With the exception of the conventional apparatuses, than they are based on the stored energy, the systems series MFR use the technology Smart Heat for to have distributed in automatic rifle all the power where, when and how much serves. Besides not to never demand the calibration, these systems incorporate two independent doors and also the exclusive device of car-extinction when not in use. MFR-SDX is born like saldatore and dissaldatore, but its configuration can be widened adding the thermal clamp for the rework of Smd. The reason for which we do not call it simply saldatore or dissaldatore, but arranges of rework, has had to the fact that already with the solo I draft and the nourished series of sagomate tips, every system MFR concurs to knit the little one chip, thus like removing, dissaldare and river-to knit every type of integrated circuit, until arriving to the SOIC, PLCC and QFP also of great dimensions.
