Single-sided flex
One copper layer for a clearly defined electrical path. Plan coverlay, terminals and the installed shape together.
Explore single-sided flex ↗POLYIMIDE PCB / FLEX PCB MANUFACTURINGFlexible circuits.
Flexible circuits.
Built around
your design.
Materials, manufacturing and practical design guidance for the connections your product depends on. Take your flex circuit from a mechanical idea to a clear fabrication brief.
01 / MANUFACTURINGThe right structure.
The right structure.
Before the first production run.
Start with the electrical connections and mechanical duty. Add layers, support and assembly requirements where the product needs them.
Double-sided & multilayer
More electrical connectivity brings more construction decisions. Define every layer and each local bend region.
Explore layer options ↗
Custom flex circuits
Connect separated components, fit a constrained enclosure and make your mechanical intent clear in the drawing.
Plan a custom circuit ↗02 / ENGINEERING FIRSTA flex PCB is more
A flex PCB is more
than a flexible board.
The material, local stackup and movement work together. Our guides connect those choices to the information a manufacturer needs.
Understand flexible PCBs ↗01↗02↗03↗
Choose a material system.
Polyimide, copper, adhesive and coverlay: compare the complete construction, not just the film name.
Define how it moves.
A bend during installation and repeated movement in service need different engineering questions.
Support the right places.
Match reinforcement to connectors, components and the transition into the flexible region.
03 / THE ENGINEER’S WORKBENCHTurn assumptions
Turn assumptions
into a clearer specification.
Work through local thickness, bend geometry and material choices. Build a project brief you can use in a manufacturing discussion.
