Termination and Assembly

Assembly and Part Marking

Some of our other capabilities include:

• Pad printing to produce high quality ink markings on flat and curved surfaces. You can choose from epoxy ink per A-A-56032 or the material of your choice
• Hand ink stamping
• Dot peen or stamp markings on metal items

Wire Stripping and Cutting

Nortech uses high quality automated and manual equipment to produce nick and scrape-free wire strips and cuts.

• Schleuniger automated cut, strip and coil equipment
• Automatic and semi-automatic wire strippers
• Die type hand strippers
• Thermal strippers

Jacket Stripping

Our jacket stripping is performed using semi-automatic equipment. It includes non-round jackets to preclude damage to shields or insulations that may be encountered when using hand tools.

Crimping

High quality crimps are obtained through crimp tool selection and calibration.

• Our operators are trained to IPC-A-620 requirements
• Crimp tools are selected to meet requirements of MIL-DTL-22520 or connector manufacturer’s specifications
• Nortech uses air or hydraulic assisted crimp tools are used where possible
• Termination presses and applicators for strip form contacts are controlled to manufacturer’s specifications including crimp height

Soldering

• All soldering is performed by IPC-A-610 trained personnel
• Soldering to 32 AWG is regularly performed
• We offer dip solder capability for things like ground straps
• Nortech also has torch or high output 1000-Watt iron capability

Shield Termination

Nortech offers multiple ways to attach overall braided shields to backshells.

• All shields are terminated 360 degrees using copper foil tape if necessary to fill gaps in expanded braids.
• Soldering overall shields 360 degrees around backshells provided by Nortech gives you the best in low resistance and high reliability. Using our backshells with solder terminations is lowest cost, low profile and lightweight.
• Termination bands made of stainless steel are a good option when soldering is not desired due to backshell or braid materials such as stainless steel or Kevlar®. Bands in multiple widths are suggested in accordance with SAE AS85049/128.
• Crimp rings are available as custom or catalog items for shield terminations. Crimp rings can be compressed 360 degrees or in a hex pattern.

Torque Assembly

Assembly of backshells, screws and threaded components with or without adhesives is achieved using calibrated torque tools. We use off-the-shelf connector mates and have the capability to manufacture custom solutions for complex assembly operations.

Circuit Boards

The Nortech engineering team incorporates active and passive components and printed circuit assemblies into cable assemblies. These items can be accessible through custom housings and backshells or securely sealed and isolated from shock within moldings.

ESD Control

Any electro-static discharge sensitive items and assemblies are processed in controlled areas with monitoring per industry standards to assure susceptible component reliability.

Harness Boards & Fixtures

Fixtures are used to the maximum extent possible for error proof assembly. Most fixtures are solid modeled, and 3D printed to match exact profiles. Nortech harness boards are designed and manufactured combining 3D printed fixturing into boards to provide precise dimensional control. All fixturing is manufactured in house to reduce lead time and cost.
