The selection of low-temperature solder paste must closely align with the balance among the temperature resistance limit of devices, solder joint reliability, and the production line process window. Among domestic solder pastes, LFP-JJY2R-64351 (Sn64Bi35Ag1), LFP-JJY5RW1A-4258 (Sn42Bi58), and LFP-JJY5RG-In52Sn48 have been batch-verified in scenarios such as LED transparent displays, copper wire lights, and fingerprint locks. Combined with T3/T4 powder particle sizes and ROL1/ROL0 halogen control, they achieve a solder wetting rate of over 70%, a void rate of <8%, and transparent, non-corrosive residues within a 160–220℃ reflow window.
Published: 2009-05-29SnBi solder paste has become a key material for soldering heat-sensitive components due to its low melting point of 138–172℃. Domestic solder paste has achieved mass production of mature formulations such as Sn42Bi58 and Sn64Bi35Ag1 in the low-temperature solder paste field. The Jiajinyuan LFP-JJY2R-64351 and LFP-JJY5RW1A-4258 series have verified process stability in printability, wettability and low void rate in scenarios such as LED transparent screens, copper wire lamps and aluminum nickel-plated heat sinks.
