AI Technical Summary

Technical Problem

The existing electroplating process for the electrode plates of flat vibration motors cannot effectively improve the hardness and wear resistance of the coating, resulting in a shortened service life of the motor under high-frequency vibration.

Method used

A nanocomposite electroplating process is adopted, in which silica with a specific surface area and particle size is added as an additive during the nickel plating process, and combined with agitation and ultrasonic dispersion, step-by-step electroplating is carried out. Finally, a gold layer is electroplated on the nickel layer surface to form a dense nickel layer to improve hardness and wear resistance.

Benefits of technology

It significantly improves the service life of flat vibration motors and extends the stability and wear resistance of motors under high-frequency vibration.

Abstract

The present application relates to the technical field of flat vibration motor accessories, and particularly relates to an electrode tab plating process of a flat vibration motor; specific specific surface area, particle size and adding amount of silicon dioxide are used as a plating aid, and a specific step-by-step nickel plating method is used for nano-composite plating; due to the addition of porous silicon dioxide particles, more nucleation centers are provided for the deposition of cathode nickel ions, the growth of nickel grains is inhibited, and the nickel layer is more compact; meanwhile, when an external force is applied to the plating layer, the silicon dioxide particles can play a pinning role in the plating layer to prevent the sliding of dislocations and the diffusion of micro-cracks. Therefore, the hardness and wear resistance of the plating layer can be significantly improved; the above method is introduced into the process of plating nickel on the tab of the PCB of the flat vibration motor, so that the service life of the flat vibration motor is improved.
