Take you to understand what is the FPC upper and lower connection, FPC connector circuit issues

FPC connectors are mainly used in various digital communication products, portable electronic products, computer peripherals, measuring instruments, automotive electronics and other fields, such as mobile phones, digital cameras, notebook computers, MID, MP3/4/5, handheld games, audio systems, etc. If the black pull rod is on the lower part and the golden finger is on the upper part, it mainly depends on whether the contact surface between the connector and the golden finger is on the upper part or on the lower part. If it is on the upper part, it is on the upper part, and if it is on the lower part, it is on the lower part. The common clamshell is generally on the lower part. At present, there is a double-sided connection of the front insertion and rear lifting type, that is, there are points on both the upper and lower parts. Can play the role of contact.

In the circuit board of the connector, the 1、 is used for laminating two layers of single-sided PI copper clad laminate materials with the aid of the bonding adhesive windowed at a specific position, and then the opposite conductor circuit board of the two-layer separation structure in the local area is used to achieve the circuit board with high warpage performance in the layering area, which is called the substrate generating double-sided board. In 2、 FPC connector, for the double-sided circuit board, it mainly uses the double-sided PI board copper-clad plate material to complete the double-sided circuit, and then adds a layer of protective film on both sides respectively, so as to form a circuit board with double-layer conductors. The 3、 FPC connector is also provided with a substrate generation single panel, which uses pure copper foil material in the circuit manufacturing process, and then respectively adds a layer of protective film on both sides, so as to manufacture a circuit board with only a single layer of conductors, but conductors are exposed on both sides of the circuit board, so the circuit board is called a substrate generation single panel. 4、 that the single panel in the connector is made of single-sided PI copper. After the circuit is completed, it will be covered with a layer of protective film, and then a flexible circuit board with only a single conductor of the connector will be formed.
