Rigid / Flexible Laminated Busbar Applications
[Close]
By laminating ALSET™ metal–resin film composites into a metal / resin / metal / resin / metal… busbar structure, the number of conductive surface layers increases, significantly reducing skin effect. Under high frequency AC conditions, this lets the same cross sectional area carry higher currents.
Our flexible laminated busbars also eliminate cracking caused by automotive vibration.
In addition to single metal constructions, we accommodate dissimilar metal combinations — such as copper and aluminum — for optimized performance.
Standalone Applications of ALSET™
[Close]
ALSET™ metal–resin film laminate is produced without adhesives, eliminating concerns over adhesive cohesive failure during processing and enabling metal‐like workability.
Features
- Eliminates the separate insulation‐film lamination step
- Eliminates metal coating/painting processes
- Enables miniaturization and space savings (reduced creepage distance)
- Delivers both electrical insulation and heat dissipation (versus pure resin)
Typical Applications
Capacitor housings; battery and electronic component cases; and other precision enclosures.
Thermal Welding Applications
[Close]
By choosing appropriate pellets and a heat weldable film for the resin layer of ALSET™, you can thermally weld metal and resin together using only the heat of your injection molding tool. No pretreatment of either the metal or the resin is needed, streamlining your process.
Features
- Composite metal and resin using heat alone
- Achieve lightweight metal components
- Impart electromagnetic shielding properties to the resin
- Enhance the resin’s heat dissipation performance
Typical Applications
Electromagnetic shielding components (e.g., inverter housings)
