The Turntable Selective Wave Soldering Machine RS-D2 is a professional-grade offline dual solder pot system engineered specifically for high-volume, high-precision production of small-size PCB assemblies. This advanced soldering equipment features an innovative dual-station synchronous design, enabling parallel processing that significantly increases production throughput while maintaining strict soldering accuracy. By integrating manual feeding, automatic flux spraying, preheating, and automatic soldering into one optimized workflow, this machine ensures consistent quality across large production runs. Each individual solder joint can be programmed via computer-controlled parameter settings, allowing for tailored thermal profiles. With an intuitive operation interface and fully traceable production procedures, the RS-D2 serves as a highly efficient soldering solution for large-scale manufacturing facilities and consumer electronics enterprises looking to upgrade their assembly lines.


Product Advantage


  • This equipment includes manual feeding station, automatic spraying station, preheating station, and automatic soldering station.

  • The rosin flux nozzle can move along the XY axis.

  • There is a soldering furnace, which can move along the XYZ axis, and an N2 protection device is installed in the soldering furnace.

  • Multiple stations can work at the same time to improve work efficiency.


Product Application


The RS-D2 turntable selective wave soldering machine is engineered for versatility and reliability across a wide range of demanding industries. It is specifically optimized for the mass production of small-size PCBs up to 100×100mm. This makes it an ideal investment for manufacturing facilities with standardized product lines requiring consistent, high-yield outputs. The equipment is widely deployed in sectors requiring stringent quality control, including military electronics, aerospace, medical devices, new energy systems, automotive electronics, communication equipment, home appliance manufacturing, digital product assembly, and stage lighting controls.

Product Operate Guide


This programmable selective soldering machine operates on a reliable industrial PC paired with a motion control card system, supporting multiple soldering modes to adapt to diverse product requirements. Operators can easily configure distinct parameters for each specific solder joint, achieving precise control over soldering height, temperature, and travel speed through the intuitive PC interface. The system allows for flexible programming via direct image, GERBER, or CAD file imports, which eliminates the need for complex manual programming and significantly reduces setup time during product changeovers. All PCB process parameters can be set, saved, and accessed directly on the PC screen. Additionally, the machine features built-in PCB counting, real-time system messaging, and automated alarm functions to ensure complete production traceability. Our technical support provides comprehensive training to ensure operators can master the equipment efficiently.

Q:How does your factory control the quality ?

A:  We keep a very stable quality level for years , and qualified products rate is 99% and weare constantly improving it, before shipment, we will arrange two days for 100%  quality inspection.


Q: What is the difference between offline selective soldering and online selective soldering?

A: Online selective soldering has a track system that connects the front-end and back-end production processes, supporting the simultaneous preheating and spraying of flux and soldering modules in a closed space.


Q:Why is there such a big price difference between online and offline equipment?

A: Online equipment requires more raw material production cost and technical cost because of its complex structure, supporting more comprehensive performance and functions to achieve efficient fully automated production.


Q: When can I receive a quote?

A: We usually provide a quote within 24 hours after receiving your inquiry. If you need an immediate response, please call us or contact us via WhatsApp, and mention this in your email so that we can prioritize your inquiry.


Q: Do you provide customized services?

A: Yes, we provide OEM services. The machine size and functions can be customized according to your needs.


Q: What is the delivery time of your products?

A: The standard delivery time is within 35 working days after receiving payment.


Q: What is the difference between AS-350C and XS-350C selective soldering machines?

A: Both are online selective soldering machines, but XS-350C is designed for mass production work, especially for new energy products, energy storage products, automotive electronics, etc. You can choose the machine according to your product characteristics, or tell us more details about your product, we will recommend the most suitable machine for you according to your product.
