Home/Technical Glossary/Pulsed Heat Pulsed Heat Pulsed Heat (as in a pulse heated reflow power supply) refers to the rapid update of the energy output to the thermode based on the temperature feedback loop. This enables the power supply to control the temperature profile of the thermode and thermal transfer to the parts. Pulsed heating allows the thermode to heat and cool quickly.
