FPC / PCB 工程計算機

FPC / PCB 成本估算器

依 panel 成本、製程成本、單片排版數、良率與開機費估算單片成本。

FPC / PCB 成本估算器怎麼用

成本估算是 FPC / PCB 報價前期最常用的工程工具之一。這個工具用 panel 成本、製程成本、排版數、良率、開機費與測試成本估算單片成本,適合用來比較設計方案與報價方向。

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

公式: 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.

公式依據

  • 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.

範例

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.

輸入欄位

結果輸出

  • Estimated unit cost
  • Total cost
  • Required panel count

工程注意事項

  • 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.

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.
