Low-residue solder paste is a key material for enabling SMT no-clean processes. It can control ionic residues below 10.06μg/cm2 NaCl equivalent after reflow soldering, avoiding leakage, corrosion, and CAF failures caused by rosin or organic acid residues. It is especially suitable for high-density, fine-pitch automotive-grade and medical electronics assembly without underfill.

In 2018, a trend of solder paste formula optimization emerged in the electronics manufacturing industry, and enterprises began to pay attention to the application scenarios of environmentally friendly and low-residue solder pastes. With increasingly strict environmental regulations and rising industry demand for high-precision manufacturing, solder paste technology is gradually developing in the direction of low harmful substances and high stability.
Published: 2019-01-01High-frequency PCB soldering is extremely sensitive to the halogen content and residue control of solder paste. Jiajinyuan halogen-free low-residue solder paste, by optimizing the rosin system and activator ratio, ensures wettability while reducing ionic contamination to below 0.25μg/cm2, significantly minimizing impedance fluctuations and phase shifts in high-frequency signal transmission.
Published: 2016-12-13Low-residue solder paste and no-clean solder paste are becoming key choices for cost reduction and efficiency improvement in high-density PCBA production lines. Domestic solder paste has already demonstrated the capability to replace imported alternatives in terms of halogen control, solder climbing performance, and thermal stability. The Jiajinyuan 8MNTTP/5RNTT series achieves ultra-low halogen levels of 100~200ppm with transparent residue, while the 8M9P/5RR series reaches 0ppm zero halogen with extremely low voidage, making it suitable for high thermal reliability scenarios such as automotive lighting.
