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 across Brunei. Our production base covers 5,000 sqm and is equipped with 96 sets of precision production and testing equipment, enabling consistent output of solder paste, solder wire, solder bar, and compatible fluxes.
A Brunei-based electronics contract manufacturer recently adopted our lead-free solder paste for automotive-grade PCB assembly. Facing recurring bridging and inconsistent reflow profiles with previous imports, they transitioned to our medium-activity, no-clean lead-free formulation — resulting in improved first-pass yield and reduced rework on QFN and fine-pitch components.
For wave soldering applications, we supply standardized tin-copper and tin-silver-copper alloy solder bars alongside matching low-residue solder wires. These are used by Brunei’s industrial control module producers in power supply and sensor interface board manufacturing, where thermal stability and wetting performance under variable preheat conditions are critical.
All shipments to Brunei utilize temperature-controlled packaging and coordinated courier services, ensuring paste rheology integrity and wire surface quality upon arrival. Stocked standard grades ship within 48 hours; custom formulations are scheduled based on confirmed order parameters. Remote SMT process support — including stencil design review, reflow profile optimization, and defect root-cause analysis — is provided by our engineering team to address real-time production challenges.
