Among them, many flexible circuit boards have finger-shaped terminals as shown in FIG. 1 , and the terminals are used to contact with other connectors, so as to realize the conduction of the circuit. The terminal includes long fingers and short fingers arranged alternately, and the free ends of the long fingers protrude from the free ends of the short fingers. This terminal is the focus of the entire flexible circuit board. The existing general production method flow for this terminal is: ① firstly etch out the entire circuit; ② open a PI window at this terminal, that is, this place is not covered by the cover film; ③ surface treatment is performed on the terminal, and the terminal Attach a layer of nickel gold to protect the terminal line from oxidation; ④ Attach a reinforcing plate to the back of the corresponding part of the terminal.
此类FPC与连接器组装时，往往需要在短手指的自由端部处弯折180度地插入连接器内，而装配时经过多次插拔后端子弯折处的线路可能引起断裂，导致线路不导通，连接器与FPC不能连接上。When this type of FPC is assembled with the connector, it is often necessary to bend 180 degrees at the free end of the short finger and insert it into the connector, and the circuit at the bend of the terminal after multiple insertions during assembly may cause breakage, resulting in circuit breakage. If there is no conduction, the connector and FPC cannot be connected.
实用新型内容Utility model content
