Abstract

An optoelectronic component includes an optical module and a host circuit board. The optical module includes a module circuit board and a gold finger that is located on a first surface of the module circuit board. The host circuit board includes a conductive elastomer corresponding to the gold finger and that is located on a first surface of the host circuit board. The module circuit board is located on the host circuit board, the first surface of the module circuit board and the first surface of the host circuit board face each other, and the gold finger is in contact with the conductive elastomer.
