Read MoreSPLICE 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.

SPLICING
1. Components positioningComponents are located in splice crimping area of a machine in a proper order.
2. Splice band cuttingMetal clip of a required length is cut from the reel-wound splice band and moved down to the components.
3. Splicing the componentsU-shape splice is compressed tightly around the components’ ends.

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
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
Tooling is designed individually for each product so that the splice fits perfectly the components and form reliable connection.
Gastight
The deformation of the components and the splice during the splicing process guarantees gastight connection.
Low electrical resistance
Connection and tooling engineering guarantees stable low electrical resistance preventing loose strands, misaligned connection and other defects.
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
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
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 quality is easy to be controlled unlike soldering with a help of inline systems (Crimp Force Monitor, camera position and color control, Poka Yoke, etc.) or standalone laboratory equipment (cross section, pull force, crimp height measurement, etc.).
Easy to go
Thanks to automation it’s possible to make up to 2000 splices per hour without any experience in splicing.
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.
