Laminated busbar quality is determined long before the first electrical test — it is built into the layup, the lamination window and the terminal welding.
| Material | Standard options |
|---|---|
| Conductors | C11000 copper as standard; aluminum available on request |
| Dielectrics | PET, Nomex and epoxy (DLF) films, selected by voltage class and operating temperature |
| Plating | Tin finish for corrosion protection and joint solderability |
Per customer specification and applicable standard.
Measured on sampled parts per lot.
Terminal positions, hole sizes and envelope vs drawing.
Plating coverage, edge sealing and weld quality.
Electrical verification of each conductor path.
Maß- und elektrische Prüfaufzeichnungen werden je Produktionscharge geführt und können der Lieferung auf Anfrage beiliegen.
Bevor Werkzeuge geschnitten werden, führen unsere Ingenieure eine DFM-Prüfung Ihrer Zeichnung durch – Schichtzahl, Strompfade, Anschlussabstände, Kantenabstände und Dielektrikum-Spielräume. Eine knappe Kantenentfernung oder eine zu kleine Schweißzone ist in dieser Phase weit günstiger zu beheben als in der Produktion.
Stack-up validated against voltage class and current.
Cross-sections checked against continuous and peak current.
Pitch and weld zones matched to mating hardware.
Creepage and dielectric clearances verified before tooling.
Our in-house QC process — hipot, insulation resistance, dimensional, visual and continuity checks on every lot — is the internal half of quality. The external half is the standards landscape our customers design to, and it is worth being explicit about which standards apply to power-interconnect parts and how they show up in the drawings we build to.
Component assemblies used in power distribution, including high-current connectors.
Sits alongside UL 1977 on recognized connectorized power-distribution assemblies.
Routine expectation for insulator housings and dielectric systems on shipped parts.
Baseline on shipped product; halogen-free constructions available where the spec calls for it.
Application-level standards: SAE J1772 · EV charging couplersOpen-rack platform specs · in-rack busbar interfaces — these set the current-interruption, arcing and cycle-life tests the interconnect must pass.
We do not hold aerospace or defense qualifications ourselves — and we do not claim to — but customers in those programs routinely flow down their own standards and special-process requirements to the parts we build.
Two technical references explain the physics behind the tests we run:
Qualität entsteht im Aufbau, im Laminierfenster und im Anschlussschweißen – und wird anschließend verifiziert und protokolliert.
