XD-S Series Offline Selective Wave Soldering System achieves precise soldering points, flexible and easy to debug, suitable for small and medium batches of various PCBs.

Why choose this product?

XD‑S Series Offline Selective Wave Soldering System is a high-performance offline selective wave soldering system. Choosing the XD-S Standalone Selective Wave Soldering System enables targeted THT soldering on PCBA and precisely avoids SMD components to prevent circuit board damage caused by high temperature. The XD-S Standalone Selective Wave Soldering System supports standalone offline operation without connecting to a complete DIP production line for flexible layout. Its targeted soldering mode greatly saves solder and flux consumption. Featuring fast program switching, it fits multi-variety R&D sampling and small-batch DIP production. With compact structure and easy parameter tuning, the XD-S Standalone Selective Wave Soldering System is the preferred equipment for flexible selective soldering.

How It Works

  • XD-S Batch Selective Wave Soldering loads PCBs to be soldered. The system imports the soldering program and presets parameters including soldering coordinates, temperature and dwell time.
  • Servo drive mechanism accurately moves PCB or solder pot module to position target solder joints.
  • Special micro nozzle generates controllable micro solder wave, applying solder locally only on designated joints.
  • Nitrogen protection covers the soldering zone continuously to minimize solder oxidation and improve joint quality and reliability.
  • Closed-loop temperature control stabilizes solder pot temperature to prevent thermal damage to surrounding precision components.
  • After single-point soldering, the system automatically switches to the next joint and completes all selective soldering sequentially.

Application Process

  1. Manually place and fix PCBs on tooling fixtures.
  2. Import soldering files and set process parameters: coordinates, temperature, dwell time, etc.
  3. Start XD-S Batch Selective Wave Soldering System. The solder pot heats up to the set temperature and completes constant-temperature preheating.
  4. Servo module drives workpiece to accurately move to the first soldering position.
  5. Micro nozzle rises to generate micro solder wave under nitrogen protection for point soldering.
  6. Upon completion of single-point soldering, nozzle retracts, and the system automatically moves to the next joint.
  7. Once all joints are processed, the workpiece returns to loading/unloading station.
  8. Operator unloads finished PCBs, inspects solder joints and replaces new workpieces.

 

Requirements

FAQ

How to choose between single-wave and dual-wave soldering?
  • Single-wave is recommended for simple single-layer PCBs with sparse components to lower investment. Dual-wave is preferred for boards with high-density through-hole parts, abundant connectors and mixed assembly, which reduces the rate of missing solder and bridging defects.

Do you provide after-sales service?

  • Our professional after-sales service team will quickly resolve any emergencies you may encounter during use.

Warranty period?

  • -The entire machine is covered by a one-year warranty, with free technical support provided after that year.

Do you provide installation and commissioning?

  • On-site installation and commissioning will incur additional fees, including accommodation and airfare.

Shipping method?

  • Typically, shipping is by sea or land. Air freight is more expensive for urgent needs.
