About us


All Flex was founded in August of 1991 as a quick turn prototype and low volume production manufacturer of single sided and double sided flexible circuits. The products offered today have been expanded to include etched foil flexible heaters, multi-layer flexible circuits, and extended length products. All Flex developed into a full line small to medium volume manufacturer also providing value add services like surface mount and through hole assembly, testing, design and engineering support.

All Flex focuses on responsive actions that ensure continuous quality improvements while providing attentive customer support. Our systems are designed to meet delivery and quality commitments to achieve the highest level of customer satisfaction. We also realize time is critical for our customers, therefore we strive to provide quotes, lead times, and order confirmations in 24 hours or less. We pride ourselves on quick response time.

Our staff of highly-experienced application and technical engineers are available to speak with you and share their knowledge about applying flexible products. Our technical support staff has 10+ people with over 20 years of experience in the flex and PCB industry and almost 20 with over 15 years.

All Flex manufacturers etched foil heaters fabricated using both Polyimide and Silicone Rubber as the base material. We customize with add-on components, non-traditional materials, and unique combinations to ensure the system meets the customer’s application needs.
