Product Description product description

Halogen-free and lead-free high-temperature solder paste<="">

LFP-JJY5RQ-305T4 QFNSpecial halogen-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 and has excellent environmental protection characteristics. At the same time, the paste, which is refined with imported chemical materials, can achieve very high stability and effect.

It is suitable for welding bare copper or nickel-plated electronic components, hardware, electronic casings and other products that are prone to oxidation.QFNIt can be reached by climbing tin75~95%. The welding process can be carried out directly without the addition of additional flux.

The solder paste contained in this product complies with the standards of the United StatesQQ-571As stipulated in itRMAType and passSGSTest compliantRoHSInstruction requirements.

Product Features Product characteristic
  • 1 The weld points are firm, bright and full 12With years of R&D and production experience, we have scientifically mastered modern process formulas, ensuring that the solder paste is highly compatible with the soldered products. The solder joints are firm, bright, uniform, full and free of solder beads.
  • 2Low residue, no need for cleaning We have developed and formulated a no-wash environmentally friendly flux, which leaves little residue after welding, has high insulation resistance, a clean board surface without corrosion, and forms a protective layer to prevent the substrate from oxidizing again.
  • 3 It has strong wettability and good tin crawling High-performance thixotropic agents are added to the solder, making the solder paste highly active. The molten solder paste significantly wets the solder pad, reducing the phenomenon of false soldering during the soldering process.
  • 4 The printing is stable and has good demolding properties The tin powder particles have good roundness and uniform size. During printing, there is no trailing, sticking or splashing phenomenon. There is no collapse, sharp or continuous tin connection during molding. The viscosity change is small during continuous printing, and it does not dry out. The components do not shift.
Instructions for Use Instructions for use
Instructions for Use in5-10℃The storage period under the environment is6Months, not less than0℃Store under such conditions and thaw before use2-4It should be left to room temperature for more than an hour before opening to prevent the formation of tin beads due to moisture. Then stir well before use.
