Heavy Copper Available

Industrial Grade Flexible PCB Solutions

Built to perform in demanding industrial environments. From factory automation to power electronics, our industrial flex PCBs deliver reliable performance where durability and longevity matter most.

Industrial Flex PCB

Industrial applications demand rugged electronics that perform reliably in harsh environments for years or decades. Exposure to temperature extremes, chemical contaminants, moisture, and vibration challenges components in ways that consumer applications never experience.

Our industrial-grade flexible PCBs are engineered for these demanding conditions. Heavy copper options handle high currents required for motor drives and power conversion. Chemical-resistant materials withstand exposure to oils, solvents, and industrial fluids. Extended temperature ranges ensure operation from freezing warehouses to hot factory floors.

With decades of experience supporting industrial OEMs, we understand the importance of long product lifecycles and consistent availability. We maintain design documentation and material qualifications to support programs for 15+ years, ensuring you can count on us as a long-term partner.

Industrial Applications

Flexible PCBs enable compact, reliable solutions across industrial sectors.

Factory Automation

Robotics, conveyor systems, and automated assembly equipment use flex circuits to route power and signals through moving joints and confined spaces. Our designs handle millions of flex cycles.

Motor Drives & Power Electronics

Variable frequency drives, servo controllers, and power supplies require high-current flex circuits. Heavy copper constructions provide the current capacity needed for industrial power levels.

Industrial Controls

PLCs, HMIs, and control panels use flex circuits for compact wiring and reliable connections. Our connectors are selected for industrial durability.

Sensors & Instrumentation

Industrial sensors, measurement equipment, and monitoring systems benefit from flex PCB reliability and noise immunity. Shielded constructions are available for sensitive applications.

Energy Systems

Solar inverters, wind turbine controllers, and grid equipment use our flex circuits for reliable power and control connections in outdoor environments.

Industrial flex PCB applications

Environmental Resistance

Industrial environments present unique challenges that we address through careful material and design selection.

Chemical Resistance

Our polyimide-based constructions resist oils, fuels, and many industrial solvents. For extreme chemical exposure, specialized coverlay materials provide additional protection.

Moisture & Humidity

Industrial facilities often have high humidity or direct moisture exposure. Our materials maintain adhesion and electrical properties in humid environments up to 95% RH.

Thermal Cycling

Daily and seasonal temperature swings stress solder joints and adhesives. Our designs accommodate thermal expansion and contraction to maintain reliability.

Contamination Protection

Optional conformal coatings provide additional protection against dust, moisture, and contaminants common in industrial environments.

Power & High Current

Industrial power applications require careful attention to current capacity and thermal management.

Heavy Copper Construction

Copper weights from 2oz to 4oz provide the cross-sectional area needed for high-current traces. Our processes maintain fine features even with thick copper.

Thermal Design

Current-carrying capacity depends on heat dissipation. We analyze thermal paths and recommend design approaches that maximize current while maintaining safe operating temperatures.

Power Distribution

Bus bar flex circuits distribute power efficiently to multiple connection points. Solid copper planes minimize voltage drop in power distribution applications.

Connector Selection

Industrial connectors are chosen for current capacity, durability, and ease of maintenance. We support multiple connector families and can recommend options for your application.
