Design Features

Design Features..

Successful electroplating depends in part upon the following and can be influenced by the design geometry of the component and the way it is presented by the jig to the process:

A good electrical contact between the component and the jig
Free Flow of process solution around the part
The distance of each surface of the component from the anode

The science of electroplating imposes limitations that mean and even coating on all surfaces is not possible.

What design features will improve distribution?
What features will contribute to more poor distribution?

Features that improve distribution of deposit

Rounded edges
Shallow depressions
Holes in non-critical surfaces for jig points
Drainage holes to release process solution

Features that will hinder achieving the best finish

Sharp edges and points
Deep recesses
Blind holes
Features that will retain process solutions
Jigging points left to chance may lead to marks on a significant surface
