It has been argued that firearms residue on some deceased may have come from contact with the soldiers who themselves moved some of the bodies, or that the presence of lead on the hands of one ( James Wray ) was easily explained by the fact that his occupation involved the use of lead-based solder.

In some amateur installations, the failure to use this special fitting has caused the lead in the solder to leach into the drinking water.

When the iron tip oxidises and burnt flux accumulates on it, solder no longer wets the tip, impeding heat transfer and making soldering difficult or impossible ; tips must be periodically cleaned in use.

* Brazing — Joining metals structurally by the use of a higher temperature joining alloy than solder.

When hand-soldering with non-eutectic solder 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.

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.

This may seem odd today, given the far closer solder pad spacing in use now, but in the 1970s, the heyday of the QIL, bridging of neighbouring solder pads on DIL chips was an issue at times,

This solder was a tin-lead alloy, however new solder compounds are now used to achieve compliance with the RoHS directive in the EU and US, which restricts the use of lead.

It is important to use solder compatible with both the PCB and the parts used.

For small-or medium-volume boards, flying probe and flying-grid testers use moving test heads to make contact with the copper / silver / gold / solder lands or holes to verify the electrical connectivity of the board under test.

Remnants of this effort can be seen in the form factor of the production G3: the logic board's similarity to the PC ATX motherboard standard ; solder points for a PC-type floppy drive ; and the ability to use both proprietary Apple power supplies and industry-standard ATX power supplies.

Occasionally, hoop earrings are permanently installed by the use of solder, though this poses some risks due to toxicity of metals used in soldering and the risk of burns from the heat involved.

Moreover, the Xbox 360 requires additional cooling over the factory configuration to avoid overheating issues due to the use of EEC-mandated lead-free solder, which is not capable of handling the temperature limits standard solder can.

Genesi discontinued production of the Pegasos II in 2006, as the result of new European Union legislation requiring the use of more expensive and inferior lead-free solder, imposed despite the fact that replacing normal solder delivers no environmental benefits.

Tin-lead & tin-copper alloys such as Babbitt metal have a low melting point that is ideal for use as solder, but these alloys also have ideal characteristics for plain bearings.

The lead-free packaging technology "... offers economical advantages in relation to traditional bumping processes, such as solder waste reduction, use of bulk alloys, quicker time-to-market for products and a much lower chemical usage rate.

PCB's use solder masks to prevent this from happening.

Most existing Byzantine enamels have soldered cloisons, however the use of solder to adhere the cloison wires has fallen out of favor due to its difficulty, with the exception of some " purist contemporary enamellists " who create fine watch faces and high quality very expensive jewelry.

My aim in mentioning this factor obviously is not to give license to `` wild therapy '' but rather to encourage us to use the time-honored clinical casework skills we already possess, and to use them with greater confidence, precision, and professional pride.

The purpose set forth at the beginning of this book was first to introduce the reader to a general background knowledge of the various types and capabilities of the forecasting methods already in use, so that he might then be in a position to evaluate for himself the validity of the rather astonishing empirical correlation that is to follow, and to appraise the forecast that its interpretation suggests for the future of farm prices over the years immediately ahead.

One such instance has already been presented: his use of alienation.

I cite it as evidence that he did not develop through new styles as he grew older ( as Yeats did ), but that he simply learned to use better what he already had.

In any case, anyone who fails to make significant distinction between primary and secondary applications of economic pressure would in principle already have justified that use of economic boycott as a means which broke out a few years ago or was skillfully organized by White Citizens' Councils in the entire state of Mississippi against every local Philco dealer in that state, in protest against a Philco-sponsored program over a national TV network on which was presented a drama showing, it seemed, a `` high yellow gal '' smooching with a white man.

By this time, the use of the glyph had already reached Persia, and was mentioned in Al-Khwarizmi's descriptions of Indian numerals.

Bidwill, with plans already in the works to leave St. Louis, opted instead to sign a long term lease with Arizona State University to use its Sun Devil Stadium as the home of his soon-to-be Arizona-based NFL franchise.

Another feature to make LS AAS element-specific is modulation of the primary radiation and the use of a selective amplifier that is tuned to the same modulation frequency, as already postulated by Alan Walsh.

" Previously the Nicene Creed was the only profession of faith that the Missal gave for use at Mass, except in Masses for children ; but in some countries use of the Apostles ' Creed was already permitted.

An apple, it claims, does not have the properties red or juicy, but rather observers who already believe in a concept called Red use that concept to experience an apple as red.

The saying " to pull oneself up by one's bootstraps " was already in use during the 19th century as an example of an impossible task.

The use of bricks in southern and western Germany, for example, can be traced back to traditions already described by the Roman architect Vitruvius.

The proposed encoding does not use the lexical encoding model used in the existing ISO-IR / 169 registered character set, but instead applies the Unicode and ISO character-glyph model to the Bliss-character model already adopted by BCI, since this would significantly reduce the number of needed characters.

Although the name Chordata is often attributed to William Bateson ( 1885 ), it was already in common use in by 1880.

To get all of them for the expansions up to, one can use ( in addition to the basic cases already given ) the recursion relation

For example, use of ( which gives é, Latin lower-case E with acute accent, U + 00E9 in Unicode ) in an XML document will generate an error unless the entity has already been defined.

Then in 1948, another initiative banned the use of seine nets ( devices already used by Native Americans, and refined by later settlers ) altogether.

He wrote, " The question both of our right and our power to prevent it, if necessary, by force, already obtrudes itself upon our councils, and the administration is called upon, in the performance of its duties to the nation, at least to use all the means with the competency to guard against and forfend it.

But telegraph operators were already using typewriters with QWERTY keyboards to " copy " received messages, and at the time it made more sense to build a typewriter that could generate the codes automatically, rather than making them learn to use a new input device.
