Flexible flat cable and manufacturing method thereof

A method of manufacturing flexible flat cable, comprising the steps of:

• forming a metal layer on an insulated base layer;
• forming a protective layer on said metal layer which had been formed above said insulated base layer, wherein said metal layer is covered between said insulated base layer and said protective layer for forming a first composite shelter;
• preparing a conducting layer and a second composite shelter, and said conducting layer composed by arranging a plurality of conducting wires in spaced-apart order;
• combining said first composite shelter, said conducting layer and said second composite shelter by a thermo-compression bonding process, and making said conducting layer be covered between said first composite shelter and said second composite shelter to form a flexible flat cable having said first composite shelter and said second composite shelter.

A method of manufacturing flexible flat cable, comprising the steps of:

• forming a metal layer on an insulated base layer by printing;
• forming an insulated glue layer on said metal layer which had been formed on said insulated base layer, wherein said metal layer is covered between said insulated base layer and said insulated glue layer to form a first composite shelter;
• preparing a second composite shelter and a conducting layer which is composed by arranging a plurality of conducting wire in spaced-apart order;
• making said insulated glue layer to face said conducting layer, and combining said first composite shelter, said conducting layer and said second composite shelter by a thermo-compression bonding process to make said conducting layer be covered between said insulated glue layer and said second composite shelter for forming a flexible flat cable having said first composite shelter and said second composite shelter.
