASME NQA-2, "QA Requirements for Nuclear Facility Applications", and we are presently modifying our system to obtain ISO 9001 qualification. We welcome and encourage customer visits and audits at any stage of a job.

As an example: 80% of USA nuclear power plants use BIRNS products inside primary nuclear containment. The Nuclear industry has demanding quality requirements, which BIRNS is accustomed to meeting on a daily basis.
