Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a flexible printed circuit board. Particularly heat resistant, flexible, electrically insulating, and highly flammable, it is used as the surface of a flexible seal circuit board.
I have a 1cm screw plate similar to I for printing circuits, and polyimide 2 ilm a is sufficiently #r heat resistant, but the heat resistance of the rock layer is scary, so I put 2 and 4 treps apart. Depending on the customer's purchase or dissatisfaction, ν Rie is Ushida heat resistant, which is at most 280℃.
