Alloy is a substance with metallic characteristics synthesized by a certain method from two or more metals and metals or non-metals. It is generally obtained by melting into a homogeneous liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloys, ternary alloys and multi-element alloys. FR-4 material will melt near 130C. Therefore, Cu Foils (produced separately) are attached to FR-4 panels using silver epoxy resins to provide reliable adhesion. Later on, after a masked exposure Cu that is not needed is etched away chemically. Commercially, Cu that etches away can be retrieved and reused.

1705, "phase of the moon, particular recurrent appearance presented by the moon (or Mercury or Venus) at a particular time," back-formed as a singular from Modern Latin phases, plural of phasis, from Greek phasis "appearance" (of a star), "phase" (of the moon), from stem of phainein "to show, to make appear" (from PIE root *bha- (1) "to shine"). Latin singular phasis was used in English from 1660 for each of the aspects of the moon. General (non-lunar) sense of "aspect, appearance, stage of development at a particular time" is attested by 1841. Meaning "temporary difficult period" (especially in reference to adolescents) is attested from 1913.

malleable metallic element, noted for its peculiar red color, tenacity, malleability, and electric conductivity, late Old English coper, from Proto-Germanic *kupar (source also of Middle Dutch koper, Old Norse koparr, Old High German kupfar), from Late Latin cuprum, contraction of Latin Cyprium (aes) "Cyprian (metal)," after Greek Kyprios "Cyprus" (see Cyprus). Ancient Greek had khalkos "ore, copper, bronze;" an old IE word for "ore, copper, bronze" is retained in Sanskrit ayah, Latin aes. Latin aes originally was "copper," but this was extended to its alloy with tin (see bronze), and as this was far more extensively used than pure copper, the word's primary sense shifted to the alloy and a new word evolved for "copper," from the Latin form of the name of the island of Cyprus, where copper was mined (the alchemists associated copper with Venus). Aes passed into Germanic (which originally did not distinguish copper from its alloys) and became English ore. In Latin, aes was the common word for "cash, coin, debt

An intriguing feature of our phase diagram version is the absence of intermetallics that are analogues of the ordered phase existing in the copper-gold system, namely, a CuPd tetragonal phase and a CuPd 3 cubic phase. In the copper-palladium system these phases are dismissed by a CuPd phase, which has another structure-building principle.
