A soldered joint used to attach a wire to the pin of a component on the rear of a printed circuit board. Spool of solder, 1. Circuit Wizard 2 Crack' title='Circuit Wizard 2 Crack' />Solder ,11 or in North America 2 is a fusible metal alloy used to create a permanent bond between metal workpieces. The word solder comes from the Middle English word soudur, via Old Frenchsolduree and soulder, from the Latinsolidare, meaning to make solid. In fact, solder must be melted in order to adhere to and connect the pieces together, so a suitable alloy for use as solder will have a lower melting point than the pieces it is intended to join. Whenever possible, the solder should also be resistant to oxidative and corrosive effects that would degrade the joint over time. Solder that is intended for use in making electrical connections between electronic components also usually has favorable electrical characteristics and must be relatively resistant to solder fatigue.

Soft solder typically has a melting point range of 9. C 1. 90 to 8. 40 F 3. K,4 and is commonly used in electronics, plumbing, and sheet metal work. Manual soldering uses a soldering iron or soldering gun. Alloys that melt between 1. C 3. 60 and 3. 70 F 4. K are the most commonly used. Soldering performed using alloys with a melting point above 4. C 8. 40 F 7. 20 K is called hard soldering, silver soldering, or brazing. In specific proportions, some alloys can become eutectic that is, their melting point is the same as their freezing point. Non eutectic alloys have markedly different solidus and liquidus temperatures, and within that range they exist as a paste of solid particles in a melt of the lower melting phase. Blue panels occurred in the TV series and are not known to have been excised by time travel. Red panels were excised by time travel. Green panels were the result of. In electrical work, if the joint is disturbed in the pasty state before it has solidified totally, a poor electrical connection may result use of eutectic solder reduces this problem. The pasty state of a non eutectic solder can be exploited in plumbing, as it allows molding of the solder during cooling, e. For electrical and electronics work, solder wire is available in a range of thicknesses for hand soldering, and with cores containing flux. It is also available as a paste or as a preformed foil shaped to match the workpiece, more suitable for mechanized mass production. Alloys of lead and tin were commonly used in the past and are still available they are particularly convenient for hand soldering. Lead free solders have been increasing in use due to regulatory requirements plus the health and environmental benefits of avoiding lead based electronic components. They are almost exclusively used today in consumer electronics. Plumbers often use bars of solder, much thicker than the wire used for electrical applications. Jewelers often use solder in thin sheets, which they cut into snippets. Lead free solderedit. Soldering copper pipes using a propane torch and lead free solder. On July 1, 2. 00. European Union. Waste Electrical and Electronic Equipment Directive WEEE and Restriction of Hazardous Substances Directive Ro. Synopsys Design Compiler. HS came into effect prohibiting the inclusion of significant quantities of lead in most consumer electronics produced in the EU. In the US, manufacturers may receive tax benefits by reducing the use of lead based solder. Lead free solders in commercial use may contain tin, copper, silver, bismuth, indium, zinc, antimony, and traces of other metals. Most lead free replacements for conventional 6. How To Program A Stanley Garage Door Remote Opener. Sn Pb solder have melting points from 5 to 2. C higher,6 though there are also solders with much lower melting points. It may be desirable to use minor modification of the solder pots e. Lead free solder may be less desirable for critical applications, such as aerospace and medical projects, because its properties are less thoroughly known. Tin Silver Copper Sn Ag Cu, or SAC solders are used by two thirds of Japanese manufacturers for reflow and wave soldering, and by about 7.

Sometimes some Dakka is not enough in those situations more Dakka is needed. More Dakka is the art of solving problems by unloading as many rounds of. Get the latest breaking news across the U.

The widespread use of this popular lead free solder alloy family is based on the reduced melting point of the Sn Ag Cu ternary eutectic behavior 2. C, which is below the 2. Sn Ag wt. eutectic of 2. C and the 5. 94. Sn Cu eutectic of 2. C recently revised by P. Snugovsky to 5. 34. Sn Cu. The ternary eutectic behavior of Sn Ag Cu and its application for electronics assembly was discovered and patented by a team of researchers from Ames Laboratory, Iowa State University, and from Sandia National Laboratories Albuquerque. Much recent research has focused on selection of 4th element additions to Sn Ag Cu to provide compatibility for the reduced cooling rate of solder sphere reflow for assembly of ball grid arrays, e. Tin Silver Copper Zinc Sn Ag Cu Zn melting range of 2. C and 1. 86. 41. Tin Silver Copper Manganese Sn Ag Cu Mn melting range of 2. C. Tin based solders readily dissolve gold, forming brittle intermetallics for Sn Pb alloys the critical concentration of gold to embrittle the joint is about 4. Indium rich solders usually indium lead are more suitable for soldering thicker gold layer as the dissolution rate of gold in indium is much slower. Tin rich solders also readily dissolve silver for soldering silver metallization or surfaces, alloys with addition of silvers are suitable tin free alloys are also a choice, though their wettability is poorer. If the soldering time is long enough to form the intermetallics, the tin surface of a joint soldered to gold is very dull. Lead soldereditTin lead Sn Pb solders, also called soft solders, are commercially available with tin concentrations between 5 and 7. The greater the tin concentration, the greater the solders tensile and shear strengths. Historically, lead has been widely believed to mitigate the formation of tin whiskers, though the precise mechanism for this is unknown. Today, many techniques are used to mitigate the problem, including changes to the annealing process heating and cooling, addition of elements like copper and nickel, and the inclusion of conformal coatings. Alloys commonly used for electrical soldering are 6. Sn Pb, which melts at 1. C 3. 70 F,1. 0 and 6. Sn Pb used principally in electricalelectronic work. C or 3. 61 F of all the tin lead alloys andthe melting point is truly a point  not a range. In the United States, lead is prohibited in solder and flux in plumbing applications for drinking water use, per the Safe Drinking Water Act SDWA. Historically, a higher proportion of lead was used, commonly 5. This had the advantage of making the alloy solidify more slowly. With the pipes being physically fitted together before soldering, the solder could be wiped over the joint to ensure water tightness. Although lead water pipes were displaced by copper when the significance of lead poisoning began to be fully appreciated, lead solder was still used until the 1. The electrochemical couple of copper and lead promotes corrosion of the lead and tin. Tin, however, is protected by insoluble oxide. Since even small amounts of lead have been found detrimental to health,1. Lead free solder. The addition of tinmore expensive than leadimproves wetting properties of the alloy lead itself has poor wetting characteristics.
