FPC / PCB 工程計算機

PCB 拼版排版計算器：利用率、行列數與旋轉排版

依 panel 尺寸、單片尺寸、間距與板邊，估算 PCB / FPC 排版數量、行列數、旋轉排版與材料利用率。

排版利用率計算器怎麼用

排版利用率直接影響材料成本、製程良率與報價。這個工具用工作片尺寸、單片尺寸、間距與板邊估算可排片數與材料利用率。

PCB panelization and panel utilization directly affect material cost, process yield and quotation. This tool estimates piece count and utilization from panel size, unit size, gap and edge rail.

Rectangular panel array

公式: Count = floor((usable width + gap) / (unit width + gap)) x floor((usable height + gap) / (unit height + gap))

  • Usable width: panel width minus edge rails.
  • Unit size: single part size including required outline allowance.
  • Gap: spacing between units.

公式依據

  • Formula basis: rectangular array arithmetic using usable panel size, unit size and spacing.
  • Formula basis: PCB panelization count is evaluated in both normal and rotated orientation, then the higher usable count is reported.
  • Engineering note: tooling holes, fiducials, coupons, grain direction and factory panel standards can reduce usable area.

範例

A 250 x 350 mm panel with 45 x 70 mm units, 3 mm gap and 10 mm rails fits the best rectangular count shown by the tool.

結果輸出

  • Best piece count
  • Rows and columns
  • Material utilization
  • Rotation choice

工程注意事項

  • FPC panelization may also need tooling holes, stiffener placement, coverlay alignment and test coupons.
  • Rectangular utilization is a first estimate; irregular nesting can improve special shapes.
  • High utilization is not always best if it harms yield or handling stability.

FAQ

Does this support irregular FPC shapes?

Not yet. It gives a rectangular estimate. Irregular nesting can be a later premium tool.

Should coupons be included?

For production costing, reserve space for coupons, tooling holes, marks and handling rails.
