Record number: 1, Textual support number: 1 CONT

There are two primary methods of plating copper PCBs [printed circuit boards], panel plating and pattern plating.... Pattern plating first covers the surface with a film used to define the circuit image, so that copper is only plated on the image, not the entire surface.  3, fiche 1, Anglais, - pattern%20plating

Record number: 2, Textual support number: 1 CONT

There are two primary methods of plating copper PCBs [printed circuit boards], panel plating and pattern plating. The panel plating method plates a uniform copper thickness across the entire panel surface before the circuit image is applied, which eliminates most copper plating distribution issues. The disadvantage is that because it adds copper thickness to the surface base layer, it makes maintaining fine line definition and consistency difficult.  3, fiche 2, Anglais, - panel%20plating

davidite :... Found in pegmatites associated with quartz, biotite, ilmenite, rutile, iron and copper sulfides. Also found in hypersthene gabbro and anorthosite accompanied by scapolite, quartz, calcite, molybdenite, rutile, sphene, and tourmaline; it is obvious that the mineralization was introduced into the basic rocks by emanations from underlying granites. This is the only known occurrence of primary uranium minerals in basic rocks. One of three known primary uranium ore minerals.  2, fiche 4, Anglais, - davidite

There were two distinct types of ore at Port Radium: a high silica-gangue type pitchblende; and a carbonate barite gangue type pitchblende which also contained silver (Traill 1932).  2, fiche 5, Anglais, - silver%20pitchblende

Record number: 5, Textual support number: 2 OBS

Pitchblende is commonly associated with one or more of the primary ore minerals of iron, copper, cobalt, lead, silver, and bismuth; and the presence of these minerals in a mineral deposit is one indication of favorable conditions for pitchblende. It is usually accompanied also by bright colored secondary uranium minerals where subjected to weathering or other alteration.  3, fiche 5, Anglais, - silver%20pitchblende

An alternating current electric furnace in which the primary conductor is coiled and generates, by electromagnetic induction, a secondary current that develops heat within the metal charge.  2, fiche 6, Anglais, - induction%20furnace

Record number: 6, Textual support number: 1 CONT

There are two classifications of induction furnaces : coreless and channel. In a coreless furnace, the refractory-lined crucible is completely surrounded by a water-cooled copper coil, while in the channel furnace the coil surrounds only a small appendage of the unit, called an inductor. The term "channel" refers to the channel that the molten metal forms as a loop within the inductor. It is the metal loop that forms the secondary of the electrical circuit, with the surrounding copper coil being the primary. In a coreless furnace, the entire metal content of the crucible is the secondary.  2, fiche 6, Anglais, - induction%20furnace

Secondary sulfide zone.-In many metalliferous deposits, particularly those of copper, there is found below the zone of oxidation, a second zone containing sulfide minerals that have reprecipitated from down-trickling solutions containing metals leached from the oxidized zone. This secondary sulfide zone generally marks the change from oxidizing to reducing conditions, such as the level of ground water, at the time of secondary deposition. The zone is often greatly enriched and may constitute economically recoverable ore, whereas the original primary deposit may not.  1, fiche 7, Anglais, - secondary%20sulfide%20zone
