What should a good solder joint look like?

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.

Is soft solder a good conductor of electricity?

Soft solder is not as good a conductor of electricity as other metals like copper or silver. It has higher resistance, which means it will generate more heat and produce more energy loss when carrying an electric current. Soft solder is mainly used for joining metal parts together, not for conducting electricity.

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.

What is meant by tinning stranded wires?

Tinning stranded wires refers to the process of coating the individual strands of a wire with a thin layer of solder. This helps to improve conductivity, prevent oxidation and corrosion, and make it easier to solder the wire to other components.

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.

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.

Why do solder joints in sometypes of Orthodontic appliances like space maintainers turn black?

Solder joints in orthodontic appliances like space maintainers can turn black due to corrosion, often caused by exposure to moisture, saliva, and oral bacteria. This discoloration can result from the oxidation of metals used in the solder, especially if they contain copper or other reactive materials. Additionally, the presence of certain foods or beverages can contribute to staining. Regular maintenance and proper oral hygiene can help mitigate this issue.

Is a hinge an immovable joint?

No, a hinge is not an immovable joint. A hinge is a type of joint that allows movement in one direction, typically back and forth like a door swinging open and closed.
