Cable Assembly Processing Capabilities

Epec supports a wide variety of custom cable assemblies that range in technology and complexity from low voltage hook up wires to overmolded breakout assemblies, as well as RG316 coaxial cable assemblies. Whether it is taking an existing industry standard like USB and modifying it, or if it’s a completely new design, our customized cable assemblies provide solutions for all market sectors.

Epec services our customers and helps them achieve their goals through an integrated system of services that will foster a strong and collaborative relationship. We use the highest quality materials, components, and workmanship to design, develop, and manufacture cable assemblies. Built using ISO approved manufacturing processes, our automated wire preparation and assembly systems empower us to supply both your prototype runs and full rate production requirements in a timely manner.

In addition, each new cable design undergoes a complete design for manufacturability review offering opportunities to reduce supply chain risk, improve reliability, or save money. Upon program launch, an integrated product team that consists of customer service, manufacturing, engineering, logistics, and quality will verify that all specifications and program objectives are addressed keeping you the customer informed and up to date.

Epec follows IPC/WHMA-A-620 for all cable assembly, test and inspection practices for all applicable design applications.

Consider a wire to board connector for a quick solution to terminate your cable to a PCBA. See our blog post on Using Wire-To-Board PCB-Mounted Connectors In Your Cable Assembly for more information.

Wire Preparation and Automation

  • Hard wired
  • Flying leads with variable lengths
  • Tinned
  • Stripped and tinned
  • Cut leads
  • Precise cut lengths
  • Strip and tin tolerances of +/- 1mm or better
  • Ultrasonic weld preparation
  • Jacket scoring
  • Heat shrink jacketing
  • Tie and lacing
  • Custom wrapped tapes and foils
  • Conduit
  • Extruded tubing

As complexity increases on wire harnesses, some of the benefits of automation can be impacted. Where possible, decreasing the complexity of your cable may have exponential cost and lead time benefits through automation. See our blog pots titled Why Complex Wire Harnesses Cannot Be Fully Automated for more information.

Ruggedization and Customization

  • Molded members
  • Injection molded components
  • Mating housings
  • Overmolded strain relief
  • Overmolded PCBA assemblies
  • Customized RTV potting
  • Epoxy encapsulation and potting
  • Sleeving and wraps
  • Nylon braiding
  • Shielded and conductive overbraids
  • Barcode
  • Four color ink stamping
  • Circuit Identification
  • Heat shrink labels

If you are considering a custom overmolded design, Managing The Development Of Your Overmolded Cable webinar covers several design tips to reduce risk and cost of your project.


  • Braided wire
  • Overbraiding
  • EMI/RFI shielding
  • Polyester/aluminum foil
  • Polyester/aluminum foil and braid spiral serve wire
  • Foil tapes and wraps
  • Copper tape with adhesive
  • Mil-Spec certified and tested

Since shielding can add cost, weight, or complexity to your cable, and not all shielding is the same, it’s best to review options before moving forward. Read more in our blog post on an overview of cable shielding options for your project.

Adding Components and Sub-Assemblies to Your Wire Harness

  • HDMI/Display Port/Mini Display Port
  • LEDs and other lighting options
  • Fan assemblies
  • Battery terminals
  • PCBAs
  • PCBA housings and enclosures
  • Normally open switches
  • Normally closed switches
  • Grommets and elastomeric boots
  • Embedded systems and microcontrollers
  • Custom machined members
  • Sheet metal and formed members

It is easy to aim for the stars and try to build the perfect solution, especially on your first shot. But sometimes there are simple steps that can be taken to dramatically ease the burden on Engineers. Using an existing and proven design with slight customization can be the difference in your project.

Material Additives

  • Rodent resistant
  • Anti-microbial
  • Anti-fungal compounds
  • Improved hydrophobicity

Adding rodent repellents to your custom cable extrusion helps address a very unique requirement to mitigate the risk damage and open circuits from pests.
