Although users may not have learned much about Solder paste from a Solder paste manufacturer, when it comes to the reflow process of lead-free Solder Paste, there is even less known. So, for Lead-free solder paste, what exactly is the Flux reflux stage as it enters the hot zone? Next, let JJY Solder Paste Manufacturer provide some process answers for partners:
Organic solvents have viscosity and screen-printing characteristics. To avoid excessive temperature and the formation of small solder beads, the working temperature should be raised slowly. For electronic components sensitive to internal structure, excessive temperature will lead to an excessive number of defective products.
As the temperature gradually rises, the solder powder particles dissolve, and the flux begins to vaporize; the activation process of the solder powder is absorbed on the surface. Then, on different surfaces, solder joints gradually form.
When solder powder particles continuously dissolve, liquid tin is produced. At this time, if the distance between electronic components and pads is too large, the probability of separation is high, which can easily cause short circuits and other solder joint defects.
