Depends on the solder used. If silver solder is used it is actually stronger than the pipe itself.

What precautions should be observed when handling a MOSFET?

Mosfets should be protected from static electricity. Handle with anti static protection. Use solder-wicks when desoldering as solder-suckers create enough static electricity to damage mosfets. Also susceptible to over voltage. A mosfet will break if a short cuircuit happens thru it and blow other paralleled mosfets too.


How do you isolate fault in a open resistor?

You need to first understand the way the resistor is "put together". There are various different types, and you didn't specify. For example, there are simple bulk resistors where everything in the electrical path lies on a straight line. In a wirewound resistor, the resistor element is wound in a spiral around a cylinder. Or you could be talking about a resistor in an Integrated Circuit (IC) or on a thick-film hybrid circuit. You could be talking about a small "chip" resistor that goes onto a PCB. You need to be more specific to get a more specific answer.The first thing you should determine is if the resistor is actually open, or if you simply have a bad connection to the resistor. Is it soldered to something? If so, use an ohmmeter equipped with pointed probes to check for connection on either side of both of the resistor's solder joints, if possible. If this is not possible (such as in the case of a surface mount "chip" resistor), you have to consider the solder joint as part of the resistor in the investigation.In fact, you should keep in mind that failure of a solder joint is MUCH more likely than simple failure of a resistor, unless the resistor has had too much current passed through it. Resistors tend to be mechanically more robust and reliable than solder joints.If the resistor was electrically overstressed (too much current, causing too much power dissipation/heat) the point of failure should be fairly obvious. There will be black, carbonized material at the failure point. You may need an optical microscope to see it, and it could be internal. There may be other external signs, such as bulging or discoloration that are not as obvious.If the resistor is not truly open but merely very high resistance, it may be possible to thermally image the fault location. Care must be taken to not pass through too much current and make the fault worse (unless you only care about the fault's location and not its cause).A high resolution x-ray can be used to image and find electrical opens in some types of resistors. It may also be possible to use more advanced tools such as Acoustic Tomagraphy, but that is rarely justified for using on a resistor that has become open. There are simpler, cheaper techniques that will give good results. The big advantages to x-ray and Acoustic Tomagraphy are that they can be done non-destructively.If it is a true electrical open, you generally expose the conductive element by stripping off the exterior chemically, or by cross-sectioning the device. Opens can then usually be spotted with simple optical microscopy. If the defect is too small, a Scanning Electron Microscope (SEM) can be used to image it. If one lead of the resistor is grounded, the un-grounded part of the resistor will quickly accumulate a charge and start to "glow" in the SEM, exposing the site of the open.Remember, if you couldn't verify that the solder connections to the resistor were OK, you have to consider them as possible points of failure in the analysis.


Why would electricity go off if too many appliances are running?

Circuit breakers are in place to prevent an over-current condition. When too much current is passed through a wire, it overheats and can result in fire. The circuit breaker is just doing its job when it turns off a circuit in that kind of condition. Too many appliances running simply means too much current on a circuit.

Do soldered joints have too high a resistance?

Soldered joints will have a higher resistance if the joint is not a clean solder joint. Badly soldered joints are classed as a cold solder joint. <<>> ...for what? Application matters here.


What are the six types of bad solder connections?

Cold solder joint: occurs when the joint doesn't fully melt, leading to poor electrical conductivity. Insufficient solder: not enough solder used, resulting in weak or incomplete bonds. Excessive solder: too much solder applied, causing bridging or short circuits. Solder balling: result of excess solder that forms into small balls. Solder splashes: occurs when excess solder splashes onto nearby components. Solder flux residue: leftover residue from flux can lead to corrosion or poor connections over time.

How do you remove and replace CV joints on a 1993 Plymouth Voyager?

Don't bother replacing the joints, replace the axles. The cost isn't much different and your getting new joints and boots, not to mention less time to do it. Check for weak motor mounts on this van, they contibute to axles popping out if they are too weak. Alignment of where the motor sets is critical.


What is a solder splatter?

Solder splatter refers to small droplets or fragments of solder that can be scattered during the soldering process. This can happen when using too much solder or when the soldering iron is moved too quickly or forcefully. Solder splatter can cause short circuits or damage to surrounding components if not cleaned up properly.


What type of solder to use to solder charms to a silver charm bracelet?

Silver jewelry requires that you use silver solder for repairs. It is silver based where common solder is lead or tin based. Standard solder is too acidic and will corrode the jewelry. It can probably be found on e-bay. Or ask a jeweler where he or she gets it.


What causes dry joints to occur?

Dry joints can occur due to insufficient soldering during the assembly process, leading to poor electrical connections. Other causes can include excessive heat during soldering, contamination on the soldering surface, or using the wrong type of solder alloy. Dry joints can lead to unreliable connections, increased resistance, and eventual failure of the electronic component.


What element is in solder?

Solder can be configured with several different types of metals. For instance, silver solder would contain a portion of silver along with another metal. Common electrical solder usually contains a mixture of tin and lead in the ratio of 60/40. That too can vary if the manufacturer wants to make a solder that requires a higher tempreature to melt it.


How do you repair a 1994 gmc sierra 1500 wiper motor?

You Don`t You Replace It. Are you sure its not the circuit board that is your problem. Some GM trucks had a recall on the wipers because the circuit board had a fracture on one of the main solder joints. Super easy to fix. Just pull off the cover of the wiper gear/motor/circuit box and take a real close look at the large solder joints. Use a magnifying glass if you have too. Then just bust out the soldering gun, touch up the fracture(small crack) and your golden.
