Powering Motors and Motion
Industrial drive PCBs sit in servo amplifiers, frequency inverters, and motor controllers. They convert logic-level commands into power output. Boyastar builds Industrial Drive PCBs that handle the dual demands of high-voltage isolation and high-current conduction.
Two worlds on one board. The logic side runs at 3.3V or 5V. The power side handles 300V DC bus or higher. These two sides cannot mix. Our Industrial Drive PCBs use distinct isolation zones. We provide sufficient creepage and clearance distances between high-voltage and low-voltage sections. Solder mask coverage is checked to ensure no contamination creates leakage paths. Gate drive signals cross the isolation boundary with proper clearances-we route these with care to avoid coupling noise into the logic section.
Current capacity is non-negotiable. Motor phases can draw tens of amps. Our boards support copper thickness up to 6 oz. We use wide traces on outer layers and multiple vias to connect power components. Thermal vias under IGBTs and MOSFETs help conduct heat to ground planes. Each board is tested for high-potential isolation and low resistance on power paths. Boyastar has been producing PCBs for 18 years. Monthly capacity exceeds 50,000 square meters. IATF 16949 and UL certifications cover our processes.
