The built-in computer control system in the intelligent reflow furnace can easily input all kinds of data in the operating environment of Window windows. It can quickly remove or replace the process curve of reflow welding from memory, so as to save time and improve production efficiency.

The purpose of process control is to achieve the two objectives of the required quality and the lowest possible cost. In the past, process control was mainly focused on the detection of the lack of strangers, in order to improve the quality. After development, the most fundamental connotation of control was to monitor the various processes continuously, and to find out the deviations that did not meet the requirements. Process control is the ability to obtain relevant data in a specific operation that affects the final result. Once the potential problem appears, it can receive the relevant information in real time, take corrective measures, and adjust the process to the best situation immediately. Monitoring the actual process data is a real process control, which means monitoring the heat curve of each plate made in the reflow process control.

An automatic management system that can monitor the reflow furnace continuously. It can indicate whether the process is out of control before the actual process shift. This is the automatic reflow Management (AutomaticReflowManagement, ARM) system. This system consists of a continuous SPC histogram, line balance network, file compilation and product tracking. The basic function of the automatic reflow welding management system is to automatically detect and collect the product data through the furnace. It provides the following functions: no need to verify the process curve; to automatically collect reflow process data; to provide real-time feedback and alarm for the zero defect production; automatic SPC diagrams and corrections for reflow process.
