ZM-R7220A Infrared SMD Rework Station – Intelligent technology for precise rework
The ZM-R7220A infrared SMD rework station is a modern and intelligent infrared soldering station with real-time temperature monitoring, an optical alignment system, and a fast heating and cooling function. Developed by Zhuomao, a leading manufacturer of rework systems, it offers maximum precision and reliability when working with sensitive BGA and SMD components. It is also attractively priced without compromising on quality or performance.
Real-time temperature monitoring for maximum control
The ZM-R7220A infrared SMD rework station monitors the temperature in real time. Temperature curves are automatically analyzed and displayed via the integrated 7-inch HD touchscreen. This provides the user with precise feedback throughout the soldering process and allows adjustments to be made immediately.
Optical HD alignment system for precise work
The integrated 2-megapixel CCD imaging system provides a clear and detailed display. Automatic optical zoom and laser red dot alignment enable components to be positioned precisely. The alignment accuracy is ±0.02 mm, which is particularly important for fine BGA components.
Fast heating and cooling with efficient IR technology
The IR preheating zone uses a medium-wave ceramic infrared heating plate with even heat distribution. A movable PCB holder and a BGA support frame enable flexible working. The integrated cooling system with laminar air flow ensures controlled and rapid cooling after the reflow process.

Hot air vs. infrared – the key differences
The main difference between a hot air rework station and an infrared BGA rework station lies in the type of heating used.
Hot air systems use heated air to heat the solder joints. Infrared systems such as the ZM-R7220A use IR radiation to heat each solder joint specifically until the solder melts.
Another advantage of infrared technology is its more precise temperature control. While hot air stations are usually based on PID control, the ZM-R7220A uses a PPM (Proportional Pressure Modulation) system that detects and corrects pressure and temperature changes within milliseconds. This allows the system to react more quickly and prevents thermal damage to sensitive components.
There is also a difference in cooling: IR systems do not require a strong air flow, as cooling is achieved through controlled air circulation within the system – ideal for consistent results without deformation of the circuit board.
