AUTO PIERCING technology for magnet wire: SM Contact starts production of P-type splice band
18/11/2022
Auto piercing by splice crimping is a cost-effective alternative to IDC terminals, soldering and spot welding in magnet wire applications. SM Contact launches production of splice band for piercing of enameled wires - P-type splice band, in addition to the standard one.
Magnet-piercing splice band is leveraged in connecting power/signal and magnet wires (coils) in electric motors, e-mobility (EV charging stations) and household appliances. It enables one-step reliable gas-tight connectivity between standard power wire and insulated magnet wire. Auto piercing technology offers advantages of a low cost and fast cycle time.
Advantages of auto piercing technology:
1 - Repeatability:
stable quality with the mechanical process and control of the splice band shape => stable electrical connection without component damage risk.
2 - Reduced cycle time:
by eliminating soldering and stripping operations (0.3 sec).
3 - Qualified and validated connection supported with data sheet:
all required parameters, such as pull force, compression rate, contact resistance, are reached by computer simulation and laboratory studies using a certain splice band.
Standard process vs. Technology of splice crimping with P-splice band
P-type splice band provides a method of connection of an enameled magnet wire directly to wire or component.
Standard process - soldering and spot welding
Technology with P-type splice band
1. Stripping / burning insulation from the wire ends,
2. Soldering (welding) to wire or component.
1. Splice crimping of an unstripped magnet wire directly to wire or component.
- hard controlled process,
- soldering puts components at risk of melting or burning and makes them breakable,
- it can be difficult to solder near plastic parts.
- saving cycle time,
- saving cost,
- controlled process,
- without heating,
- easily scaled for different production volumes,
- no pre-stripping of insulation.

Advantages of using P-type splice band by SM Contact with SM Crimp equipment:
1 - Zero tooling damage risk:
splice band characteristics are considered for connection qualification and machine settings.
2 - Optimal connection properties:
required parameters specified in the data sheet are reached by using a certain splice band - produced by SM Contact. Third-party splice band may not allow achieving these characteristics.
