Product Overview

This compact, energy-efficient equipment integrates full flux spraying and soldering processes into a single footprint, delivering professional-grade soldering performance at an accessible cost point. Unlike traditional soldering solutions, this offline selective wave soldering machine completes soldering through a fixed solder pot and movable PCB design, supporting PCB sizes from 60×40mm up to 330×250mm. With manual PCB loading and unloading, it offers exceptional flexibility for prototype verification and product iteration, while preheating functions and machine dimensions can be fully customized to match unique production requirements. It is the ideal soldering solution for electronic product development teams and manufacturing enterprises focused on agile production.

Product Advantages

Cost-Effective & Space-Saving Design

With overall dimensions of just 1050×1050×1400mm, this benchtop selective soldering machine has a minimal footprint, fitting easily into limited workshop spaces. Its total power of only 5.5KW ensures ultra-low energy consumption, drastically reducing long-term operating costs for production facilities. Manual PCB handling eliminates complex automation infrastructure investment, with low tooling costs and minimal maintenance requirements for small to medium production runs.

Stable, High-Yield Soldering Performance

The FS-250C delivers consistent high-quality soldering with an exceptional yield rate, eliminating common soldering defects and reducing rework costs. It features a full nitrogen protection system covering the nozzle and solder pot, with digital flow control for stable soldering conditions. The PC + motion control card system enables precise parameter management, ensuring uniform soldering results across every production batch.

Flexible Process Adaptability

This PCB selective soldering equipment supports fully customizable preheating functions and dimensions, adapting to diverse PCB designs and production needs. Its flexible process configuration makes it suitable for multi-variety, small-batch production, with the ability to adjust soldering parameters for different product lines without extensive retooling.

Product Applications

The FS-250C selective wave soldering machine is widely used across multiple high-reliability industries, including military electronic equipment manufacturing, automotive electronics assembly, aerospace component production, communication equipment fabrication, medical device manufacturing, home appliance production, new energy product assembly, and digital product manufacturing. It is particularly optimized for PCB NPI, prototype development, and small-batch production, serving the core needs of R&D departments and electronic manufacturing enterprises with frequent product updates.
