Reflow Soldering Development Phase



According to the heat transfer efficiency of the product and the continuous improvement of welding reliability, reflow soldering can be divided into five stages of development.

First generation: Hot plate conduction reflow equipment: Heat transfer efficiency is slowest, 5-30 w/m2k (different material heating efficiency is not the same), there is a shadow effect.

Second generation: Infrared thermal radiation reflow equipment: Heat transfer efficiency is slow, 5-30w/m2k (different materials of infrared radiation efficiency is not the same), there is a shadow effect, the color of components on the heat absorption has a big impact.

Third generation: hot-air reflow soldering equipment: high heat transfer efficiency, 10-50 w/m2k, no shadow effect, color has no effect on the heat absorption.

Fourth generation: gas-phase reflow soldering system: High heat transfer efficiency, 200-300 w/m2k, no shadow effect, the welding process needs to move up and down, the cooling effect is poor.

Fifth generation: Vacuum steam condensation welding (vacuum vapor phase welding) system: Airtight space without empty welding, the highest heat transfer efficiency, the W-500W/M2K, the welding process to maintain static without vibration, excellent cooling effect, the color does not affect the absorption of heat.
