JJY solder Paste Manufacturer will explain some processes of lead-free solder paste reflow

AlthoughSolder pasteWhat the users have learnedSolder paste manufacturerNot many, but when it comes to some processes of lead-free solder paste reflow, there are not many left. SoLead-free solder pasteIn the process of facing the hot zone, what kind of link is the flux paste reflux? Next, let JJY Solder Paste Manufacturer provide some process answers for our partners:

Organic solvents have the characteristics of viscosity coefficient and screen printing ink. To avoid excessive temperature and the formation of small tin particles, the working temperature should be slow. For electronic components that are sensitive to their internal structure, excessive temperature will lead to an excessive number of defective products.

When the temperature gradually rises, the particles of the solder wire dissolve, and at the same time, it begins to vaporize and the "lamplight" operation process of the solder wire is absorbed on the surface. Then on different surfaces, solder spots gradually appear.

When solder wire particles continuously dissolve, liquid tin will be produced. At this time, if the distance between electronic components and solder layers is too large, the probability of separation is also high, which can easily cause short circuits and other adverse situations of solder spots.
