Thermal tape (thermally conductive tape) is a pressure-sensitive adhesive tape filled with ceramic particles that carries heat away from electronic components while bonding them to a heat sink or spreader, replacing mechanical fasteners, clips and liquid adhesives in one step. <\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

It is the practical choice when you need a thermal interface material that also holds the assembly together: 3M's thermally conductive tapes deliver conductivity from 0.6 to 1.5 W\/m\u00b7K in thicknesses from 0.1 mm to 0.5 mm, with dielectric strength up to 26 kV\/mm.<\/p>\n\n\n\n

<\/p>\n\n\n\n

This guide compares the 3M\u2122 thermally conductive tape range spec by spec, explains which numbers actually matter when you select one, and shows how RGH supplies these materials as ready-to-place die-cut<\/a> thermal pads, including the converting decisions that matter with a material this delicate.<\/p>\n\n\n\n

Thermal tape vs. thermal paste vs. thermal pads<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

All three are thermal interface materials (TIMs): they fill the microscopic air gaps between a hot component and its cooling surface. Air is a poor conductor at roughly 0.03 W\/m\u00b7K, so even a modest TIM transforms heat transfer. The right choice depends on whether you also need the joint to carry mechanical load:<\/p>\n\n\n <\/div>\n\n<\/div>\n\n\n\n\n\n
