Thermally Conductive Insulators

Solutions-Driven Thermal Management Products for Electronic Devices Comprehensive choices for a cleaner and more efficient thermal interface

More than 25 years ago,Bergquist set the standard for elastomericthermal interface materials with the introduction of Sil-Pad.Today, Bergquist is a world leader with a complete family of Sil-Pad materials to meet the critical needs of a rapidly changing electronics industry.Sil-Pad thermally conductive insulators,in their many forms,continueto be a clean and efficient alternative to mica,ceramics or grease for a wide range of electronic applications.Bergquist application specialists work closely with customers to specify the proper Sil-Pad material for each unique thermal management requirement.

Features Benefits Options Applications

The Sil-Pad family encompassesdozens of products,each with its own unique construction,prop- erties and performance.Here are some of the important features offered by the Sil-Pad family:• Proven silicone rubber binders• Fiberglass,dielectric film or polyester film carriers• Special fillers to achieve specificperformance characteristics• Flexible and conformable • Reinforcements to resist cut-through• Variety of thicknesses • Wide range of thermal conductivities and dielectric strengths Choosing Sil-Pad thermal products saves time and money while maxi- mizing an assembly’s performance and reliability.Specifically:• Excellent thermal performance• Eliminates the mess of grease • More durable than mica • Less costly than ceramic • Resistant to electrical shorting • Easier and cleaner to apply • Under time and pressure,thermal resistance will decrease• Better performance for today’shigh-heat compacted assemblies• A specific interfacial performancethat matches the need• Efficient “total applied cost”thatcompares favorably with other alternatives Some Sil-Pad products have special features for particular applications. Options include:• Available with or withoutadhesive• Some configurations are wellsuited for automated dispensing and/or placement• Aluminum foil or imbeddedgraphite construction for applications not requiring electrical insulation• Copper shield layer • Polyester binder material for silicone-sensitive applications• Polyimide film carrier forincreased voltage breakdown• Materials with reduced moisturesensitivity• Available in rolls,sheets,tubes and custom die-cut parts• Custom thicknesses and constructionsWe produce thousands of specials.Tooling charges vary depending on the complexity of the part. The large family of Sil-Pad thermally conductive insulators is extremely versatile.In today’s marketplace,Sil-Pads are used in virtually every component of the electronics industry,including:• Interface between a power transistor,CPU or other heat- generating component and a heat sink or rail• Isolate electrical componentsand power sources from heat sink and/or mounting bracket• Interface for discrete semicon-ductors requiring low-pressure spring-clamp mounting• Consumer electronics • Automotive systems • Telecommunications • Aerospace • Military • Medical devices • Industrial controls
