Structured data parsed from Wikipedia. Calendar The Maya calendrical system, in common with other Mesoamerican calendars, had its origins in the Preclassic period. However, it was the Maya that developed the calendar to its maximum sophistication, recording lunar and solar cycles, eclipses and movements of planets with great accuracy. In some cases, the Maya calculations were more accurate than equivalent calculations in the Old World; for example, the Maya solar year was calculated to greater accuracy than the Julian year. The Maya calendar was intrinsically tied to Maya ritual, and it was central to Maya religious practices. The calendar combined a non repeating Long Count with three interlocking cycles, each measuring a progressively larger period. These were the 260 day tzolkʼin, the 365 day haabʼ, and the 52 year Calendar Round, resulting from the combination of the tzolkʼin with the haab'. There were also additional calendric cycles, such as an 819 day cycle associated with the four quadrants of Maya cosmology, governed by four different aspects of the god Kʼawiil. tzolkʼin haabʼ tzolkʼin haab' The basic unit in the Maya calendar was one day, or kʼin, and 20 kʼin grouped to form a winal. The next unit, instead of being multiplied by 20, as called for by the vigesimal system, was multiplied by 18 in order to provide a rough approximation of the solar year (hence producing 360 days). This 360 day year was called a tun. Each succeeding level of multiplication followed the vigesimal system. kʼin kʼin winal tun

Solder - Intermetallics in solders

From WIKIPEDIA

Structured data parsed from Wikipedia. Intermetallics in solders Many different intermetallic compounds are formed during solidifying of solders and during their reactions with the soldered surfaces. The intermetallics form distinct phases, usually as inclusions in a ductile solid solution matrix, but also can form the matrix itself with metal inclusions or form crystalline matter with different intermetallics. Intermetallics are often hard and brittle. Finely distributed intermetallics in a ductile matrix yield a hard alloy while coarse structure gives a softer alloy. A range of intermetallics often forms between the metal and the solder, with increasing proportion of the metal; e.g. forming a structure of Cu Cu3Sn Cu6Sn5 Sn. 3 6 5 Layers of intermetallics can form between the solder and the soldered material. These layers may cause mechanical reliability weakening and brittleness, increased electrical resistance, or electromigration and formation of voids. The gold tin intermetallics layer is responsible for poor mechanical reliability of tin soldered gold plated surfaces where the gold plating did not completely dissolve in the solder. Gold and palladium readily dissolve in solders. Copper and nickel tend to form intermetallic layers during normal soldering profiles. Indium forms intermetallics as well. Indium gold intermetallics are brittle and occupy about 4 times more volume than the original gold. Bonding wires are especially susceptible to indium attack. Such intermetallic growth, together with thermal cycling, can lead to failure of the bonding wires. Copper plated with nickel and gold is often used. The thin gold layer facilitates good solderability of nickel as it protects the nickel from oxidation; the layer has to be thin enough to rapidly and completely dissolve so bare nickel is exposed to the solder. Lead tin solder layers on copper leads can form copper tin intermetallic layers; the solder alloy is then locally depleted of tin and form a lead rich layer. The Sn Cu intermetallics then can get exposed to oxidation, resulting in impaired solderability. Two processes play a role in a solder joint formation: interaction between the substrate and molten solder, and solid state growth of intermetallic compounds. The base metal dissolves in the molten solder in an amount depending on its solubility in the solder. The active constituent of the solder reacts with the base metal with a rate dependent on the solubility of the active constituents in the base metal. The solid state reactions are more complex – the formation of intermetallics can be inhibited by changing the composition of the base metal or the solder alloy, or by using a suitable barrier layer to inhibit diffusion of the metals.
