Select thickness based on gap (0.2, 0.5, 1.0 mm common) and conductivity based on heat flux. Smartphones often use 0.8–5 W/m·K, high-power modules ≥6 W/m·K.

Yes — most silicone and non-silicone grades are dielectric. Always confirm breakdown voltage specs for your model.

Pads are clean, automatable, and consistent for fixed gaps. Pastes can be thinner and more conductive but are messy and less scalable.

Yes — thickness, hardness, adhesives, and conductivity can be customized. Samples available on request.
