Application: Dielectric shielding of DC to DC filters for both active and passive filtering to achieve greater than 40 dB of noise attenuation from 60 Hz to 1 Mhz.
DuPontTM CIRLEX® laminated to aluminum on two sides was used in this application to provide a three-fold solution for the customer:
The customer was able to replace a heavier 15mil aluminum material with the custom laminate that not only reduced the units overall weight considerably but also eliminated the need for a secondary coating process.
The product’s overall performance increased greatly.
The cost of the product was reduced.
Portable X-ray Unit
Application: Dielectric shielding for Remote, Compact Radiographic and Fluoroscopic System designed for use in space constrained offices and field diagnostics that is capable of meeting a wide variety of digital record and fluoroscopy exam needs.
CIRLEX® is used as a main dielectric shielding component in the new units to allow for highly dense and powerful components to be in close vicinity. The excellent thermal, dielectric and dimensional properties of CIRLEX® make this possible.
All-Polyimide Flexible Heater
Application: All-Polyimide heaters are being sought for their high performance in demanding applications. Their main qualities are:
Low Weight and High Performance; Very Thin & Very Efficient
Very Cost Competitive
Extremely High Constant Operating Temperature
Flexible Board to Board Connector
100% all polyimide construction; absolutely no adhesives
Can have multiple layers of polyimide and metallization
Can operate at temperatures from -269°C to +250°C
All materials have same dielectric constant / impedance matched
Flex-to-Board Connectors, BGA & LGA Sockets
Solder Pad Stencils
Flex Circuit Stiffeners
Used in many applications where the durability and strength of polyimide are required
Can be used with many adhesive types including PSA’s and Thermosets
Used in applications where extreme conditions, such as temperature and corrosive atmosphere, are present.
Can be scored and folded in slight most cases to fit into non-flat applications
Has all the electrical properties expected in a polyimide material
Fiber Optic Laser Guides
CIRLEX® is easily machined to make complex deigns that can be used in many gasket and seal applications.
CIRLEX® presently used in mechanical seal applications where durability in extreme conditions is required.
Stand-offs and Spacers
CIRLEX® is currently used as a high temperature spacer in military engine systems. Both thermal and mechanical strength is required in this application.
Fine Line and Rigid Flex Circuits
CIRLES® can be used in conjunction with other all polyimide materials to make variable thickness, rigid-flex assemblies. Current applications in micro-electronics and high frequency communications.
High Temperature, Flexible and Rigid-Flex Heaters
Can be used to make very reliable flexible heaters. All polyimide systems are by construction UL®-94V0 capable.
