1. Stable performance, not easy to age, suitable for various temperature and humidity environments.
2. The residue is transparent, does not affect the beauty and cleanliness of the circuit board, and does not cause corrosion and damage to the circuit board.
3. The reflow process window is wide, adapting to different reflow equipment and parameters, with good welding effect and no welding defects.
4. Needle probe test can be performed without damage to the needle probe equipment or affecting the accuracy of the test.
5. Excellent wetting performance, whether it is high peak or low peak, it can quickly wet the pad, making the solder joint bright and full, and there are very few through-hole voids.
6. High welding reliability, although the activity is slightly weak, it can effectively reduce welding defects such as holes and cracks, increase the impedance of residues, and reduce the risk of "leakage".
7. Halogen-free solder paste is a solder paste with higher environmental protection requirements. It can reduce pollution to the environment, protect human health, and improve the quality and life of electronic products. The cost of halogen-free solder paste is relatively high, but in the long run, it is a value-for-money choice.
