Electroless Nickel Plating with Hypophosphite
In the previous chapter, the components of electroless nickel plating baths were discussed from the viewpoint of the function each performs in the bath, with little attention paid to their effect on the plating process. The metal and the electron source (the reducing agent) are consumed in the electroless plating reaction and so their concentrations in the bath are continuously decreasing. Ther...
متن کاملElectroless Nickel Plating: Bath Control
In this paper, bath control is proposed for the electroless nickel plating through holes board process. The main parameters of the product (board) – thickness of the plating film and phosphorous content – are stabilized at constant levels using optimal tracking control. The set point for control is calculated from the model in dependence on the current state of the process. The pH-index and nic...
متن کاملData-Based Modeling of Electroless Nickel Plating
This work connects the neocybernetic theory of elastic systems to modeling of a complex industrial process. It turns out that using simple mathematics combined with multilinear tools leads to linear models that can be used for monitoring and control. As an application example, electroless nickel plating is studied.
متن کاملElectroless Nickel Plating on Magnesium Alloy
he inherent lightness and good strength-to-weight ratio of T magnesium has focused attention on increasing applications in aerospace and allied fields. Its density is two thirds that of aluminum-a conventional structure material for aerospace. Magnesium has one drawback: It is prone to atmospheric corrosion. Further, because of its high chemical affinity for aqueous solutions, it is categorized...
متن کاملCharacterization of electroless nickel plating on aluminum mirrors
Electroless nickel is often plated on the surface of aluminum mirrors to improve the ability to polish the mirror surface. Electroless nickel plating can cause a bimetallic effect, creating distortion of a mirror surface if it is heated or cooled. Published data listing the thermal coefficient of expansion and Young’s modulus as a function of temperature for electroless nickel is not readily av...
