[0001] Interposer assembly [0002]

The present invention relates to an interposer assembly.

Generally, a board to board type connector is used to realize an electrical connection between an external device and a printed circuit board. This board-to-board type connector electrically connects a Flexible Printed Circuit Board ("FPCB") with a conductive pattern to a printed circuit board.

 A typical board-to-board connector includes a housing and a plurality of contacts (also referred to as "terminals ") fixedly disposed within the housing. Each contact is made of a conductive material, that is, a metal material. When the FPCB and the connector are coupled, each conductive pattern of the FPCB contacts the corresponding contact of the connector, and the cable and the connector are electrically connected.

As described above, the connector used for electrically connecting the FPCB to the printed circuit board has a problem in that the volume of the electronic device to which the connector is mounted is large because the connector is relatively bulky.

Further, it is necessary to arrange a plurality of contacts in the housing in a state in which a minute gap is maintained, and in the case where deformation occurs in any one of the contacts, complete electrical connection between the FPCB and the printed circuit board can not be expected.

Meanwhile, as an external cable, an interposer, which is directly mounted on a printed circuit board and electrically connected to a pattern of a printed circuit board, is developed and used without using the connector as described above.

The interposer has a plurality of terminals arranged in a matrix in the housing, and both ends of each terminal are exposed on the upper and lower surfaces of the housing. One end of the terminal exposed to the outside of the housing is electrically connected to the conductive pattern of the printed circuit board and the other end is electrically connected to the object to be electrically connected to the printed circuit board, for example, a flexible circuit board (FPC) Lt; / RTI >

When such an interposer is mounted on a printed circuit board, it is possible to fix the interposer without shaking, and to firmly and stably contact the terminal formed on the substrate constituting the interposer and the conductive pattern on the printed circuit board Means / devices are required.

On the other hand, a solder ball is used to connect the FPC cable with the interposer. That is, a solder ball is formed on a terminal of the interposer through a soldering process, and the solder ball is soldered to the contact of the FPC cable, thereby electrically connecting the interposer and the FPC cable. Therefore, since the soldering process is performed twice, there is a problem that productivity is lowered. In order to solve this problem, it is desirable to proceed the electrical connection between the terminal of the interposer and the printed circuit board and the electrical connection between the terminal of the interposer and the FPC cable without performing the soldering process.

An object of the present invention is to solve the above-mentioned problem of the interposer, and it is an object of the present invention to provide an interposer which does not require a soldering process between a connection target member and a terminal of an interposer, Assemblies. ≪ / RTI >
