AX84 - The General FAQ
Soldering with rosin core solder is cake. And the "let it flow" concept is simply to let the part you are soldering melt the solder, which ensures you get a good joint. To do this, you don't touch the solder to the tip of the iron when soldering, you touch it to the joint. Make sure you have a nice hot iron. Most folks use a 30 watt or so for everything except soldering to the chassis. I use a 230 watt squeeze trigger "gun". I never have "bad solder joints" with my gun.

Should one use solder or silver solder for joining copper tubing in fuel gas system?

Fuel Gas: Copper Fuel Gas System FAQ (Frequently Asked Quest...
Any fuel gas lines installed using copper tube must be brazed using a filler metal containing less than 0.05% P (phosphorus) and a melting temperature greater than 1000 degrees F. The only filler metal (trade and industry standard) that contains less than the 0.05% P would be an AWS BAg type alloy (according to the American Welding Society’s AWS A5.8 specification). In no case should solder or “soft-solder” be used to join copper tube and fittings in fuel gas systems.

What type of solder should I put in my solder pot?

Soldering FAQs, Soldering Basics
It is best to use the same type (alloy) of solder (in bar, or ingot form) that you will be using during the actual assembly of the pre-tinned pieces. Never put rosin-core solder (solders containing flux) in your solder pot.

What form of solder should I put in my solder pot?

Soldering FAQs, Soldering Basics
The raw solder you use should be in bar or ingot form. Bar solder melts faster with less thermal loss when cubed, and introduced in lower volumes. Be careful not to splash molten solder when you are replenishing the solder level in the pot. Never put rosin-core solder (solders containing flux) in your solder pot.

Vias and Solder Stop Mask - How Does it Work?

CadSoft Online: Frequently asked questions
EAGLE generates by default a solder stop mask for each Via (also for Pads and SMDs, of course). This means the Via is free of coating material. The solder stop mask is drawn automatically in the layers 29, tStop, for the top side and 30, bStop, for the bottom side. The size of the solder stop mask can be determined in the Design Rule's Mask settings. See the values for Stop. By default the value is fixed to 4 mils. Minimum and Maximum are set to the same values therefore.

How do I know when the solder should be changed in my solder pot?

Soldering FAQs, Soldering Basics
Because there are such a wide variety of materials and applications that a solder pot may be used for, there is no simple answer to this question. However a good general indication that it may be time to replace or clean the solder in your pot is when you experience sluggishness or degraded performance in your soldering application, while the operating temperature of the pot remains correct.

Can the tool be used to de-solder joints?

Soldering Irons, Glue Guns and Heated Seats | ColdHeat FAQ |...
Yes, using wick. Place a piece of clean wick over the joint to be de-soldered and apply the ColdHeat™ soldering tip to it. Because of the conductive nature of the wick, the tip creates heat and transfers it into the wick in a few seconds or more, depending on the size of the joint. When it appears that the soldering joint melted under the wick, remove the wick from it. If operated properly, the solder from the joint should have transferred to the wick.

What is the role of solder in a copper system?

Gutter Supply - Gutter Supplies, Gutter Machine, Gutter Mate...
In roof and wall systems where water-tight seams are required, soldering is specified. A soldered seam will join two pieces of copper or steel into a cohesive, watertight unit that will expand and contract as one piece. Well soldered seams are, in many cases, stronger than the original base material and will provide many years of satisfactory service.

What type of solder should I use?

AX84 - The General FAQ
Make sure you never use solder that says "acid core". Plumbers might use that stuff to solder oxidized metals but it will corrode the $#|+ out of your electronics if used. Avoid that stuff like the plague. Here are three types that are OK to use: Tin 37% Lead" solder is the easiest stuff to use IMO since it melts cleanly at the lowest temperature. Make sure it says "Rosin Core" if it has flux added - most have it. Then if it says "no-clean flux" it's even easier. The Kester brand works for me.

What is a good solder paste to use?

Flux Selection & Flux Residues - Foresite FAQ
Whatever works for your product. In our view, there is no such as a "good" material or a "bad" material. You just have to find materials that have the right blend of properties for your hardware and your process. We have seen very good results from: Alpha Metals UP-78, Kester 245, Indium SMQ-92J, Multicore X33, although each paste manufacturer has some excellent offerings. It depends on what you are looking for.

Is it safe to solder directly to batteries?

FAQ_Battery Packs
According to GWS security instructions of Ni-Cad and Ni-MH cells, there is a very definite instruction that you should never solder directly to the cells. The reason for this is that the cell has a number of components which are made of plastics and which can be damaged by excessive heat. In particular there is a vent designed to allow excess hydrogen to be safely removed from the cell.
