Key Factors to Consider When Selecting a Reflow Soldering Equipment Manufacturer

When selecting a reflow soldering equipment manufacturer, it is essential to comprehensively evaluate the following critical factors to ensure that the equipment performance aligns with production requirements and guarantees long-term stable operation:

‌1. Core Performance Parameters of the Equipment‌

‌Temperature Uniformity and Precision‌

The temperature difference in the soldering area must be controlled within ±1.5°C, with temperature control precision of ±1.0°C being the industry's high standard.

Testing method: Cross-sectional temperature difference <0.5℃ (no load), and temperature difference between boards ≤1℃ under full load.

Heating System Design

Prioritise custom heating wires (treated at 1200℃) combined with nano-coated turbulent plates, which improve thermal efficiency by 20%.

The number of heating zones must be ≥4, including an independently temperature-controlled lower heater, and support hot air + infrared compensation technology.

‌Heat Loss Control‌

Multi-layer insulation structure saves over 15% energy, reducing long-term energy costs.

‌Conveying Stability‌

Split-type design + servo motor drive, vibration amplitude must be close to zero (to prevent component displacement).

‌II. Manufacturer's Technical Capabilities and Production Capacity‌

‌R&D Capabilities‌

Verify technical patents, proprietary intellectual property rights, and core process reserves such as hot air micro-circulation.

‌Production Scale Compatibility‌

Customise production lines based on product dimensions (e.g., select a ten-zone device for widths over 400 mm) and daily output (require large-scale equipment for over 5,000 pieces per day).

‌Process Compatibility‌

Support special processes such as lead-free solder and nitrogen welding; furnace chamber sealing must meet low-oxygen requirements.
