发明实施例提供另一种八通道高速率光接收器件，在上述实施例的基础上，针对软板9做了改进，由于软板9的材质原因与壳体1之间无法做到紧密贴合，导致该光接收器件的气密性不够好，因此在该八通道高速率光接收器件中增加了陶瓷连接块，用于连接在第一跨组放大器81、第二跨组放大器82和软板9的焊盘之间；陶瓷连接块位于壳体1外部的一端与软板9的焊盘电连接，陶瓷连接块位于壳体1内部的一端分别与第一跨阻放大器芯片81和第二跨阻放大器芯片82电连接。该陶瓷连接块能够与壳体1紧密贴合，保证了该八通道高速率光接收器件的气密性。The embodiment of the invention provides another eight-channel high-speed optical receiving device. On the basis of the above embodiment, improvements are made to the soft board 9. Due to the material of the soft board 9, it is impossible to fit tightly with the housing 1, resulting in the poor airtightness of the optical receiving device. Therefore, a ceramic connection block is added to the eight-channel high-speed optical receiving device, which is used to connect between the first cross-group amplifier 81, the second cross-group amplifier 82 and the pads of the soft board 9; one end of the ceramic connection block located outside the housing 1 is electrically connected to the pad of the soft board 9, and one end of the ceramic connection block located inside the housing 1 is electrically connected to the first transimpedance amplifier chip 81 and the second transimpedance amplifier chip 82. The ceramic connection block can fit tightly with the housing 1, ensuring the airtightness of the eight-channel high-speed optical receiving device.
这里，陶瓷连接块与软板9的镀金焊盘通过焊锡连接，陶瓷连接块分别与第一跨阻放大器芯片81和第二跨阻放大器芯片82通过金线电连接，通过采用金线连接的方式实现了高速互联。Here, the ceramic connection block is connected to the gold-plated pad of the flexible board 9 by soldering, and the ceramic connection block is electrically connected to the first transimpedance amplifier chip 81 and the second transimpedance amplifier chip 82 by gold wires, thereby achieving high-speed interconnection.
