DC to DC Filter
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.

Cirlex® laminated to aluminum on two sides was used in this application to provide a three-fold solution for the customer:

1. 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.
2. The product’s overall performance increased greatly.
3. 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.

Flexible All-Polyimide Heater Application: All-Polyimide heaters are being sought for their high performance in demanding applications. Their main qualities are: All-Polyimide Construction Low Weight and High Performance; Very Thin & Very Efficient Excellent Durability Very Cost Competitive Extremely High Constant Operating Temperature

Flexible Board to Board Connector
Application:

• Rigid-flex design
• 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 Cirlex® is widely used in high performance Flex-to-Board Connectors. This material is used when high reliability and performance in molding operations is required to manufacture high density connector assemblies. BGA and LGA sockets also require very stabile material that can withstand high temperature molding and assembly operations. Cirlex® is the only material found to do this and be cost effective.

Solder Pad Stencils

• Stencils can be pure polyimide or a laminate of polyimide and metal foil. i.e polyimide + Stainless Steel
• Polyimide and polyimide laminate stencils are more durable and resist bending and tearing better than mesh 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

Electrical Insulators

• 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

Gaskets and Seals

• 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.
  Wear Pads

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

• Cirlex® 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.
