Lead (Pb)-free soldering requires temperatures elevated by around 30°C. To avoid problems connected with excessive temperatures from above, rework specialist, Martin, introduced a new underheater. The Hot-Beam-03 is an instant quartz heater that heats the printed circuit board quickly and within allowable limits, to approximately 130°C.
Since simply increasing the soldering iron temperature by 30 to 50°C for lead-free rework is risky, by taking over half of the thermal effort from underneath the PCB, the Hot-Beam-03 enables gentler treatment of the PCBs and components.
The compact unit has an active surface of 10 x 13 mm and a power output of 500 W. Its program-controlled IR underheater uses a self-learning process, maintaining a precisely-defined and constant thermal mass by a fine sensor control.
