Why is the L in solder silent?
The Story behind the Silent (or not so Silent) L. The word solder originates in Middle English. The Latin origin is the word solidaire, meaning to “to make solid,” which is where the -l- in solder comes from.
What is a person who solders called?
A soldier can be a conscripted or volunteer enlisted person, a non-commissioned officer, or an officer. In other words, soldiers are military personnel that participate in ground, sea, air forces, or space forces commonly known as armies, navies, air forces, and space forces respectively.
What is a solder made of?
Solder is a metal alloy usually made of tin and lead which is melted using a hot iron. The iron is heated to temperatures above 600 degrees fahrenheit which then cools to create a strong electrical bond.
Is solder a true solution?
Solder is a true solution as it is an alloy and all alloys are true solutions.
Why Lead is used in soldering?
In electronics assembly, the eutectic alloy with 63% tin and 37% lead (or 60/40, which is almost identical in melting point) has been the alloy of choice. Having the lowest possible melting point minimizes heat stress on electronic components during soldering.
Why does solder flow towards heat?
Since viscosity is the retarding force in capillary flow, this means that hot solder flows far more easily into small crevices, which yields the impression that solder flows or is drawn towards the source of heat.
Does solder run towards heat?
Also, solder will run towards the heat source, so applying solder opposite from the iron helps to spread it out and cover the joint. Lead-free solder just takes longer to “wet” the metal. Wetting is how easily and quickly solder spreads out over a surface.
Does solder flow to heat?
the simple answer is NO! The biggest problem with soldering is not applying enough heat, not using a surface cleaner (rosin or acid depending one the job), or applying too much heat. When the conditions are right, solder flows and sticks to the item being soldered.
Does solder follow heat?
You hear it over and over again, that solder or braze alloy will flow towards the heat. Another way of saying this is it flows towards hotter metal and away from colder metal.
What are the three different types of solder?
In summary, there are three main types of solder: lead-based, lead-free, and flux.
What is the difference between solder and welding?
Like many sheet metal terms, soldering and welding are used interchangeably. The main difference between welding and soldering is melting. In soldering, metal fabricators heat the metal to be bonded but never melt them. In welding, metal fabricators melt the base metal.
What is heat source in soldering?
This heat source could be a soldering iron, a hot air gun or even a butane/propane torch. The combination of mechanical strength and electrical conductivity is what makes soldering such a powerful tool for making solid connections.
What is meant by desoldering?
In electronics, desoldering is the removal of solder and components from a circuit board for troubleshooting, repair, replacement, and salvage.
What flux is used for soldering steel?
White flux is useful for brazing copper, brass, steel, stainless steel, and nickel alloys. It has an active temperature range of 1050 -1600°F (565 – 870°C).
