Electric Vehicle Flex Circuits

Precision flexible printed circuits engineered for the demands of EV battery management, powertrain control, and next-generation vehicle electronics.

Why GCA Flex for EV

Built for the EV Supply Chain

As electric vehicles move from niche to mainstream, the demands placed on interconnect technology have never been higher. Battery management systems require flex circuits that maintain precise electrical performance across extreme thermal cycling, vibration, and continuous mechanical flex — failure is not an option when a BMS fault can disable an entire vehicle.

GCA Flex brings 30+ years of mission-critical manufacturing discipline — developed in aerospace and defense — directly to EV applications. Our in-house fabrication in Carson, CA means full traceability, zero outsourcing risk, and DFM review on every design before tooling begins.

We hold TS 16949 automotive certification and ISO 9001:2008 — the quality infrastructure EV OEMs and Tier-1 suppliers require from their flex circuit supply chain.

Frequently Asked Questions

What flex circuit types are used in EV battery packs?
Double-sided and multilayer flex circuits are most common in EV battery management systems, providing high circuit density for cell monitoring and balancing. Rigid-flex constructions are used where the interconnect must also serve a structural function within the pack housing.
Can GCA Flex meet automotive PPAP requirements?
Yes. GCA Flex operates under a TS 16949 certified quality system, which forms the basis for PPAP documentation. Contact us early in your program so we can align our documentation process with your PPAP level requirements.
How does your DFM process work for EV programs?
Every quote includes a complimentary DFM review of your Gerber files. We flag bend radius violations, conductor width concerns for your current loads, coverlay clearances, and material compatibility for your specific thermal environment before we quote tooling or production.
Do you support prototype-to-production for EV programs?
Yes — from single engineering prototypes through full production volumes, all within our Carson CA facility. Many EV customers start with a prototype run and scale to production with zero supplier changes, maintaining consistent quality and institutional knowledge.
