Direct factory supply featuring pure rolled/electrolytic copper foils, glass cloth substrates, and high-performance adhesives tested to stringent global reliability standards.
Zhuhai Huayuan Electronics Co., Ltd. (operating advanced production bases in Zhuhai Nanping Science Park and Zhongshan Tanzhou) manufactures high-purity electrical shielding solutions. Comprehending the micro-structure of copper tape is paramount for critical applications.
We supply both Rolled Annealed (RA) copper for ultra-flexible dynamic flexing (FPCBs, automotive harnesses) and Electrolytic (ED) copper foils for high-tensile shielding enclosures, with foil thicknesses calibrated from 18μm to 70μm with ±1.5μm precision.
Our conductive acrylic adhesives utilize nickel-plated or silver-coated micro-spheres precisely dispersed throughout the adhesive layer. This delivers continuous through-plane (Z-axis) and in-plane (X-Y axis) conductivity, guaranteeing low surface contact resistance (<0.05 Ω/sq).
Standard copper foils degrade when exposed to moisture and industrial atmospheres. Huayuan applies a proprietary nanometer-thin anti-oxidation passivated coating that preserves solderability and electrical conductivity even under 85°C / 85% RH accelerated aging conditions.
