Value-added assemblies and complete thermal solutions.
Overview
For best heater performance and reduced installation costs,
consider Minco’s capabilities in mounting heaters to make
complete thermal subassemblies. You can furnish the heat
sinks or we can fabricate them to your specifications. Either
way, you get a guaranteed bond, superior reliability, and the
benefits of Minco’s experience with advanced adhesives and
lamination equipment. In many cases we can affix the heater
to the mating part in the same step used to bond its layers
together. That saves money over a two-step process.
Vulcanized silicone rubber assemblies
Minco’s proprietary vulcanization process uses no adhesive
to bond heaters to mating parts. Eliminating the adhesive
facilitates heat transfer, resulting in higher
allowable watt densities and longer life.
Laminated polyimide heaters
Polyimide (e.g. Kapton™) heaters can be mounted to flat or
curved heat sinks using an acrylic adhesive and our specialized
lamination equipment. The thin, uniform bond layer provides
excellent heat transfer. Watt densities to 50 watts/in²
(7.8 watts/cm²) are possible.
Clamped mica heaters
Mica heaters must be secured between rigid plates to prevent
separation of layers. Minco can provide many styles of mica
heater assemblies: bolted, riveted or welded, flat or curved.
Factory mounted All-Polyimide (AP) heaters
Factory bonded AP heaters eliminate clamping and provide
optimum heat transfer to the heat sink. The excellent chemical
resistance and low outgassing
of AP heaters, together with
Minco’s precise machining
capabilities, are the perfect
solution for chuck heaters in
semiconductor processing
equipment.
