The invention relates to a circuit board, and especially relates to a positioning type flexible circuit board. The circuit board comprises a free end, a connecting portion, a reinforcement plate, a gold finger, a first bonding layer, a second bonding layer, a third bonding layer, a piece of conductive copper foil and an insulation substrate, wherein the free end and the connecting portion are mutually vertically connected, the connecting portion is fixedly connected with the upper end of the reinforcement plate through the first bonding layer, the reinforcement plate and the insulation substrate are fixedly connected through a second bonding layer, the insulation layer is fixedly connected with the conductive copper foil through the third bonding layer, the gold finger is arranged at the lower end of the reinforcement plate, the outer wall of the free end is fixedly connected with a positioning rod, the bottom of the positioning rod is fixedly connected with a pressure plate through a spring rod, the tail end of the positioning rod is fixedly connected with the free end through bolts, and the bottom of the pressure plate is bonded and connected to a silica gel layer. According to the positioning type flexible circuit board provided by the invention, after the gold finger is inserted, positioning and compaction can be realized, disengagement from a connector is prevented, the cost is saved, and the efficacy is improved.
