Patent ID: 8853547

Claim:
A flexible printed circuit board comprising: a flexible carrier layer that includes electrically conductive strip conductors running therealong; plural bonding surfaces that are arranged on a bonding side of said carrier layer, and that are electrically connected to said strip conductors; plural outwardly exposed soldering surfaces that are arranged on a solder side of said carrier layer opposite said bonding side, and that are electrically connected to said strip conductors whereby said strip conductors electrically connect said soldering surfaces with said bonding surfaces; and a stiffening plate that is inseparably connected to said carrier layer on said solder side thereof; wherein said flexible printed circuit board has plural holes penetrating through said soldering surfaces and said carrier layer, said holes are respectively concentrically positioned in said soldering surfaces, each respective one of said soldering surfaces is larger than and extends as a rim around a respective one of said holes and said soldering surfaces are confined to said solder side of said carrier layer and do not penetrate into said holes in said carrier layer.
