What is cold flow?
It is a term used when soldering with a soldering iron. It means that the solder is not completely up to temperature to make a proper joint. A good solder joint is very silvery in colour and shines when it is done right.
Can you automatically create a BBS from engineering drawings?
Creating a BBS from the Structural drawing is not at all a good practice. A BBS preparation without preparing the placing drawing will create lot of issues in fabrication, placing and steel saving.
What temperature is a soldering iron?
A soldering iron is a metal hand held probe type object heated by gas or electric for melting solder (a mixture of tin and lead). Solder is normally used for joining electrical wires and making soldered, leak proof, connections between pieces of copper pipe. It is however very hot, reaching temperatures of over 400 degrees Celsius. It is a tool (usually copper) that is heated and then applied to a joint to melt the solder and heat the metal so it will accept the solder. Some are heated by electricity some are heated in a small furnace. See "What is soldering iron" vipprogrammer.com/soldering-stations-manufacturers-36_116 it heats up your solder and makes it melt, it makes the joints in your circuit firm. it makes a little blob of solder.
Are there different types of skateboards?
Yes there are good brands of boards such as element, baker, birdhouse, active and DVS.
Is saveetha university is good for engineering?
Yes , it is . Till now without facilities . But now , rapid improvement with smart boards almost in every department , good faculty , upgrading infrastructure . A good place to learn . Its still in developmental stage .
Are printed circuit boards poisonous?
The short answer is no, but be careful anyway. The board itself is made of paper and epoxy resin which is not toxic but is not good for you. The real problem is the components on the board and the solder. All solder on older boards will contain lead, but most newer boards use lead free solder as much as possible. Electrolytic capacitors if they burst can release corrosive chemicals and many other components contain mercury, gold, silver and various heavy metals. In other words don't eat it and be sure to wash your hands after handling before you eat or smoke. There are often flame retardants that are hazardous (carcinogenic) in PC boards.
What should be prevented prior to the solder cooling in order to to get a good shiny solder joint?
Movement. The components being soldered need to be fixed, stable, and clean to allow the solder joint to solidify and adhere properly. Movement of components will cause a 'dry' joint which will be electrically unreliable and have a dull appearance.
What wattage soldering pencil should you use for soldering electric components to a PC board?
A 15 W soldering iron is pretty safe for sensitive electronic boards. I've used as large as a 30 W for larger contact points, but the 15 W is good for almost all things on a PC board. Just ground yourself and heat the point, not the solder. Also, never solder with a hot iron, use a damp sponge to cool before heating the point, then add a small amount of solder. Don't move anything after finished until the solder is cool or you will get a "cold" solder--A weaker connection.
How much solder should be applied for soldering work?
A good amount of solder is less than one drop, and should be applied through a very hot and clean gun, also making sure that you are using a new solder wire, avoid using solder from already soldered components because it will be having no zinc chloride.
Is soft solder a good conductor of electricity?
Yes: flux core solder is. No: acid core solder is not.
What is flux remover?
When circuit boards are assembled, the parts are soldered on. In order for the solder to make a good connection to the parts and to the board, a substance called flux is mixed into the solder. It removes oxidation and cleans up the surfaces of the different parts so that the solder can stick to them. After the board is assembled, there is still flux on the board. Flux remover dissolves the flux and washes it away.
Are mother boards hard to instal in a desktop?
It is quite complicated to install a motherboard. You need to have a good understanding of the components in a computer, and how they all work together.
Are tiki boards good?
No they are bad! for good boards go on a good longboard site or they will tell you the info on good boards for downhill, sliding and free ride.
What boards are good if large flat boards are needed?
errm.. large flat one are good!
Why is using much solder problematic with fine jewelry?
use the smallest amount of solder necessary to make a good joint.
Why did willam won the Battle of Hastings?
Because he is a good solder
What are the characteristic of a good solder?
must be shiny and volcano shape
