Overplate

Fatigue or cracking due to cyclic loading of the overplate is influenced by its thickness.

Although a minimum 30 micro-inch Au layer is the normal connector contact overplate thickness, a 30 micro-inch layer of nickel-palladium (Ni/Pd) with a Au flash has been reported resistant to both and hydrogen BGA

The next phase is to adapt a wax sheet to fit against the vertical flange of the stage, so forming an overplate.

The once near-surface rocks will be relatively more oxidised, so that the fluids will tend to oxidise the overplate and, consequently will not precipitate silica but rather dissolve it.

Pits in the nickel plate were introduced by accelerated corrosion testing and the casting was overplated with copper before sectioning.

The mesenchymal or cell-matrix tissue can be constituted with smooth muscle cells and overplated with endothelial cells to simulate the wall of an arterial vessel.

Obviously, it does little good to meet the tolerance of the +0.005 inch, only to overplate the holes with lesser tolerance.

If there is free iron on the surface, copper will overplate onto iron.

Reflectance spectroscopy (Roush and others, 1993) suggests Mars has a dominantly basaltic crust, but this result may apply only to the surficial rocks, which could be overplated basalt (Lowman, 1989).

...which may have overplated the Archean continents in response to the widespread rifting characteristics of this time of the Earth's history.

A comparison is shown in figure 1 where it can be seen that with positive photoresist (top) the solder is overplated and with thick negative photoresist (bottom) the solder remains in the photresist pattern.
