Embodiment Construction

[0016] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, through which the purpose, features, and advantages of the present invention can be better understood.

[0017] Figure 1a and Figure 1b It is a process drawing which shows the manufacturing method of the flexible circuit board which concerns on the 1st Embodiment of this invention.

[0018] like Figure 1a and Figure 1b As shown, the manufacturing method of the flexible circuit substrate of the present invention provides that copper foil (Cu thin film) C is vapor-deposited on PI film (Poly Imide Film polyimide film) or polyester with reel to reel mode (Reel to Reel). A copper clad C-laminate film (CCL; CopperClad Laminate) 10 on a Polyester Film (S11), and a guide hole H for position sensing is provided at the edge of the copper clad C-laminate film 10 in the longitudinal direction (S12) .

[0019] The guide hole H for position sensi...

Abstract

The invention discloses a manufacture method which including the following steps: providing the first and second middle copper foil stacked film equipped with guide hole used for position sensor in the scroll-to-scroll mode respectively and performing pattern formation according to units, supplying and covering the first and the second middle covered layer film in the scroll-to-scroll mode, preparing respectively the first and the second middle FPCB; providing the first and second middle FPCB in the scroll-to-scroll mode, the upper and lower part of which provide the first and second exterior copper foil stacked film equipped with guide hole for position sensing in the scroll-to-scroll mode respectively, performing copper plating after performing partly adherence according to units and forming passed hole; covering respectively the first and the second exterior covered layer plate with opening area according to units, accomplishing the first and the second exterior FPCB.

Description

technical field [0001] The present invention relates to a method of manufacturing a flexible circuit board, and more particularly to a method of manufacturing a flexible circuit board in which an accurate position is obtained by sensing a guide hole for position sensing while utilizing a reel-to-reel method. Tracking, the pattern forming position, the bonding position of the cover layer film and the cover layer sheet, the position of the through hole or the position of the punching hole can be precisely aligned, and the lateral width of the copper foil that becomes the composition of the copper foil laminate film is limited. It has a small width, uses parallel light for exposure, and applies a glass mask with a chrome pattern to ensure a fine pattern (Fine Pattern), and relatively by reducing the error rate, ensuring reliability, and achieving integration. Minimize the number of layers of flexible circuit substrates. Background technique [0002] In general, a flexible prin...
