In-House Design Capabilities

Uni-Flex Circuits can take your drawing or schematic and produce an interconnect solution using flexible printed circuitry. If you already have Gerber files, simply email them to us and we'll take care of the rest.

We support multiple file formats including DWG, PDF, GBR, ODB+, TGZ, and DXF, converting them into Gerber format with precision and speed.

Quality Assurance

We understand that a quality product is as important as the design itself. In-process and final inspections are performed under 30x high-powered stereo microscopes to ensure consistent quality.

All boards undergo 100% visual inspection and electrical testing per IPC standards, guaranteeing reliability and performance in every batch.

Our PCB Solutions

From single-sided flex circuits to complex rigid-flex assemblies, we deliver high-performance interconnect solutions tailored to your application.
