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.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with more than 24 years of experience in R&D, production, and after-sales service. It provides 3D software design, broad customization, ODM, and OEM services, and has exported soldering equipment to 16 countries. Manufacturing-related evidence includes valid contracts with associated subcontractors, inventory capability, product inspection procedures, and quality assurance processes. The supplier holds an ISO9001:2015 certificate and has an environmental impact assessment report and recent fire-drill records. However, no new products were reported in the past year, and the available financial information contains zero values for the stated prior-year operating metrics; financial credibility therefore cannot be positively assessed. The supplier has no overseas warehouse, showroom, agent or branch, and reports no offline trade-show participation.

Supplier typeThe supplier explicitly identifies as a professional technical supplier and operates in manufacturing, metal-product R&D, hardware manufacturing, and mechanical-equipment sales. Its stated experience covers R&D, production, and after-sales service, supporting classification as a technical manufacturing supplier.

CertificationsThe supplier holds an ISO9001:2015 certificate. It also reports a factory environmental impact assessment report, while its quality assurance, corrective-action, complaint-handling, and fire-drill procedures have documented implementation evidence.

After-Sales capabilityThe supplier states that it has more than 24 years of after-sales-service experience, inventory capability, and documented procedures for customer complaints and corrective and preventive actions. However, it has no overseas warehouse, showroom, agent, or branch, which limits directly evidenced overseas service coverage.

R&D capabilityThe supplier provides R&D capability, 3D software design, an available SDK, ODM services, and multiple customization modes. However, it also reports no new products during the past year, so current product-innovation activity is not clearly strong.

Production capacityThe supplier reports more than 24 years of production experience, a manufacturing business scope, valid manufacturing contracts with associated subcontractors, inventory capability, and uniformly followed finished-product inspection instructions. Quality assurance and corrective-action procedures are also documented, providing explicit evidence of production and quality-management capability.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. Its R&D offering also includes 3D software design, ODM, and OEM services, demonstrating broad stated customization coverage.

Client casesThe supplier states that its soldering equipment has been exported to 16 countries across Asia, Europe, and North America, and that it provides OEM services for well-known brands. These statements constitute evidence of international and branded-customer experience, although no specific customer names or project details are provided.

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.
