smtSurface mount technology (SMT) is the driving force for the vigorous development of the electronics industry and has made tremendous contributions to its growth.smtA kind of solder paste excipient is needed for surface mount technology.Solder pasteissmtSo, what are the functions of solder paste? It is essential for surface mount technology. Today, Shenzhen JJY Solder Paste Manufacturer will elaborate on this topic:

What is solder paste

The form of solder paste is similar to that of a paste, being viscous. It is usually stored in the refrigerator (if placed at room temperature, the solder paste will solidify, affecting its normal use). Before use, it needs to be taken out to warm up and then stirred evenly before use (the function of stirring is to ensure that the tin powder alloy particles and the flux are fully and evenly mixed, because after being stored for a long time, the solder paste Tin powder particles will settle to the bottom.

The composition of solder paste

Solder paste is a paste-like substance. It is composed of solder powder particles, alloys and fluxes. Solder powder particles can be used for reflow soldering and hot melt soldering of electronic components. Fluxes include resins, rosin, active agents, thickeners and solvents. Each element plays a different role during reflow soldering (for example, active agents can clean the stains and oxides on the solder joints during soldering) To make the solder joints full, round and shiny, the thickener is used to make the solder paste sticky.

The function of solder paste

The main functions of solder paste are twofold. On the one hand, it can adhere to electronic materials during the placement process by the surface mount technology (SMT) machine. On the other hand, during the soldering process, it can melt and fix the electronic materials on the solder pads.

The flux in solder paste contains resin, rosin, active agent, thickener and solvent.
