Three-Proof CPU Smart Card Circuit Board Encapsulation Module

Based on flexible printed circuit board manufacturing technology, this FPCBA module adopts SMT (Surface Mount Technology) circuit board encapsulation technology. It is applied to Three-Proof (waterproof, explosion-proof, fireproof) NFC smart card modules, featuring side field strength focusing, enhanced sensing distance, and the ability for electromagnetic fields to form a closed-loop circuit within slit spaces. Commonly used in identity recognition devices for military personnel, divers, and firefighters, and can be embedded in work uniforms for use.
