JJY briefly discusses the differences between solder paste and flux

Everyone should knowFlux pasteBoth flux and auxiliary electronic soldering materials are quite common in the electronics industry, such as circuit boards or other electronic products. These all require the use of auxiliary electronic soldering materials. So, do you know the differences between the two? The following is a brief discussion by JJY Solder Paste Manufacturer:

Both are fluxes. They can both remove oxidation, assist in heat conduction, reduce the surface tension of metals, and make the joints more stable, attractive and beautiful!

Fluxes are generally classified into three types: inorganic fluxes, organic fluxes, and rosin. 

Inorganic fluxes: such as orthophosphoric acidH3PO4Organic fluxes are primarily certain organic acids or organic halogens. Relatively speaking, inorganic fluxes have stronger activity and better effect in removing oxide films, but they are also highly corrosive and can easily damage metals and solder joints. Generally, they cannot be used in the soldering of electronic products.

Flux paste: A paste-like chemical substance that plays two main roles in the welding process: "removing oxides" and "reducing the surface tension of the material to be welded". It is widely applied in watch instruments, precision components, medical devices, stainless steel handicrafts, tableware, mobile communication, digital products, air conditioning and refrigerator refrigeration equipment, eyewear, knives, car radiators and all kinds of other productsPCBBoard andBGABrazing of tin balls

How do people distinguish them? It's very simple. It's easy to distinguish flux from solder paste. Just observe the color. The light yellow or brownish yellow one is solder paste, and the gray one is solder paste.

So what I want to tell everyone is that flux and solder paste, two different things, cannot be added randomly !Is the solder paste of the same type as the solder paste in the solder paste ? So it is, Adding flux paste is also acceptable....

Really not., Open a new bottle of solder paste, Just add some new solder paste to the old one...Isn't it about having high quality requirements, Simple welding of large components is also acceptable !So everyone should pay attention.
