Electro Plating Engineer Interview Questions and Answers

Common defects in electroplating processes include blistering, peeling, and pitting.

• Blistering can occur due to inadequate cleaning of the substrate before plating.

• Peeling may result from poor adhesion between the substrate and the plated layer.

• Pitting can be caused by impurities in the plating solution or improper current distribution.

• Solutions include improving cleaning processes, optimizing adhesion promoters, and maintaining proper plating conditions.

• Regular monitoring an...read more

The current for plating parts is determined based on the surface area of the parts, desired plating thickness, and the type of metal being plated.

• Calculate the surface area of the parts to be plated

• Determine the desired plating thickness

• Consider the type of metal being plated and its specific plating requirements

• Use Faraday's law of electrolysis to calculate the current needed for the plating process

Coating is a general term for applying a layer of material on a surface, while electroplating specifically refers to using an electric current to deposit a thin layer of metal onto a conductive object.

• Coating can refer to various methods such as painting, spraying, or dipping, while electroplating is a specific process that involves using electricity to deposit metal ions onto a substrate.

• Electroplating provides a more uniform and controlled thickness of the coating compared ...read more

The electroplating process involves depositing a thin layer of metal onto a conductive surface using an electric current.

• Cleaning the substrate to remove any dirt or oils

• Applying a conductive coating if necessary

• Immersion in an electrolyte solution containing metal ions

• Passing an electric current through the solution to deposit metal onto the substrate

• Rinsing and drying the plated part

CD stands for compact disc, a digital optical disc data storage format.

• CD is a type of optical disc used for storing digital data.

• It was originally developed for storing and playing back audio recordings.

• CDs can also be used for storing other types of data such as software, documents, and images.

• Common types of CDs include CD-ROM, CD-R, and CD-RW.
