How difficult is programming, and how soon can operators run the machine?

Programming is intentionally simple. Import PCB images or Gerber data, then move the cursor to define spray/weld points or draw lines-no complex coding required. With 1-2 days of on-site training, most line operators master programming, daily operation, and preventive maintenance. Combined with lifetime remote technical support, your team will be fully self-sufficient.

Can I send my PCBs for a free trial run before purchasing?

Yes-we strongly encourage it. Sending us a few bare boards (plus fixtures if available) lets us perform a complimentary soldering trial. We'll return the soldered samples along with high-resolution videos, cycle-time analysis, and process validation data, giving you tangible proof of capability before you invest.

Product Q&A

Q:What's the lead time for orders?

Standard models ship in 10 days; customized units require 10~15 days.

Q:What documents do you provide for export?

Full export package (Commercial Invoice, Packing List, Bill of Lading, COC, etc.).

Q:How do I place an order?

Q:Do you accept customization?

Yes,We can provide OEM service.Customize the machine size and function for your product.

Q:How many boards per hour can a compact/offline selective soldering machine realistically produce?

Real-world throughput depends on component mix, solder joint distribution, and nozzle size. For example, soldering a 4-pin component in one shot with a large-diameter nozzle is roughly 4x faster than sequential spot soldering with a fine nozzle. To give you an accurate number, share your PCB details and we'll model a realistic cycle time tailored to your product.
