What effect does SMT reflow soldering furnace temperature curve setting on SMT soldering quality? SMT reflow soldering furnace temperature tester comprehensive process monitoring realizes intelligent closed-loop manufacturing, and improves the product quality of SMT electronics manufacturing.
With the rapid development of the electronics industry, high integration and high reliability have become a new trend in the industry. Driven by this trend, SMT (Surface Mount Technology) has also been further promoted and developed in China. Many companies have applied SMT technology and surface mount components (SMC/SMD) extensively in production and R&D. Therefore, the soldering process cannot avoid a large number of reflow soldering machines. Let's talk about some of our experience and views in the work for the setting of the reflow soldering temperature curve.
The furnace temperature curve of the SMT reflow soldering furnace temperature tester is generally set based on the solder paste you use, the components on the PCB and the materials it uses, and the temperature curve generated under different PCB environments It's different too! The temperature curve we tested is actually the temperature on the PCB board, not the temperature on the stove you see.
The SMT furnace temperature curve is a coordinate axis of the actual temperature and time of the reflow furnace. It can tell us at what time its temperature value was at that time, so as to obtain some important process parameters such as the heating slope, constant temperature time, reflow time, etc. And these process parameters are critical to the reflow of the entire product. We can use the furnace temperature curve to determine whether it matches the process of our solder paste and products, and then adjust the furnace temperature. As for the influence of different parameters on the entire process, I am afraid that we will have to slowly accumulate it through some theories and our own experience.
