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 solder paste manufacturing factory located in Shenzhen, China, serving electronics manufacturers across Vietnam with direct supply of solder paste, solder wire, and solder bar. Our production facility spans 5,000 sqm and is equipped with 96 sets of precision production and testing equipment, enabling consistent quality control across all product lines.
Local Vietnamese electronics assemblers frequently encounter challenges such as performance variation between solder paste batches, elevated procurement costs from imported materials, soldering defects including bridging and cold joints, and limited access to timely technical guidance. To resolve these, we coordinate with dedicated logistics partners to ensure reliable delivery to major industrial zones in Ho Chi Minh City, Hanoi, and Da Nang — using temperature-stable packaging tailored for tropical climate conditions.
Our product portfolio for the Vietnam market includes lead-free solder paste, high-temperature solder paste, water washable solder paste, low-temperature solder paste, and QFN-optimized formulations, alongside compatible solder wire and solder bar in standard and custom alloy compositions. We also supply no-clean and water washable fluxes to support full process integration.
A representative customer case involves a Tier-2 EMS provider in Bac Ninh province that transitioned from intermittent regional distributors to our direct supply model. This shift improved paste lot-to-lot consistency, reduced material cost by 12 percent, and enabled rapid remote troubleshooting during reflow profile optimization. Sample shipments are dispatched within 48 hours via express courier, and our SMT process engineers provide real-time online support for stencil design, printing parameters, and reflow profiling.
