This beverage dispensing machine PCBA addresses the unique requirements of food-grade automation, combining robust performance with hygiene-compliant design. А 4-слой FR4 PCB (Tg≥150°C, 1.6ММ толщина) ensures mechanical stability and signal integrity, while the multi-layer architecture separates power and signal domains to prevent interference in liquid control systems.
