What are the advantages of halogen-free and lead-free high-temperature solder paste?

Halogen-free solder paste is a product specially designed forSMTHalogen-free production line designed and manufacturedLead-free and no-cleaning solder pasteThe product must passSGSInternational standard certification: Currently, the European Union has relevant regulations. At present, most electronic products must be halogen-free. Therefore, many companies choose lead-free and environmentally friendly products when selecting products, but there are also some that have strict requirements for halogens. Now, Shenzhen JJY Solder Paste Manufacturer will introduce this product to you:

Halogen-freeHalogenFree(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 than900ppmThe sum is less than1500ppmExceeding 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 approximately300℃. When burning, it will release halogenated gases (such as fluorine, chlorine, bromine, iodine, etc.))Absorb oxygen rapidly, thereby extinguishing the fire. However, its drawback is that when the concentration of the released chlorine gas is high, the reduced visibility will make it impossible to identify the escape route. At the same time, chlorine gas is highly toxic and can affect the human respiratory system. In addition, the halogen gases released by the combustion of halogen-containing polymers, when combined with water vapor, will produce 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-JJY5RNTT-305T4The advantages of halogen-free and lead-free high-temperature solder paste are mainly reflected in the following aspects:

1,LFP-JJY5RNTT-305T4(Pb<100ppmHalogen-free and lead-free high-temperature solder paste is adoptedSn96.5Ag3.0Cu0.5It 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,BGAMounting of precision components such as devices.

3It has extremely low halogen content, leaves little residue after welding, is fully transparent and non-corrosive. It has an extremely high surface insulation impedance value and can achieve excellent results without cleaningICTTest performance. Halogen100~200ppm.

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 its form remains intact after printing,It is not easy to collapse and avoids the displacement of surface mount components.

6After welding, the solder joint is bright, the solder creep is relatively high, the porosity is low, the electrical and thermal conductivity is excellent, and it is well suppressedBGAThe pillow effect.

7The anti-tin bead formula generates very few tin beads during soldering, reducing the occurrence of short circuits.

JJY Solder Paste Factory specializes in the production of various solder pastes, including leaded solder pastes, lead-free solder pastes, syringe solder pastes, water-washed solder pastes, and zero halogenREACHLead-free high-temperature solder paste, lead-free medium-temperature solder paste, highly reliable lead-free low-temperature solder paste, halogen-free solder pasteLEDSolder pasteQFNSolder pasteBGA/IGBT/MOS/High powerLEDLow-hole solder paste for high-power devices, die bonding solder paste, hardware solder paste, etc.
