What are the functions of various components in solder paste in the SMT industry?

With the continuous development and progress of the electronics industry, we all knowSMTWhat materials and products are often used in the industry, such as oursSolder pasteWhat are the functions of the various ingredients in its paste? Shenzhen JJY Solder Paste Manufacturer will present it to you one by one, hoping to be of help to you.

1Thixotropic agent(Thixotropic)This component is mainly used to adjust the viscosity of the solder paste and its printing performance,It plays a role in preventing phenomena such as trailing and sticking during printing;

2Activator(Activation)This component mainly serves to removePCBThe function of the oxide substance on the surface layer of the copper film pad and the welding part of the parts, and it also has the effect of reducing the surface tension of the alloy.

3Solvent(Solvent)This component is the solvent of the flux component and plays a role in regulating uniformity during the stirring process of the solder paste, having a certain impact on the lifespan of the solder paste.

4Resin(Resins)This component mainly serves to enhance the adhesion of the solder paste and can also protect and prevent itPCBOxidize again after welding; This component plays an important role in fixing the parts.

Shenzhen JJY Industrial Technology Co., Ltd. mainly engages in the production and operation of:SMTSolder paste manufacturers of solder paste, syringe solder paste, lead-free solder wire, wave soldering bar, automatic soldering wire, etc.
