How do I fix bad soldering?

If the solder refuses to flow the way you want it to:

Stop and let the joint cool.
Clean and tin your iron.
Clean off any burnt flux from the joint.
Let the iron come back up to temperature.
Then reheat the joint and try again.

Can you fix a bad solder joint copper?

Just appltying flux to the joint after its heated up and seein the solder become molten(flux acts as a cleaner).. aplying more solder(solder stick to clean copper) will solve the problem. you do not really need to pull it apart.

Can you crimp instead of solder?

Crimping offers stronger, more reliable connections than soldering. Soldering uses heated metal to join the cable to the connector. Over time, this filler metal will degrade, which may cause the connection to fail. Most electricians will agree that crimping is also easier than soldering.

Can I solder over old solder?

It must be disassembled, cleaned, fluxed, and soldered. It can not be done by just adding more solder.

What happens if you overheat solder?

If you heat the joint too long, you’ll burn the flux (it’ll smoke and turn black) and make it difficult to get the solder to flow into the joint.

What can be used in place of solder?

3 Effective Alternatives to Soldering Electronics

Heatless Soldering. I did find some buzz about a rather new method product known as electro-conductive glue.
The Twisting Fold-Over and Shrink Wrap Tubing.
The Rosin Soldering Wire “Trick”

Is there a glue for wires?

Wire Glue is an electrically conductive, water-based adhesive for use as a replacement for soldering in all types of low voltage, low current electrical connections both indoors and outdoors. Wire Glue features durability and weather protection from the elements; is chemical and oil resistant.

Are butt connectors better than solder?

At its most basic, a butt splice is a fast, effective way of connecting and securing the ends of two wires without having to solder them. While soldering has its advantages, the time and cost involved can be prohibitive. In addition, the high heat used in soldering introduces the risk of injury.

What causes solder not to stick?

A classic reason solder won’t stick to something is because you’re not getting it hot enough. My interns come to me with this problem all the time. Make sure the tip of the iron is nice and shiny. Touch some solder on it, and it should melt almost instantly.

What should I do if my guitar cable is not working?

Firmly hold one of the plug ends by the tip and sleeve, and twist off the back body housing counterclockwise. Well, Doctor, this one looks just fine.

Why is my USB plug not working properly?

Because I have to wiggle the cable around the USB end to get it working it was pretty evident that the problem was one or more broken wires within the USB plug. Hence the solution was to strip the plug apart, cut out the dodgy cable and re-solder the cable onto the plug.

What should I do if my USB plug is moulded?

There’s no point in doubling up that information. The fist thing to do is to tin the wires, making them much much easier to work with later. For those who aren’t aware tinning is applying a thin coating of solder on the outside of the wire.

What’s the best way to repair a USB plug?

The fist thing to do is to tin the wires, making them much much easier to work with later. For those who aren’t aware tinning is applying a thin coating of solder on the outside of the wire. Next we need to strip out the gunk currently on the connector, I used de-soldering wick here but use whatever de-soldering method your happy with.
