JJY Tinsolder Brand
Localized supply of professional electronic soldering materials, a one-stop purchasing solution for solder paste, solder wire and solder bar, with sample trials and technical support.
We are a Shenzhen-based solder paste manufacturing facility serving electronics assembly companies in VietnamDa Nang with direct supply of solder paste, solder wire, and solder bar. Our production base covers 5,000 sqm and operates 96 sets of precision production and testing equipment to ensure stable material properties across all batches.
A local VietnamDa Nang electronics contract manufacturer previously experienced recurring bridging and cold solder joints using imported solder paste, with no access to on-site process engineers. After switching to our lead-free SMT solder paste and matching solder wire, they achieved improved stencil release and joint reliability—supported by remote SMT process tuning from our engineering team.
Our product portfolio includes lead-free solder paste, high-temperature solder paste, water-washable solder paste, low-temperature solder paste, QFN-optimized solder paste, and LED-specific formulations. Complementary offerings include solder wire and solder bar in standardized diameters and alloy compositions, along with no-clean and water-washable flux options.
All shipments to VietnamDa Nang use constant-temperature packaging to maintain rheological integrity during transit. We coordinate with dedicated logistics partners to ensure predictable delivery timelines. Stocked standard products ship within 48 hours; custom formulations follow confirmed production scheduling. Sample kits are dispatched via express courier with full technical documentation.
Technical assistance includes real-time remote support for reflow profile optimization, solder paste storage handling, and defect root cause analysis. For qualified volume commitments, on-site consultation can be arranged to align process parameters with material behavior and equipment capabilities.
