A heat sink is manufactured by forming a fin 2 for dissipating heat by separating a length of material from a substrate 1 while leaving the proximal end attached to the substrate 1. The fins are cut from the substrate by stamping process using the stamping single or progressive die tooling cutting the substrate 1 along dotted line 16. The heat sink is a unitary construction, with the fins 2 being integrally formed with the substrate 1.
