What is halogen-free and what are the characteristics of halogen-free and lead-free high-temperature solder paste?

Nowadays, people are increasingly aware of environmental protection, and many companies are choosing productsWhen choosing lead-free and environmentally friendly products, it is preferred. There are also some with stricter requirements that have requirements for halogens. Now, the solder paste manufacturer will share with you:

Halogen-freeHalogen Free(HFIn fact, it is a requirement of countries with strict environmental awareness to ban related halides, which requires halogensF,Cl,Br,IThe contents are respectively less than900 ppmThe sum is less than1500 ppmExceeding this value is regarded as non-compliant. In fact, if halogens (fluorine, chlorine, bromine, iodine) are added to polymer products such as plastics, they can be used to increase the ignition point. The advantage is that the ignition point is higher than that of ordinary polymer materials, and the ignition point is approximately 300℃ . When burning, halogenated gases (fluorine, chlorine, bromine, iodine) are released, which rapidly absorb oxygen and thus extinguish the fire. However, its drawback is that when the concentration of chlorine gas released is high, the resulting reduced visibility can make it impossible to identify escape routes. At the same time, chlorine gas is highly toxic and can affect the human respiratory system. In addition, the halogen gas released by the combustion of halogen-containing polymers, when combined with water vapor, will generate corrosive and harmful gases (hydrogen halides), which can cause corrosion to some equipment and buildings. In fact, excessive halogen is harmful to some products and even to the human body.

The halogen-free and lead-free high-temperature solder pastes produced by JJY Solder Paste Factory all meet the halogen-free standard, and some models even do0Halogen, and it is also environmentally friendlyRoHS2.0Instruction requirements. Produced by our companyLFP-JJY1KR-0307T4The advantages of halogen-free and lead-free high-temperature solder paste are mainly reflected in the following aspects:

1,LFP-JJY1KR-0307T4(Pb<100ppmHalogen-free and lead-free high-temperature solder paste is adoptedSn99Ag0.3Cu0.7It is made of spherical solder powder of lead-free tin alloy with low oxidation degree, featuring superior environmental protection characteristics. Meanwhile, the paste refined from imported chemical materials can achieve high stability and effect.      

2It has good demolding performance during printing, excellent dry resistance and good thixotropic performance, and can be applied to general spacings≧0.3mmPrinting of solder pads and fine spacingQFN,BGAThe mounting of devices.      

3High temperature resistance300It does not turn yellow, leaves little and transparent residue after welding, is non-corrosive, and has an extremely high surface insulation resistance value. It can achieve excellent results without cleaningICTTest performance. Halogens are within the halogen-free limit900ppmWithin.     

4When printing continuously, the viscosity change is small, which can ensure the stability of the printing effect during long-term operation.      

5This product has excellent thixotropic performance and maintains a good shape after printing,It is not easy to collapse and avoids the displacement of surface mount components.      

6The weld points are bright after welding and have excellent electrical conductivity. Gold-plated sheet metalQFNThe tin climbing has a high fullness.      

7Fewer solder beads are produced during welding, reducing the occurrence of short circuits.      

Halogen-free solder pasteIt can be reflow soldered in an air furnace as well as in nitrogen. After reflow, there is no need for cleaning. The unique active system of halogen-free solder paste ensures the elimination of various reflow soldering defects and also guarantees the long-term stability of the solder paste.
