摘要
通过对比外壳镀液性能,可以得出结论,镀液性能主要体现在镀层的附着力、流淌性与耐蚀力等方面,其中Ni–P合金形成的镀液稳定性比较理想,同时成本低、镀速高,因此应用范围比较广,但在使用时对加热设备具有较高的要求,如果设备达不到标准,就会直接影响镀层性能。另外,当厚度达到一定标准后,与Ni–B镀层相比,采用Ni–P镀层,可以让粗糙度降低,同时提高其附着力,但焊料流淌性通常会受到影响。当镀层厚度增大,镀层性能也会随之发生改变,这将成为研究的重点。
By comparing the performance of the shell plating solution,it can be concluded that the performance of the plating solution is mainly reflected in the adhesion,fluidity and corrosion resistance of the coating,among which the stability of the plating solution formed by Ni–P alloy is ideal,the cost is low,the plating speed is high and the application range is wide.However,the heating equipment has higher requirements in use.If the equipment does not meet the standard,the coating performance will be directly affected.In addition,when the thickness reaches a certain standard,compared with Ni–B coating,Ni–P coating can reduce the roughness and improve the adhesion,but the solder fluidity is usually affected.When the thickness of the coating increases,the performance of the coating will also change,which will become the focus of research.
