FPC / PCB Engineering Calculator

FPC / PCB Cost Estimator

Estimate unit cost from panel cost, process cost, pieces per panel, yield and setup charge.

How to use the FPC / PCB Cost Estimator

Cost estimation is useful during early quotation and design tradeoff review. This calculator estimates unit cost from panel cost, process cost, pieces per panel, yield, setup charge and test cost.

Panel-based unit cost estimate

Formula: Unit cost = (required panels x panel cost + setup cost + quantity x test cost) / good quantity

  • Required panels: good quantity divided by effective good pieces per panel.
  • Panel cost: material cost plus process cost per panel.
  • Yield: estimated good percentage after manufacturing and inspection.
  • Setup cost: fixed charge spread across the order quantity.

Formula Basis

  • Formula basis: panel-based manufacturing cost allocation model.
  • Engineering note: final quotation can include tooling, minimum charges, scrap rules, surface finish, lead time and commercial margin.

Example

For 1000 pcs, 20 pcs per panel, 90% yield, 200 cost per panel and 2000 setup cost, the estimated unit cost is driven heavily by yield and setup allocation.

Inputs

  • Good quantity
  • Pieces per panel
  • Estimated yield
  • Material cost
  • Process cost
  • Setup cost
  • Test cost

Outputs

  • Estimated unit cost
  • Total cost
  • Required panel count
  • Good units per panel

Engineering Notes

  • Small quantity orders are strongly affected by setup cost.
  • Panel utilization, yield and surface finish can change unit cost more than material thickness alone.
  • Use this as a quotation model; actual factory pricing may include minimum charge, tooling, shipping and margin.

Validation Checks

  • Panel utilization
  • Yield sensitivity
  • Setup cost allocation
  • Quotation comparison

FAQ

Is this a final quotation?

No. It is an engineering estimate for comparison. Final quotation depends on factory pricing rules, tooling, material purchase, lead time and commercial terms.

Why include yield?

Yield directly changes how many panels must be produced to deliver the requested good quantity.
