This industrial control PCBA solution addresses the demanding requirements of manufacturing automation, process control, and industrial IoT systems. Der 6-layer FR4 PCB (Tg≥170°C, 2.0mm Dicke) ensures robust mechanical stability and signal integrity, while the multi-layer architecture separates power and signal domains to minimize EMI—critical for high-reliability industrial environments.
