A working calculator for PCB designers and electronic engineers. See exactly how material, stackup, copper weight, size and quantity move the price of a flexible circuit — then send your files to PCBSync for an exact quote.
Reference estimate only. Real flex pricing depends on your gerbers, bend requirements, tolerances and current capacity. For a binding price, send your files to PCBSync below.
Flex pricing is built from a handful of parameters. Knowing which ones dominate lets you design to a target cost instead of discovering it at quote time.
The single biggest lever. Each added conductive layer means more imaging, lamination and drilling steps — and lower yield. Going 2→4 layers can roughly double per-unit cost.
Polyimide is the workhorse for performance and temperature. PET cuts material cost but limits assembly. The substrate sets your floor price before any features are added.
You pay for the panel space your part occupies. Larger boards and odd outlines waste material and reduce the number of parts per panel, pushing unit cost up.
Heavier copper (2 oz+) carries more current but etches slower and stresses the bend. It's a modest adder on its own but compounds with fine-line tolerances.
Hard gold for connectors, impedance control with TDR coupons, EMI shielding and stiffeners each add tooling and per-unit cost. Spec only what the design truly needs.
Tooling (NRE) is one-time, so per-unit cost falls fast as volume rises and panels fill out. The gap between 10 and 1,000 pieces is often 5–10× on unit price.
The base film and copper foil you choose set the baseline before features. Here's how the common flex materials compare on cost and where each fits.
| Material | Rel. cost | Max temp | Best for | Watch-outs |
|---|---|---|---|---|
| Polyimide (Kapton) | Baseline | ~260 °C | Most flex circuits; solderable, dynamic bending, high reliability | Higher film cost than PET; absorbs moisture if unbaked |
| PET (polyester) | −20–30% | ~105 °C | Low-cost membrane circuits, single-layer, no reflow assembly | Cannot survive solder reflow; limited layer count |
| PEN | −10–15% | ~160 °C | Cost-down alternative where moderate temperature is acceptable | Narrower supplier base than polyimide |
| Rolled-annealed (RA) copper | Standard | — | Dynamic flex — survives repeated bending and folding | Costs more than ED copper; longer lead |
| Electrodeposited (ED) copper | Lower | — | Static / one-time bend applications | Less fatigue resistance than RA in dynamic flex |
| Adhesiveless laminate | Premium | — | Fine-line, high-reliability and high-temp builds | Higher laminate price; needed for tight pitch |
Layer count drives processing steps and yield more than any other parameter. Relative cost below is normalized to a single-layer build of the same size.
Single-sided flex. Jumpers, simple interconnects, LED strips and membrane circuits.
Relative unit cost1.0×Double-sided with plated through-holes. The most common flex build for routing density.
Relative unit cost1.8×Multilayer flex or rigid-flex cores. Controlled impedance, power and ground planes.
Relative unit cost3.6×High-density and rigid-flex assemblies for compact, high-speed designs.
Relative unit cost5.6×Most of a flex part's cost is locked in at design. These moves cut price without quietly hurting reliability.
Re-route to fit fewer conductive layers before reaching for a 4-layer stack. It's the highest-leverage saving available.
Design a part that arrays cleanly on a panel. Tight nesting raises parts-per-panel and lowers material cost per piece.
Use OSP or immersion silver for general pads; reserve hard gold for edge connectors and contact areas that actually wear.
Add FR4 or steel stiffeners only under connectors and component zones — not across the whole part.
Tight line/space and registration drive yield loss. Hold tolerances only where the circuit truly requires them.
Tooling is one-time. Consolidating builds and ordering at volume spreads NRE and fills the panel.
The estimate above gets you in the ballpark. Send your gerbers and stackup to PCBSync for a binding price, DFM feedback and lead time on your flexible circuit.
