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 plants across IndonesiaKarawang with consistent, high-reliability solder materials including solder paste, solder wire, and solder bar.
A local PCB assembly line in IndonesiaKarawang previously experienced frequent solder joint defects and inconsistent reflow performance using imported lead-free solder paste. After switching to our standardized SAC305-based solder paste formulation with optimized metal load and rheology control, their defect rate dropped significantly in QFN and fine-pitch component placement applications.
Our product portfolio delivered to IndonesiaKarawang includes lead-free solder paste for standard reflow, medium-temperature solder paste for heat-sensitive components, water washable solder paste for post-solder cleaning requirements, and matching solder wire and solder bar for hand soldering and wave soldering integration.
Applications span automotive electronics modules, consumer power supplies, and industrial control boards produced in IndonesiaKarawang facilities. We support process validation through remote engineering consultation and provide sample kits with temperature-stable packaging via dedicated courier channels.
All products are manufactured in a 5,000 sqm GMP-aligned facility equipped with automated mixing, viscosity monitoring, and particle size analysis systems — ensuring batch-to-batch consistency critical for SMT line stability in IndonesiaKarawang operations.
