The current general development trend of reflow soldering technology is to require reflow soldering to adopt more advanced heat transfer methods to achieve energy saving, uniform temperature, suitable for the welding requirements of double-sided PCB and new device packaging methods, and gradually realize a comprehensive replacement of wave soldering .

Reflow soldering process control technology

Guang Shengde intelligent reflow oven has a built-in computer control system. In the Window operating environment, various data can be entered conveniently, and the reflow soldering process curve can be quickly retrieved from the memory or replaced, saving adjustment time and improving production efficiency.

The purpose of process control is to achieve the two goals of the required quality and the lowest possible cost. Process control is the ability to obtain relevant data in a specific operation that affects the final result. Once a potential problem occurs, it can receive relevant information in real time, take corrective measures, and immediately adjust the process to the best condition. In the past, process control mainly focused on the detection of defects to improve quality; now, the most basic meaning of control is to continuously monitor various processes and find deviations that do not meet the requirements. Monitoring the actual process data is the real process control. In the reflow soldering process control, it means monitoring the thermal curve of each board manufactured.

Replaceable assembly and reflow soldering technology process

In recent years, alternative assembly and reflow technology (alternative assembly and reflow technology, AART) has aroused interest in the PCB assembly industry. The AART process can perform reflow soldering of through-hole components and surface mount components at the same time, eliminating wave soldering and manual soldering. Compared with the traditional AART process, it has less cost, cycle and defect rate. Through the AART process, a complex PCB assembly process can be established. AART must consider materials, design, and process factors that affect it. Decision Support System (DSS) can help engineers implement AART process.
