Abstract

The invention provides an ultrasonic tin plating device and a tin plating method, and relates to the technical field of electronic manufacturing. The ultrasonic tin plating device comprises a closed tin bath, an ultrasonic vibration device and a tin pump. The closed tin bath comprises a cavity and a door capable of being opened and closed, a first cavity and a second cavity are formed in the cavity, an opening is formed in the upper portion of the second cavity, the door capable of being opened and closed is arranged at the opening, the first cavity communicates with the second cavity, the tin pump is used for pumping tin liquid from the first cavity to the second cavity, and the ultrasonic vibration device is arranged in the cavity. The tin plating method comprises the steps that the tin pump pumps tin liquid in the first cavity to the second cavity, and an ultrasonic vibration device is submerged by the tin liquid; the door capable of being opened and closed is opened, a terminal is put and is put into the tin liquid; and the ultrasonic vibration device works. Due to the fact that the ultrasonic vibration device is arranged, under the condition that scaling powder is not needed, the ultrasonic tin plating device and the tin plating method can remove an oxidation film on the surface of the terminal, and the environmental protection problem caused by a conventional electroplating technology is solved.

Description

technical field [0001] The invention relates to the technical field of electronic manufacturing, in particular to an ultrasonic tinning device and a tinning method. Background technique [0002] The terminals of components need to be tinned to form a tin coating. Although electroplating technology can achieve tinning of terminals, it faces serious pollution problems and is increasingly restricted by environmental protection. [0003] An alternative technology is the hot-dip plating technology, but this technology requires immersion in flux to remove the oxide film of the terminal before immersion in tin solution for tin plating, and the extensive use of flux has environmental problems. Contents of the invention [0004] The object of the present invention is to provide an ultrasonic tinning device, which can improve the environmental protection problems caused by the existing tinning technology. [0005] Another object of the present invention is to provide a tinning met...
