Material saves the cost of raw material.By using the equipment and the deficiency that solves the above problems of electroplating parameter in technique.
The present invention is achieved in the following ways a kind of electroplating technology of ni-based foam silver, process flow: first choice uses
Nickel target carries out PVD metallization process as metallization raw material, and to foam；Secondly by the foam tiling pressing peace after metallization
On the conductive pin of hanger, resin plate is matched with conductive pin and resin plate and hanger are to snap connection；Then hanger is hanged
It hangs on cathode rod and is placed in inside groove body, the distance between hanger and anode basket are put in anode basket between 120-150mm
The ping-pong ball that diameter is 20mm is set, silver-colored electroplating processes are carried out；Plating control is processed using grading current in carrying out silver-colored electroplating process,
Initial stage is 10-12ASD, and the time is 2 minutes, until uniformly upper plating finishes, second stage 4-5ASD, until face of achieving the goal is close
Degree；Finally the uniform silver-colored foam of plating is heat-treated, heat treatment reduction temperature control is at 750-800 DEG C.
The equipment for implementing the electroplating technology of ni-based foam silver is that anode basket is affiliated on the inner wall of groove body, and anode basket is provided with
Ping-pong ball, being equipped with anode baffle between anode basket and cathode improves coating distributing homogeneity to block anode edge effect, then positive
The edge of pole baffle and the inner wall of groove body connect, and the one side wall of the groove body is equipped with filter bag, and filter bag passes through outlet
Road is connected to filter, and the inlet duct of filter is located at groove body bottom, and hanger is located at the inside of groove body and is suspended on outside groove body
Cathode rod on, between anode basket and encapsulated copper bar be equipped with filter screen；The hanger is mainly by encapsulated copper bar, conductive pin, yin
Pole hook and resin frame composition.The hole of the filter screen is 5um.The anode baffle uses PVC material.
Copper bar is matts shaped frame, is welded conductive pin on copper bar, and in addition to being sealed on conductive pin outer copper line
Glue processing.Resin plate is connect with copper bar in buckle-type.
Beneficial effects of the present invention are that the technology process process is simple, change silver-based into technique Ni-based, are greatly saved
The cost of production；The bad problem of nickel based conductive is directed in the technique, it is conductive by common contact by improving rack design
Become needle-like conductive, significantly increases conductive uniformity.It is processed in technique of the invention using the control of ladder electroplating parameter,
Make as nickel based conductive it is bad caused by plating leakage and uneven coating problem be resolved.Production efficiency is improved, production is increased
The qualification rate of product.
