A reverse mask is then applied (Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces). Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight. Tin-lead or other surface platings are then applied.
Electrogalvanization. Electrogalvanizing is a process in which a layer of zinc is bonded to steel in order to protect against corrosion. The process involves electroplating, running a current of electricity through a saline/zinc solution with a zinc anode and steel conductor. Such Zinc electroplating or Zinc alloy electroplating maintains a ...
Boilerplate text. Boilerplate text, or simply boilerplate, is any written text ( copy) that can be reused in new contexts or applications without significant changes to the original. The term is used about statements, contracts, and source code, and is often used in the media pejoratively to refer to clichéd or unoriginal writing.
Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...

Copper electroplating is the process of electroplating a layer of copper onto the surface of a metal object. Copper is used both as a standalone coating and as an undercoat onto which other metals are subsequently plated. [1] The copper layer can be decorative, provide corrosion resistance, increase electrical and thermal conductivity, or ...
Music engraving. Sample of hand-copied music manuscript, in ink, of a piece composed for piano. Music engraving is the art of drawing music notation at high quality for the purpose of mechanical reproduction. The term music copying is almost equivalent—though music engraving implies a higher degree of skill and quality, usually for publication.
