What should the underside of a circuit board look like should the solder be flat spots or sharp points?
The solder joints should be convex and shiny.
How do you solder?
Step 1) Twist the two parts together (only do this if you are soldering two wires together).Step 2) When the soldering iron is hot enough, tin the tip of it with solder or tinning compund.Step 3) Heat the parts that are going to be joined. DO NOT MOVE THE SOLDERING IRON.Step 4) Slowly push the solder into the heated area. Sing 1 2 3 4 5 once I caught a fish alive while you are doing this. This is becuase when you finish singing it, enough solder will have melted onto the joint.Step 5) Clean the tip of the soldering iron by rubbing on a damp sponge.Step 6)Leave the solder to cool and harden.u have to use the right type of metals but for like wires u would twist the two together like _ _ not like /\ under a wire nut and use a soldering stick to heat up the exposed part of the wire and brush the solder across and it will melt on it and down into it== ==Use the soldering iron to heat both the solder pad and the parts lead at the same time. Give it a couple seconds to heat up and then apply your solder, using just enough to cover the soldering pad and connect to the wire lead. Then let the connection cool. Be sure that the part lead doesn't move during the cooling phase or you'll get what they call a cold solder joint. It takes a little practice but it's no rocket science, either.The solder should be a `rosin core` solder. What that means is that the solder has soldering flux built into it which helps clean the connection after being heat activated and also helps to ensure that the solder will flow evenly as well as adhere to the metal.A cold solder joint looks grainy and dull in appearance. A good solder joint looks shiny. If you get a cold joint, reheat it and let the solder cool down again, and if necessary, it's OK to add a touch more solder.
What is meant by tinning stranded wires?
It is a reference for the preparation for soldering a stranded wire so you get a good joint. You twist the strands together, heat the wire with a soldering iron or gun and then apply a small amount of solder on the tip of the wire and it melts into the strands. Then you can solder the wire to another like wire or to a terminal or whatever. You basically reheat the wire to make connection and can add more solder as needed.Additional informationTinning is also useful if the wire is to be put in a "screw lug". The term "tinning" comes from the fact that older solder contains lead and tin. Some of the newer solder is supposed to be lead free.
Why wont windows and wipers work on 99 escalade?
There is a contact in the ignition switch that goes bad. It also powers the radio. So the switch probably does not work when ever it feels like it. I believe the ignition switch is going bad. There is a box under the center console that has bad solder connectors. Check each connector. When you wiggle it you should get a return to function..momentarily...repair the solder joint and you should be fine.
What is the function of the flux in soldering?
Flux can be in many different forms. it can be in the solder, it can be in a soft form like butter, or it can be in a pen like a tide stain stick. it is used on the solder iron and on the thing you're soldering to make a good surface for the solder to stick to. Basically it makes soldering easier, it can be done with out it.
Is solder heterogenous or homogenous?
It could be either. Any type of liquid core solder (acid core, rosin core, etc.) is heterogenous, since there's the metal part and the core part. A solid-core solder is probably homogeneous.
How do you remove corrosion from copper pipe?
First the pipe and cap must be dry. There can be no water the pipe that will be close enough to the joint to feel the heat. You will need Soldering Flux, Solder, Emory Paper and a hot Torch. Turbo Torch is a good one, if you use MAPP Gas. Sand the pipe with the Emory Cloth until it is clean and shiny all the way around. (The width of the cloth is fine.) Sand the Cap the same way. Put Flux on the copper pipe and inside the cap. Put the Cap on the pipe, push it all the way down. Take the torch and heat the cap on it's side in one spot while holding the Solder on the opposite side at the point where the bottom of the cap and the pipe meet. When the joint is hot enough the solder will melt and start to draw into the joint. After a few more seconds remove the heat and melt solder all the way around the joint in one quick motion. You can wipe the joint with a rag if you like to make it look better before the solder hardens. Don't use Nylon or any other cloth that might melt.
Why would a blower not come on when the Lincoln Town Car 2000 and the motor was taken out and tested and works?
tbl could be with the blower motor speed controller. I had same tbl. Removed controller and remove cir. brd. from housing, and with a 10x or better mag. glass check connections on solder joints. mine had three joints with hairline cracks in solder joint. Re-solder and works like new again. better than $200.00 for a new controller..
Where can one purchase a solder station?
There are many places where one can purchase a solder station. One of the best places to purchase a solder station would be a hardware store like Lowes or Home Depot.

Where do we buy lead free solder?
Looks like somebody is selling cheap solder here; http://detroit.craigslist.org/okl/tls/3755076901.html
What is soldering?
According to Wikipedia:"Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint, the filler metal having a lower melting point than the workpiece. Soldering differs from welding in that soldering does not involve melting the work pieces. In brazing, the filler metal melts at a higher temperature, but the workpiece metal does not melt. Formerly nearly all solders contained lead, but environmental concerns have increasingly dictated use of lead-free alloys for electronics and plumbing purposes."Soldering is a process whereby two or more metal parts (wires, component leads, pipes, etc.) are joined by the melting of a metal between them. The melting metal is known as solder. Traditionally, it was usually composed of an alloy of primarily tin and lead, but due to current environmental regulations, the use of lead in solder is becoming rare. In common useage, the phrases "solder joint" and "solder connection" mean the same thing (see below), and are used interchangeably. The word "connection" by itself can refer to either a "solder connection" or to the metal parts before they have been soldered. Confused? It's gets easier when you look at how the word or phrase is used in a sentence... as follows. The soldering process requires the heating of the parts of the connection to "wetting" temperature, the temperature at which the solder will chemicaly alloy with the metal parts being soldered. This temperature is dependant upon the alloy of solder that is being used; with " traditional" alloys, it is approximately 500 degrees F. Current no-lead solders require considerably higher wetting temperatures. In either case, if "wetting" temperature is not reached, when the solder is applied to the connection, it will melt and flow onto the metal parts, but will not alloy with them, thereby causing a "cold solder joint". By the way, cold solder joints are NOT usually dull and grainey. Dull and grainey solder joints are overheated. Cold solder joints appear uneven and lumpy, and lay on the surface of the connection like water on a waxed car hood - the solder does not flow out smoothly. Depending on the application, the heat required to make the solder connection can be provided by a soldering iron, a solder gun, a torch, or a hot-air gun. Other methods exist, but are usually used only in automated processes. When a solder connection has been made properly, the connection is solid metal; there is no barrier or space between the parts of the connection. Essentially, the solder has blended with the parts of the connection, forming what is called an "interrmetallic alloy". The intermetallic alloy forms where the space between the parts was before the soldering was perforrmed. Without the formation of the intermetalic alloy, a true solder connection has not been created; what would exist would be "encapsulation" or simple "adhesion", but not a solder connection. This type of metal-to-metal connection is mechanically weak when comaperd to a solder joint, and will not provide the long term reliability and low electrical resistance that a true solder joint will provide.Soldering is a process whereby two or more metal parts (wires, component leads, pipes, etc.) are joined by the melting of a metal between them.
