When working on PC boards or any electronic equipment, heat is the biggest enemy. A low wattage soldering iron is the best because it will generate only enough heat to melt the solder and not heat up other adjacent components that are near to the point that you are soldering. Also when working on electronic equipment use a solder with a low melting point. There is a special low temperature solder with a rosin core that is made especially for PC boards. Never use acid core solder on any electrical soldering jobs.

Copper tubing solder "Solder" is an erroneous term as solder mean lead which of course is banned (safe water drinking act) Sweating is another term for "soldering" Copper can be joined by various alloys such as 95 % tin -5% Anatomy or one of the many silver bearing types of low temperature alloys. For the strongest possible joints brazing is the best way to go with a tensile strength over 87,000 PSI compared to soft solder joints of 16,000 PSI For DWV copper joints one can use one of the lead tin solders such as 50 -50 as it is quite easy to work woth.
Solder remover is an object or device for removing solder, usually from printed circuit boards. It can be in the form of a copper mesh called solder wick, a separate vacuum device you use alongside a soldering iron, or a desoldering iron. A desoldering iron gets hot like a soldering iron, but the tip is hollow and there is a squeeze bulb mounted on top. So you heat up the solder on the board and then use the bulb to vacuum up the solder and then deposit in a safe place such as a can or ash tray.
Not cleaning the pipe or joint enough, not using flux, or not heating the pipe or joint enough. You use the blue tip of the flame on the joint and the capillary action sucks the solder into the joint. You have to clean the pipe with sandpaper or steel wool, the joints with a fitting brush on the inside, and use a proper flux and solder.
Lead free only
Rosin core solder can produce fumes containing rosin that may irritate the respiratory system if inhaled in large quantities. While rosin itself is not typically considered poisonous, it's important to use proper ventilation and safety precautions when soldering to minimize exposure to fumes.
Use lead-free solder, 0.2 percent lead or less. Lead free means NO Lead your better off with a silver bearing alloy as it has a longer pasty range or 95% tin 5% antimoney Actually the term "solder" means lead bearing according to the AWS specifications
Your question is listed in "Plumbing" but you are talking about copper wire and a lug ? IF you are asking what type of solder ? The answer would be 60/40 rosin core . Dont use acid flux or large globbs of rosin like in plumbing . How big a lug ?? General electrical, electronic low current or a big car battery terminal ??? General rule is : #1 surfaces must be clean #2 A tight PHYSICAL connection must be made first . #3 Heat the area to be soldered before soldering . Higer grade solder like 50/50 ( more tin) or Silver solder can be used for higher current applications . Lead solder tends to melt easier which is good going on but not so good if your connection is heating up .

This sounds like a challenging task. All the traces have to be reconnected and more of a task if it is a two sided board. Use a rosin core solder. The smallest diameter that you can find. Do not use acid core solder as the acid will attack the copper traces. Use a low wattage soldering iron, as high heat will de-laminate the traces from the PC board. Sometimes it is advisable to use a strand of wire from a multi strand wire to help bridge the gap of the broken board.
Yes, rosin core solder can be used with LEDs, as it provides a good electrical connection while minimizing oxidation during the soldering process. However, care must be taken to avoid overheating the LED components, as excessive heat can damage them. It's best to use a soldering iron with a fine tip and work quickly to maintain the integrity of the LED. Additionally, ensure proper soldering technique to avoid cold joints.
What to use to solder a shut off valve
You cannot solder Steel BUT you can braze steel and copper and you can thread steel and then use a copper x female adapter Or finf a steel fitting and use a C x M adapter
Solder is a method of attaching components to be electrically conductive to another component or circuit board by the melting of a lead alloy that has a rosin core. The rosin core which resembles a paste which melts to a liquid when it is heated with the lead solder that resembles as a thick wire on a spool. The rosin then flows on the conductors while the lead melts and cleans the conductors so that the lead forms easily and creates a firm bond to the conductor. Hand soldering may involve a soldering iron or a soldering gun. In a manufacturing facility the circuit board moves along on a assembly line and then briefly dipped on the bottom half of the board simultanously soldering all of the components all at once. This method is used on most electronic equipment in use today. ------------------------------------------------------------- The rosin is also used to limit oxidation of the component lead or PCB pad whilst it is being heated. Oxidation can reduce the conductivity of the solder joint.
