FR-872 IR PCBoard Preheater

List Price:

The Hakko FR-872 Infrared 4-Bank sleek low profile, bench top PC Board Preheater is especially useful on medium to high-mass board assemblies.


The FR-872 is a low profile, bench-top PCBoard preheater designed to elevate the temperature of printed circuit board assemblies so that components on them can be soldered and desoldered more easily, and with improved results. This is particularly useful on medium to high-mass board assemblies, which can “heat-sink” a significant amount of energy being supplied by a soldering iron tip, or handheld hot air tool. The FR-872 is particularly useful when soldering Pb-Free assemblies.

• High efficiency carbon filament IR heating lamps

• 4 independent switchable heat zones

• 8.8 x 10.5 in (224 x 266 mm) effective heating area

• Manual or Auto operation modes

• Preheat controlled by power percentage or thermocouple for closed-loop feedback of the PCB heating

• Ramp Control that controls the ramp rate of the PCB when using either of the thermocouple modes of temperature control

• Soft EPO to protect assemblies

• Automatic operation following a 3-heating zone profile that can be programmed into the system (with up to 20 possible profiles)

• Faster than ceramic IR heating

Integration capability with the Hakko FR-803B hot air and FM-206 rework systems with connecting cable (not included)
