Hakko FR-872-03 Infrared PCB Preheater – Precision Heat for PCB Assembly & Soldering

The Hakko FR-872-03 IR PCB Preheater is a low-profile, bench-top system designed to efficiently elevate the temperature of printed circuit board (PCB) assemblies. By utilizing advanced infrared (IR) heating technology, the FR-872 ensures precise, uniform heat distribution across the board, making it ideal for medium to high-mass assemblies that tend to “heat-sink” much of the energy from traditional soldering irons or handheld hot air tools. This preheater is particularly effective when working with Pb-free soldering and is essential for SMD soldering, PCB assembly, and component reflow, as it helps avoid thermal shock and reduces the risk of damage to sensitive components. Whether you’re working with multi-layer PCBs, fine-pitch components, or performing electronics repairs, the FR-872 delivers superior, controlled heat for better soldering and desoldering results, ensuring optimal performance and high-quality outcomes every time.

Features & Benefits

• 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)

The HAKKO FR-872 4-Bank IR Preheater provides a fast and efficient method of preheating large and small PCB assemblies while still on the workbench but in a very controlled fashion. This preheater uses a new high efficiency carbon filament IR heating lamp that nearly eliminates the visible spectrum while maintaining a very high output in the infrared spectrum with minimal shadowing, allowing for a very even preheating of the PCB.

It has the same operation as the smaller HAKKO FR-870 but has 4 switchable zones of preheating compared to just 2, and both manual and automatic modes of operation using either a thermocouple for closed-loop feedback of the PCB heating, or using power settings of the heaters.

Its ramp control feature allows you to control the ramp rate of the PCB when using either of the thermocouple modes of temperature control. The feature allows you to select ramp rates of 1, 2, or 3 degrees Celsius per second. Settings of the preheater can be locked out using a password to prevent inadvertent changes that could affect the process.

As with the HAKKO FR-870, the new HAKKO FR-872 allows for automatic operation following a 3-heating zone profile that can be programmed into the system. A total of 10 profiles can be stored for each mode of operation, for a total of 20 possible profiles. The HAKKO FR-872 also integrates for start/stop operation to work in conjunction with the hot air rework profiles programmable into the HAKKO FM-206 or HAKKO FR-803B (integration requires an optional connection cable that is not included).
