Electronic testing utilizes advanced tools and techniques to inspect product and process quality, and diagnose component failures. Reports and images can be transmitted electronically. Electronic test equipment (sometimes called 'testgear') is used to create stimulus signals and capture responses from electronic Devices Under Test (DUTs). Electronic testing also uses fault modeling and tests are generated for the assumed fault models.

Electrophoresis is the movement of an electrically charged substance under the influence of an electric field. Therefore separation by electrophoresis relies on difference in the speed of migration of ions or solutes. Electrophoretic mobility is a factor that indicates how fast a given ion or solute may move through a given medium. The electrical force acts in favor of motion and the frictional force acts against motion. Since these forces are in a steady state during electrophoresis, electrophoretic mobility is a constant for a given ion under a given set of conditions. Electrophoretic mobility is probably the most important concept to understand in electrophoresis. This is because electrophoretic mobility is a characteristic property for any given ion or solute and will always be a constant and it is the defining factor that decides migration velocities.

During electrophoretic painting, the water-diluted coating material is broken up into cations and anions. The anions are particles of the paint, while cations are amines or ammonia, with the aid of which the varnish binder is neutralized to make it water-soluble. Under the influence of direct current, negatively charged anions migrate to the positive pole (anode), where they lose their charge and thereby undergo transition into the insoluble state. Positively charged cations migrate to the negative pole (cathode) where they, too, lose their charges and change to free amines. Electrophoresis is used to apply mostly monolayer coatings of 15 to 35 µm thickness. If using electroconductive primers, it is possible to apply double-layer electrophoresis coatings of 30 to 45 µm thickness.

Electroplated grinding wheel is a metal hub with a single layer of super abrasive plated to an accurately machine rim. The wheel does not need any dressing. It is a metal disc, which withstand very high rotational speeds without bursting. Electroplated grinding wheel provides an excellent way to pre-form and cab rough. They are made of stainless steel.
