Is it OK to solder AC wires?

Soldered connections are acceptable, with a few caveats… All connections must be insulated to the degree offered by the wire jacket.

How do you solder wire to PCB?





You attach wires to printed circuit boards (PCB) in a process called soldering. You heat the wire and PCB pad, melting the solder wire and allowing it to flow onto the wire and pad. The solder wire used is typically a lead-tin alloy although in some special cases, silver is used.

Should you solder 120V connections?

Re: soldering 120V stranded wire



Crimped connectors are designed to be used without solder. If you want to take a well engineered solution and make it far less reliable, then go ahead and solder it.

How do you connect wires to a circuit board?

Quote from the video:
Quote from Youtube video: First heat up the wire add the little solder. And hold your soldering iron until the solder melts on top of the wire. Then move the soldering iron slowly.

Why is soldering going to be illegal?

Legislative History. In 1986 Congress Amended the Safe Drinking Water Act, prohibiting the use of pipes, solder or flux that were not “lead free” in public water systems or plumbing in facilities providing water for human consumption.

Will solder carry current?





When the molten solder cools, it hardens and creates a nearly unbreakable bond that will conduct electricity.

How do you solder wire to a pad?

A solution that I share is to pretin both the pad and the wire with the solder, using a flux. To pretin the wire, I suggest melting some of the solder in a crucible or solder pot. Dip the wire in the flux and then into the molten solder. A teardrop should form on the end of the wire.

Which solder is best for circuit boards?

How do you solder wires to terminals?



Quote from the video:
Quote from Youtube video: We'll start by touching the solder between the wire and the cup to form a heat bridge. Then we'll move the solder wire over to the center of the cup to avoid touching the left or right edges.

How do I attach wires to a circuit board without soldering?

What you need: a roll of electrical tape and two wires whose ends have been twisted together. First, lay the twisted part of the wires onto a strip of electrical tape. Wrap the tape around the wires tightly 5-6 times, making sure to cover up all the wire. Give your connection a tug to make sure it is strong.

What type of soldering iron should I use for electronics?

What Type of Soldering Iron Should I Use for Electronics. A pencil type is an ideal soldering iron for small electronics or more detailed soldering applications like circuit boards.

Can you damage a circuit board with a soldering iron?



Burns happen when the iron is too hot. Unmasked boards seem more vulnerable than solder masked boards. Loosened traces/pads and solder mask damage happen when you apply too much force with the soldering iron (trying to get that stubborn lead loose). Warping of the PCB is possible but you have to try hard.

Can I use Vaseline as flux?

Can You Use Vaseline as Flux? Yes, Vaseline works just as well as commercial flux, and you can even buy a generic brand. Petroleum jelly is primarily made from waxes and mineral oils so that it won’t corrode your components. Plus, it cleans away the gunk and eliminates metal oxides that could compromise your bond.

Do I need flux to solder electronics?

When soldering an electronic connector to a contact point (often called a “pad”), you generally need the following: A soldering iron capable of reaching the melting point of the solder. Wire solder, with or without a flux core. Flux, if the wire solder does not include a flux core or if additional flux is needed.

What can I use if I don’t have soldering flux?

Petroleum jelly is the best effective alternative to commercial flux. Its waxes and mineral water ingredients make it antioxidant thas why you can easily use it as a soldering flux.

Is soldering paste the same as flux?



Solder paste flux is different than liquid flux in both physical form and activity level. Solder paste flux typically contains 60-80% by weight active ingredients, compared with liquid flux’s 2-25%. By weight, a mixed solder paste commonly consists of 90% metal.

Is silver solder good for electronics?

Great for a wide variety of electronic soldering applications. TrakPower Rosin Core Silver Solder is the perfect choice for creating strong solder joints with low resistance and high conductivity. It is safe for the environment and is RoHs compliant, containing no lead and only 3% silver.

Can you use acid core solder for electronics?

Please be advised that acid core solder is NOT recommended for electrical or electronic soldering applications due to the corrosive nature of the residue. Acid Core wire is available in most tin/lead alloys as well as lead-free alloys.

Is silver solder better than lead solder?

Silver solder usually refers to a stronger solder used for mechanical joins (compared to lead solder which is soft and relatively weak). However, silver solder has a higher melting temperature, which means the parts have to be heated to a higher temperature to make it work.
