FPC 疊構繪製工具：厚度、Air Gap 與孔結構

計算 FPC 疊構厚度，並繪製開蓋、Air Gap、通孔、埋孔、盲孔示意圖，可複製或另存 PNG。

疊構厚度與特徵繪圖工具怎麼用

疊構厚度與特徵繪圖是 FPC 報價、材料選擇、彎折半徑、連接器厚度與可靠度驗證的核心。這個工具可以快速加總 coverlay、adhesive、copper、PI core 與 stiffener，也能用可拖曳組件繪製開蓋、Air Gap、通孔、埋孔與可翻轉盲孔，並把疊構示意圖複製到 PPT 或工程報告。

Stack-up thickness and feature drawing are used for quotation, material selection, bend radius review, connector fit and reliability planning. This tool builds a layer-by-layer estimate with draggable assembly features for coverlay openings, air gaps, through holes, buried vias and flippable blind vias, then copies a clean stack-up diagram for PPT or engineering reports.

Zone layer sum

公式: Zone thickness = included material thickness + air-gap thickness

  • Layer thickness: nominal material thickness in mm.
  • Included layer: material counted in the current local zone.
  • Air gap: spacing retained in the geometry, but not counted as material.
  • Removed / reference layer: excluded from the local thickness calculation.
  • Assembly feature span: selected start and stop layers used to draw local features such as through, buried and blind vias.

公式依據

  • Formula basis: arithmetic stack-up thickness summation from nominal material thickness values.
  • Engineering note: lamination compression, adhesive flow and local openings should be confirmed with factory stack-up data.

範例

A 2-layer FPC can show a coverlay opening over the top layer, an air gap over the PI core, a blind via from the surface to L1, a buried via between copper layers, or a through hole across the full stack-up.

工程注意事項

  • Adhesive and coverlay thickness may change after lamination.
  • For connector areas, include stiffener and bonding adhesive in the local thickness.
  • For coverlay openings, removed layers are shown for review but excluded from the zone total.
  • For air-gap bend areas, the gap keeps geometric spacing while contributing no material thickness.
  • Dragging an assembly feature changes its board position while preserving the selected layer span.
  • Ctrl-drag duplicates an assembly feature, and double-clicking a blind via flips its stack-up direction.
  • The copy-image action exports a clean diagram without selection handles, making it suitable for PowerPoint, RFQ notes and process review documents.

FAQ

Should stiffener be included?

Include it only for local connector or support areas. Do not include stiffener when calculating a pure flex bend area.

Does lamination change the result?

Yes. The calculator gives a nominal sum. Process compression and adhesive flow should be handled with factory tolerance data.

Can this be used as an FPC stack-up drawing tool?

Yes. It is designed to calculate stack-up thickness and create a practical engineering diagram with openings, air gaps and via features.

Can the diagram be pasted into PowerPoint?

Yes. Use Copy image to place a clean PNG stack-up diagram on the clipboard, then paste it into PPT, RFQ documents or design review notes.
