Oversized Forced Hot-Air Convection Preheat Zone: Maximizing Capacity & Throughput

The Manncorp 45.400 wave soldering system comes equipped with a 5.9' (1.8-meter) forced hot-air convection preheat zone, divided into three independently controlled bottom-side heating zones. This extended preheat length ensures precise temperature profiling for lead-free wave soldering, allowing for higher conveyor speeds while maintaining optimal soldering quality—especially for high-mass PCBs.

For applications requiring greater thermal control or for assemblies sensitive to top and bottom temperature differentials, an optional top-side preheat system can be added. This upgrade includes three additional independent heating zones for enhanced process flexibility and consistency—all at a minimal additional cost.

The system is managed via a Windows^®-based user interface, providing full temperature profiling, real-time monitoring, and data recording capabilities to ensure maximum process control and repeatability.

External Spray Fluxer & Filtration System: Enhanced Performance, Reduced Maintenance

One of the standout features of the Manncorp 45.400 wave soldering system is its modular external spray fluxer with an integrated filtration system, designed to improve performance while minimizing maintenance. By separating the fluxer from the preheat zone, this design prevents flux residue buildup, extends equipment lifespan, and allows for reclamation of unused flux, reducing waste and operating costs.

The servo-controlled, reciprocating Y-axis spray nozzle assembly ensures even and precise flux application, utilizing a high-precision, low-pressure atomizer for superior coating and through-hole penetration. To maintain a clean working environment, the system features an advanced dual-zone filtration and flux reclamation system, which captures diffused flux vapors before they reach the heating chamber or exhaust vents. Collected flux is filtered and recycled, further optimizing efficiency.

With a drawer-style design for easy access to all components, the system is fully serviceable from outside the main heating chamber, dramatically reducing maintenance time and flux consumption while ensuring consistent, high-quality soldering results.

Advanced Wave Soldering Technology for Superior Flexibility

Our dual-wave soldering system is designed to provide exceptional precision and adaptability for all your assembly requirements. Driven by two powerful 1/4 HP motors with transducer control, it ensures precise wave height regulation for consistent, high-quality soldering results.

The primary chip wave generates a turbulent crest, ensuring thorough solder coverage to eliminate skips and defects. Following this, the main wave enhances joint quality by effectively removing excess solder, reducing bridging and buildup. For added versatility, operators can deactivate the chip wave via the user interface when working with non-SMT boards.

Featuring a standard 16" (410 mm) wave width, the system also includes a wave reducer to accommodate specific PCB sizes while minimizing dross formation. Intelligent features such as board interval sensing and an energy-efficient standby mode further optimize performance while reducing dross waste.

Dual-Solder Flexibility with Quick-Change Technology

The Manncorp 45.400 delivers exceptional versatility through its innovative solder pot system. The standard configuration features a high-capacity titanium-alloy pot that holds approximately 925lbs (420 kg) of solder, suitable for both leaded or lead-free applications. Mounted on a robust carriage with motorized Y-axis and Z-axis controls, the system ensures easy access and simplified maintenance.

For manufacturers requiring maximum flexibility, our dual-pot option enables seamless switching between solder compositions. This quick-change capability proves invaluable for facilities transitioning to lead-free production or contract manufacturers handling mixed-solder requirements. Simply exchange the entire carriage and pot assembly to switch between different solder types, minimizing downtime and maximizing production flexibility.

Enhanced Flexibility with Nitrogen Atmosphere & Forced Cooling Options

Recent studies suggest that wave soldering in a nitrogen atmosphere can enhance solder wettability and significantly reduce dross formation compared to traditional air-based processing. While the debate over nitrogen versus air soldering continues, the Manncorp 45.400 offers the flexibility to support both environments, ensuring adaptability to your specific manufacturing needs.

For those opting for the factory-installed nitrogen (N₂) option, the system replaces the standard hot-air convection preheater with a specially sealed IR preheater, designed to minimize nitrogen consumption. Additionally, an integrated nitrogen flow control system and PPM O₂ analyzer ensure that oxygen levels remain below the allowable threshold, maintaining a controlled soldering atmosphere for superior process stability.

Further research indicates that aggressive cooling rates (> 3.5°C/sec) can improve solder joint grain structure and reduce peak temperature exposure times. To accommodate this, the 45.400 offers an optional external chiller unit, enhancing the performance of the standard upper and lower forced cooling system, ensuring optimal cooling efficiency and solder joint reliability.

Streamline Production with Inlet and Unload Conveyors

Manncorp’s WL-100M-L1 Wave Solder Loader and WU-120M-H1 Wave Soldering Belt Unloader are engineered to optimize the efficiency of wave soldering systems.

The WL-100M-L1 Wave Solder Loader is a fully adjustable, chain-driven inlet conveyor that smoothly transfers assemblies up to 13.78" (350 mm) wide into the wave soldering machine. Designed for durability, it features a robust aluminum frame, along with adjustable speed, conveyor angle, and height to ensure seamless operation.

For efficient post-soldering handling, the WU-120M-H1 Wave Soldering Belt Unloader utilizes a heat-resistant, non-slip belt to safely transport soldered assemblies. Its adjustable height, angle, and speed—ranging from 1.5 to 26.2 ft/min (500 - 800 mm/min)—provide precise control, ensuring a smooth transition from the wave soldering system to operators or downstream processing equipment.
