Quality Policy

NAI is committed to pleasing our customers by manufacturing products that comply with regulatory, industry & customer requirements to be delivered on-time, every time using a continuous improvement approach.

Strict Quality Processes

At NAI, we integrate the principles and tools of Lean Manufacturing in our everyday operations. Statistical Process Control methods are employed throughout our planning, sourcing, incoming materials, manufacturing and outgoing processes to reduce variation in our end products.

 

Quality is the focus of relentless pursuit at NAI.

A Sampling of NAI QC Processes

  • Out of Box Audit (OBA) for incoming material
  • Product Quality Planning Project Status Report
  • Advanced Product Quality Planning (APQP) process, as used in the auto industry
  • Traceability
  • Fibers kept clean throughout manufacturing
  • All harnesses tested on working boards
  • Critical to Quality (CTQ) processes for testing additional production parameters, often defined by the customer
  • Calibration technicians continuously monitor and maintain NAI measurement equipment
  • Regular Kaizen events
  • Customers have access to all QC data associated with their projects

NAI Certifications

NAI maintains a rigorous internal quality management system in compliance with the strict regulations of the regulated markets we serve.

 

NAI maintains the following certifications:

  • ISO 9001:2015 – for overall quality
  • ISO 13485: 2016 – for medical cable assembly quality
  • TL9000-H 6.0/5.0 and 5.5 – for telecom product quality
  • AS9100D – for aerospace product quality
  • 2011 C-TPAT
  • UL and C(UL) certifications

In addition, NAI has often been certified for many other specific quality or product protocols as required by certain industries and customers, such as UL, Intertek and NADCAP. Let us know your project requirements, and we will obtain the necessary certifications.

Fiber Optics: Inline Quality Control

All assemblies are 100% inspected. State of the art equipment is employed for polishing, loss tests, laser cleavers, fiber fusion (splicing), cross section, thermo-chamber and immersion testing. All fiber optic cable assemblies are continuously tested throughout manufacturing for:

 

  • Insertion Loss/Return Loss
  • Attenuation
  • Geometry, including concentricity and light continuity
  • End face inspection after polishing

 

Air cleaning equipment removes contaminants at various stages of manufacturing.

 

If any part fails testing, the test unit automatically locks up. The operator is then required to have the Quality Dept. release the part from the test unit and fix the problem before continuing with assembly production.

Copper: Inline Quality Control

NAI produces copper cable assemblies and harnesses using leading edge test procedures and equipment to ensure optimal performance. All assemblies are 100% inspected. Electrical tests include continuity, high voltage (HiPot) and capacity. Some of the other tests we perform include:

 

  • Subassy electrical test
  • Manufacturing visual inspection
  • QA inspection
  • Plug blade height
  • Tensile test
  • Pressure test
  • Texture test
  • Fluke test (Insertion Loss/Return Loss)

Measuring Performance

  • Six Sigma philosophy with Black Belt teams overseeing production thru a Four Block/Pack KPI daily measurement
  • Performance measurement is being monitored and controlled in each organizational layer, from DL thru Top Management
  • Preventive and corrective activities are activated with constant KPI revision on each level; the longest cycle is one week.

Cross Training

  • NAI utilizes the Train Within Industry (TWI) approach for training all labor in manufacturing sites
  • We build a flexible structure by following the 3×3 principle. Every operator must excel in 3 different process operations and each process operation must be operated by 3 different operators.
  • Immediate improvement on skills is initiated based on ILU workshop front line management
  • Long-term improvement is evaluated by assessing skill points
