Can I solder with water in the pipe?

Can I solder with water in the pipe?

Don’t try to solder pipes with water in them. Soldering a joint in pipes that contain even tiny amounts of water is nearly impossible. Most of the heat from the torch goes into turning the water to steam, so the copper won’t get hot enough to melt the solder. Stop the trickle of water with a pipe plug.

How do you know if your solder joint is good?

A good solder joint should have an even band of solder showing all the way around. If you see an area that looks as if it needs more solder, brush a little flux onto the joint. If the joint is still warm, the flux will melt and flow into the void. Then reheat the joint and resolder.

Does rosin flux need to be cleaned?

Yes, rosin flux should be cleaned off of a printed circuit board (PCB) after soldering is completed.

Can I clean PCB with alcohol?

Isopropyl alcohol is a great PCB cleaner because it is inexpensive and evaporates quickly. Compared to other cleaners used for similar purposes, alcohol contains fewer chemicals. It is important that isopropyl alcohol used to clean your circuit board is 90% or better.

How do you use flux remover?

To absorb the flux residues, a lint-free poly-cellulose wiper can be placed over the repair area, and the spraying and scrubbing can occur over the material. Then remove the wipe and brush attachment, and spray over the board for the final rinse.

What can I use to clean my solder flux?

Isopropyl alcohol is the most common solvent used for removing flux, but Techspray offers flux removers that can do the job more effectively and efficiently. One common way to clean flux is the wet a swab with isopropyl alcohol and wipe around the solder joint.

Do you need to clean flux?

Yes, flux should be cleaned off of a printed circuit board (PCB) after soldering is completed.

How do you remove no clean flux residue?

In order to effectively clean and remove no clean solder pastes and no clean flux residues, a polar solvent or a solution of water and saponifier is necessary. Most no clean pastes require an organic saponifier for effective flux removal, but some can be cleaned with inorganic saponifiers.
