BERGQUIST® SIL PAD® TSP A3000

BERGQUIST® SIL PAD TSP A3000 uses a different filler package than BERGQUIST® SIL PAD® TSP 3500. This change results in a more compliant BERGQUIST® SIL PAD TSP A3000 material that inherently lowers interfacial resistance losses. This reduction in interfacial resistance results in improved overall thermal performance when measured at lower pressures in standard ASTM D5470 and TO-220 testing

Yes. Henkel evaluates and publishes voltage breakdown, dielectric constant and volume resistivity data per ASTM standards for these materials. Due to differences between ASTM lab testing and actual application performance, for best results, these characteristics should be evaluated within the actual customer system.

The answer is based on the assumption that the primary design intent is to increase thermal performance. If your application uses lower clamping pressures (e.g., 10 to 75 psi), you will find BERGQUIST® SIL PAD TSP A3000 to provide excellent thermal performance. In contrast, if you are designing for higher clamping pressures (e.g., 100 psi or greater), it is likely that you will require the thermal performance characteristics of BERGQUIST® SIL PAD TSP 3500.

Yes. With the environmentally responsible process improvements added with the introduction of BERGQUIST® SIL PAD® TSP A3000 products, the materials are now available in roll form. The original BERGQUIST® SIL PAD TSP 3500 material cannot be produced in continuous roll form.

Each application has specific characteristics (e.g., surface finish, flatness tolerances, high pressure requirements, potential burrs, etc.) that determine which SIL PAD product will optimize thermal performance. Select a minimum of two pads that best fit the application, then conduct testing to determine which material performs the best.

The ISO certification is the adoption of a quality management system that is a strategic decision of the organization. This International Standard specifies requirements for a quality management system where an organization: a) needs to demonstrate its ability to consistently provide product that meets customer and applicable regulatory requirements, and b) aims to enhance customer satisfaction through the effective application of the system, including processes for continual improvement of the system and the assurance of conformity to customer and regulatory requirements.
