HomeSplice crimping
SPLICE CONNECTION - FROM WIRES AND PCB TO DIODES AND COILS
Splice is a solderless crimp connection formed by crimping a metal clip onto the ends of the components.

Unlike standard terminals, splice connection is applicable to any electrical components of various dimensions and materials: wire, PCB, coil, capacitor, sensor, diode, lead frame, textile, etc. In contrast to welding and soldering, it is vibration resistant and its quality can be evaluated both within and after production.

Customization and reliability of splice solution is further enhanced, since our R&D department defines optimal connection, tooling and splice band parameters in the beginning of the project.

Splice connections are widely used by automotive components suppliers of VW, BMW, PSA, Renault, etc.

WHY DO YOU NEED IT?
SPLICE ADVANTAGES
Unlike soldering, splice technology ensures reproducible quality of a connection possible to control during production process and after it.
  • Reproducible quality
    Reproducible quality

    Splicing as a mechanical process allows getting reproducible high quality. With the same tooling and splice band the quality of a product stays the same from cycle to cycle.

  • Adaptable to product
    Adaptable to product

    Tooling is designed individually for each product so that the splice fits perfectly the components and form reliable connection.

  • Gastight
    Gastight

    The deformation of the components and the splice during the splicing process guarantees gastight connection.

  • Low electrical resistance
    Low electrical resistance

    Connection and tooling engineering guarantees stable low electrical resistance preventing loose strands, misaligned connection and other defects.

  • Deformation and vibrations<br>resistance
    Deformation and vibrations
    resistance

    Splice crimping doesn’t involve heating unlike soldering, thus it keeps components out of burning or melting risks and guarantees good behavior under deformation and vibrations.

  • Compact
    Compact

    Splice allows to make compact and constant size connection with minimum dimensions such as 0.46*0.24 mm cross-section connection for an artificial cardiac pacemaker. Space saving feature is ideal for sensors, bulbs, heating elements, etc.

  • Universal
    Universal

    Splice connection can be performed with various types of components (PCBs, wires, coils, sensors, plastic connectors, filament, etc.), materials (fiber, Teflon, chrome, steel, etc.) and size.

  • Quality control

    Splice allows to make compact and constant size connection with minimum dimensions such as 0.46*0.24 mm cross-section connection for an artificial cardiac pacemaker. Space saving feature is ideal for sensors, bulbs, heating elements, etc.

  • Easy to go
    Easy to go

    Thanks to automation it’s possible to make up to 2000 splices per hour without any experience in splicing.

  • Cost-efficient
    Cost-efficient

    Splice spare parts are cheaper than ones for welding and soldering and it need to be changed rarely: each 300 000 – 3 000 000 assemblies depending on spares and components type.
