FPC / PCB 工程計算機

補強板 / ZIF 厚度匹配

估算 FPC、adhesive、stiffener 組合後厚度是否符合連接器規格。

補強板 / ZIF 厚度匹配怎麼用

補強板厚度常用在 ZIF、BTB、金手指或 connector 插拔區。這個工具可以檢查 FPC 本體、貼合膠與 stiffener 組合後，是否接近連接器要求厚度。

Stiffener thickness is critical for ZIF, board-to-board, gold finger and connector support areas. This calculator checks whether the assembled local thickness matches the connector requirement.

Assembled connector thickness

公式: Assembled thickness = FPC thickness + stiffener thickness + bonding adhesive thickness

FPC thickness: local flexible circuit thickness before stiffener.
Stiffener thickness: PI, FR-4, SUS or other support material thickness.
Bonding adhesive: adhesive used to attach the stiffener.
Target thickness: connector or customer-specified thickness window.

公式依據

Formula basis: arithmetic local thickness stack-up for connector insertion areas.
Engineering note: connector drawing limits, adhesive compression and stiffener material tolerance should be checked for release.

範例

0.12 mm FPC + 0.15 mm stiffener + 0.03 mm adhesive gives 0.30 mm assembled thickness.

工程注意事項

Connector drawings often define a strict insertion thickness window.
Adhesive compression and stiffener tolerance should be included for production release.
Stiffener edge should be kept away from bend areas to avoid stress concentration.

FAQ

Should adhesive thickness be counted?

Yes. The local insertion thickness includes the FPC, stiffener and bonding adhesive after lamination or bonding.

Can this tool choose the stiffener material?

Not yet. It calculates thickness. Material selection should consider stiffness, heat, cost, electrical insulation and assembly needs.
