The invention provides a displacement alignment device and method for a photodiode in an optical module, and is used for installing the photodiode in the optical module. The displacement alignment device comprises an operation connection part and an adsorption part. The operation connection part is connected with a driving mechanism. The adsorption part is connected with the operation connection part. The adsorption part has an adsorption end surface. The adsorption end surface is provided with a second positive electrode, a second negative electrode and a vacuum adsorption hole. The other endof the vacuum adsorption hole is connected with a vacuum device. The arrangement positions of the second positive electrode and the second negative electrode are matched with the arrangement positions of the first positive electrode and the first negative electrode. The second positive electrode and the second negative electrode are connected with a power supply device, and the second positive electrode and the second negative electrode are also connected with a detection device.
Description
technical field [0001] The invention relates to a displacement alignment device for a photodiode (PD), in particular to a displacement alignment device for a photodiode (PD) used for receiving light from the back of an optical module in the field of optical communication. Background technique [0002] The optical module mainly has four main components: optical transmitting component, optical receiving component, PCB, and packaging shell. Among them, the optical receiving component is used to receive the optical signal from the optical fiber, and convert the optical signal into an electrical signal to realize the signal. Receiving, therefore, light-receiving components typically include photodiodes (PDs). With the development of optical modules in the direction of higher speed and highly integrated small packages, the installation accuracy requirements of photodiodes (PDs) are getting higher and higher, and the alignment requirements of light sources and PDs are also getting ...
