Mica Thermofoil Heaters
High watt density and temperature range
Overview
Mica Thermofoil™ heaters consist of an etched foil element
sandwiched between layers of mica. Installed by clamping to
heat sinks, mica heaters provide the ultimate temperature
and wattage capability for fast warmup.
• Broad temperature range of -150º to 600°C provides faster
processing and cycle times for greater production output
• High watt density capability to 110 W/in² (17 W/cm²)
provides faster processing times than conventional mica
strip heaters
• Custom profiled heat density and mechanical clamping
offers uniform heat sink temperature which can improve
processing yields
• UL certification is available which can save time and
money for end-use UL device recognition
• Can be factory formed to curves
• Heaters are suitable for vacuum use after initial burn-in
(see next page)
Typical applications
• Semiconductor processing
• Packaging, strapping, and sealing equipment
• DNA thermocycling
• Food service appliances
• Plastics and rubber molding supplemental heat
Custom options
• Custom shapes and sizes to 22” × 46” (560 × 1168 mm)
• Custom resistance options up to 25 W/in² (3.9 W/cm²)
• Factory forming techniques offer three dimensional
packaging capabilities
• Integral temperature sensors
