Why isn t my solder sticking to copper

Why isn t my solder sticking to copper

My solution is a two part, I now use a stick iron but also use my pull trigger propane torch - plug the iron in and zap it with the torch, you now have an instant-on ready to use very predictable and dependable iron - its the ticket for electronics and if you need "bigger balls" for larger mass of material melting then just zap the end and ... highly annoying soldering iron problem, solder not sticking to tip at all Hi I have now had the following problem for the hundredth time and it is getting on my nerves like nothing else: May 01, 2012 · Ah, so that's why my cos-11 wire was so hard to solder! I wasn't sure if those little strands were supposed to be stripped away or not. Had a hell of a time trying to get a solid solder joint going.

But when I've had trouble with solder not sticking to the copper it has always been because the iron isn't hot enough or the tip isn't clean enough. Sometimes I clean the hot tip in the bass shavings, then on wet paper towel or sponge because a lot of times there is some baked on brown crud that you can't see. Aug 20, 2008 · Just don't overheat the jack / PCB and melt things or cause the traces / solder pads to come off the the board. Actually if the solder pads / traces have already come off, that'd explain a lack of sticking as well -- there's nothing much left but plastic in the spot where there was supposed to be a metal lead / trace / pad. Dec 23, 2010 · Lack of the proper solder and the iron is too small for the iron wire. You need a small propane torch. Clean the wire with a fine sand paper to remove the oxidation and try to use some silver solder or brazing rod. If this is like a barb wire fence, use a twisted joint for the strength you need. Ain’t it annoying when you rip off the solder pad/copper off a flight controller (or PCB)? Fear not, you might be able to repair it! Fear not, you might be able to repair it! I pulled the RC1 and Radio 5V solder pads off my brand new Naze32 board when I was removing the pre-soldered pins .

Jun 22, 2018 · Free-form shaped suncatchers (something that isn’t round, square or any other balanced shape) can throw a bit of a curve ball if you’re still a beginner at how to solder hooks onto your stained glass. You’ll need to consider how balanced the piece is for weight. Soldering copper pipes, also known as sweating them, is a straightforward task if you do it right. If you make a mistake, however, the repair can be troublesome and time-consuming, and it's... highly annoying soldering iron problem, solder not sticking to tip at all Hi I have now had the following problem for the hundredth time and it is getting on my nerves like nothing else:

Feb 18, 2014 · I need to learn how to solder landing gear I need to solder some 1/16" music wire together to make a landing gear structure, but have no idea of how. Up till now the only thing I have ever soldered is electrical wire, and am really no expert on that. Dec 23, 2010 · Lack of the proper solder and the iron is too small for the iron wire. You need a small propane torch. Clean the wire with a fine sand paper to remove the oxidation and try to use some silver solder or brazing rod. If this is like a barb wire fence, use a twisted joint for the strength you need. If you let the solder sit on the iron, the flux quickly boils off (the fumes are from flux, not the lead). And without flux, soldering becomes almost impossible. Flux removes oxidation from metals, and it's crucial because solder won't stick to oxidized metals,... Heat and solder the tubing Leave the fitting on the copper tubing. Heat the joint with direct heat from the propane torch for about 20 seconds. When you think the joint has reached the right temperature, touch the soldering wire to the joint. The solder will melt and will be sucked into the joint between the tubing and the fitting.

1. solder only sticks to brass, copper and thin wire. 2.What kind of solder?? Acid core will stick better but has no strength at all, use silver stuff. 3.Are you using flux?? It will help the solder stick alot better. Most brake line is steel or aluminum, to which solder won't stick to. Hope that helps 2. Solder will not stick to glass alone, so each piece of glass must be wrapped in copper foil. 3. Solder needs a flux to flow smoothly and bond to other metals (i.e., copper foil or lead came). NOTE: Use only solid-core solder. Never use acid or rosin core solder for stained glass. To Solder or not to solder: Oct 1, 1997 12:00 PM, Glen Ballou. We have all heard the adage that a chain is no stronger than its weakestlink. Certainly, none of us, I hope, would stand under a 500 poundloudspeaker that is being suspended above the ground by a 1,000 pound chainwith one link of that chain’s being cut two thirds of the way through.

If solder remains on the tip of the pencil, gun or iron for any period of time, the flux boils out and must be replaced. If you find it difficult to get solder to stick on galvanized metal or any other hard-to-solder surface, add some flux (Fig. 7). This will normally improve the sticking capacity of the solder.

Nov 25, 2010 · There is no difference between soldering copper to copper and copper to brass, other than the small difference in time to heat the joint, (and there is NOT a different solder to do it), therefore you are doing something wrong, but we cannot tell you what it is from your description.

Had a hell of a time trying to get a solid solder joint going. Re: TIG Brass and Copper That would be my first choice, but its NOT a welding rod, and people on a welding forum get persnickety about that sort of terminology. Yes, phos-copper would be your best color match, and should work well.

plumbing help please. my solder wont stick! ... if its copper to copper you dont need flux. you need to make sure your copper is clean shiny for the solder to stick ...

A soldering copper is a tool with a large copper head and a long handle which is heated in a blacksmith's forge fire and used to apply heat to sheet metal for soldering.

First, you need a soldering iron that gets hot enough (but not too hot) for the conductor you are trying to solder. You also need to use a resin solder (not the same solder you'd use for plumbing). All of the surfaces need to be clean; if there is any oxidation it will not "stick". You can clean copper surfaces with steel wool. Jan 16, 2014 · I prefer to use these as my hand isn't steady enough to hold a post and solder it in place and the pads mean you can sit the fitting onto the back of the earring and it will stay put as you solder. I made holes in my solder block for the pad and post to sit in to keep them level. 2. Copper hearts just out of the pickle ready for soldering.

I pulled the RC1 and Radio 5V solder pads off my brand new Naze32 board when I was removing the pre-soldered pins . Assuming the copper pipes are cleaned to the point where the copper is totally clean and fresh quality flux designed for the solder is used in my experience over-heating is the number one cause of the solder not taking and to me that's what it looks like (although like I said without being there it's tough to know).

All the new soldering irons I see online have steel tips. I bought one. Solder isn’t sticking to it. My old iron had a copper or bronze tip which solder stuck to.

Nov 27, 2017 · There are certain things which you should do while soldering….first of all you should clean your solder iron tip regularly otherwise there will be black coating on it and the solder will fall off from the tip as a globule….. Soldering is commonly used to provide a permanent connection for copper wires, or in our industry, for sealing water or gas tight connections of piping. For many years, the soldering material used was called 60-40. This meant the metals used were 60% lead and 40% tin. This material was used primarily for copper piping used for water.
