The PCT-100 bottom heater focuses hot air on the area where the component to be reworked is located on the circuit board. It increases speed and efficiency in thermally demanding applications, including lead-free processes. Suitable for both SMT and through-hole assembly, it preheats the circuit board using hot air, thereby improving solder joints, process control, and productivity. The PCT-100 bottom heater increases the heat volume without raising the temperature values too high. This allows assembly processes to consistently occur at an appropriate peak temperature without damaging the circuit board.
