Method for isolating of FPCB has been applied to etching techniques of PCB

摘要

The present invention relates to an isorating method of a flexible circuit board, and more particularly, to form a metal routing during isorating of a flexible circuit board, and then to apply the etching technology of the printed circuit board, followed by etching and peeling to dry. It relates to an isorating method of a flexible circuit board. In the isorating method of a flexible printed circuit board according to the present invention, in the isorating method in the manufacture of a flexible printed circuit board, an etching solution is applied to the flexible printed circuit board formed with metal routing during the isorating of the flexible printed circuit board, followed by etching Disclosed is a method comprising drying under a temperature condition of ± 10 ° C.
