Circuit Board Thermal Interface Pads

These heat-dissipating pads pull heat away from electronic components. They’re often used to fill gaps between two surfaces that require thermal contact. All meet UL 94 V-0 for flame retardance.

An alternative to thermal paste, these soft, flexible pads transfer heat from a source to a heat sink. They compress slightly to make up for surface imperfections and roughness. These pads are conformable with a slightly tacky surface that lightly adheres to both smooth and rough surfaces. Pads meet UL 94 V-0 for flame retardance.
