ZM-R730A semi-automatic BGA soldering machine

ZM-R730A semi-automatic BGA soldering machine – precision for large printed circuit boards

The ZM-R730A semi-automatic BGA soldering machine is specially designed for reworking large printed circuit boards. It combines precise temperature control, HD optical alignment, and intelligent control in a robust and user-friendly machine. This soldering station is a powerful tool for electronics manufacturers who require the highest quality in BGA and SMD repairs. As one of the leading suppliers of rework stations, Zhuomao guarantees durable products and consistently precise results.

Stable temperature control for precise soldering

The ZM-R730A has three independently controllable temperature zones that are heated by convection hot air. The lower zone is height-adjustable, while the upper zone has an integrated vacuum suction nozzle. Negative pressure monitoring and pressure protection ensure maximum safety during the soldering process. This combination guarantees uniform heating and prevents thermal damage to sensitive components.

Large HD touchscreen and smart controls

The large HD touchscreen displays all processes in real time. Users can edit and analyze temperature curves and save up to 100 different profiles. The system uses a Panasonic PLC controller and a K-type thermocouple with an accuracy of ±1 °C. PID multi-loop control keeps the temperature constant throughout the entire process. An integrated over-temperature warning function and software encryption increase operational safety.

Removable infrared temperature zone for flexibility

The infrared preheating zone is heated by a carbon fiber IR tube and covered by a microcrystalline protective plate. It can be moved sideways to easily maintain large or irregular boards. This makes work much easier and increases the longevity of the system.

Optical HD alignment for precise placement

With a 2-megapixel HD imaging system and laser red dot indicator, the ZM-R730A ensures precise optical alignment. The alignment accuracy is an impressive ±0.01 mm. This feature guarantees error-free placement of even the smallest BGA components.

ZM-R7220A BGA infrared soldering station

ZM-R7220A Infrared SMD Rework Station

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.

Technical specifications of the ZM-R7220A

  • Power supply: AC220V ±10% 50/60 Hz

  • Power: 5.65 kW (max.)

  • PCB size: max. 412 × 370 mm

  • Alignment accuracy: ±0.02 mm

  • Temperature accuracy: ±3 °C

  • Display: 15″ SD industrial display

  • Weight: 76 kg

  • Positioning: V-groove with universal mounting

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.

Zhuomao – Quality and Innovation

Zhuomao has been synonymous with high-quality rework technologies for years. The ZM-R7220A infrared SMD rework station combines efficiency, precision, and user-friendliness. Thanks to innovative sensor technology, fast heat transfer, and optical control, it is ideal for repairing modern electronics.
