    Temperature and humidity control, ESD protection, and specialized fire control equipment are just a few of the few of the requirements of a company if they want to work with companies like Sanyo and Panasonic.

  • IPC Certified Soldering

    IPC Certified Soldering
    All of our soldering technicians are IPC trained and certified so that we can assure the highest level of quality on our product.

  • Spot Welding Process

    Spot Welding Process
    The most attractive feature of newest spot welding equipment is that the energy delivered to the spot can be controlled to produce reliable welds.

  • Heat Shrink Oven

    Heat Shrink Oven
    The Heat Shrink Oven shrinks tubing in a fraction of the time required by a heat gun as it reaches the optimum operating temperature to quickly and uniformly shrink tubing.

  • Soldering Stations

    Soldering Stations
    Our dedicated and ESD protected soldering stations allow us to manage multiple assemblies during our 24/7 operation.

  • Wire Cutting and Stripping

    Wire Cutting and Stripping
    To optimize production rate, repeatability and accuracy of the wire length, Epec has continued to invest in equipment to ensure quality.

  • Ultrasonic Welding Equipment

    Ultrasonic Welding Equipment
    Each custom battery pack that requires a plastic enclosure can be sealed by adhesives, mechanical screws or the latest in ultrasonic technology.

  • Pull Test Equipment

    Pull Test Equipment
    Used to measure the strengths of the tab welds on the cells to ensure that the connections last while in use.

  • Final Assembly

    Final Assembly
    At this step all of the pieces are put together in the final assembly. These can include printed circuit boards, thermistors, membrane switches and many other products depending upon the features of the battery pack.

  • Custom Testing Equipment and Procedures

    Custom Testing Equipment and Procedures
    Battery testing is done on battery packs at both the prototype and production levels. Our in-house capabilities allow us the ability for programming and testing that may be required at the customer level.
