Lead free hot air reflow soldering oven reflow soldering machine for smt

Lead free hot air Automatic selective hot air reflow soldering machine for pcb.

The reflow furnace process is to achieve soft brazing of mechanical and electrical connections between surface assembly component solder ends or pins and the pad by remelting the paste soft brazing solder pre-allocated to the pad. Reflow furnace is the last key process of SMT(surface mount technology), which is a real-time process control. The process changes are complicated and involve many process parameters, among which the setting of temperature curve is the most important, which directly determines the quality of reflow welding.
