How can I choose the best solder plate?
The selection of the best soldering plate of the circuit is a process that can depend on a handful of different factors. The most important point of view is the type of soldering that you do because different techniques require specific types of solder. For example, reflow soldering or wool usually requires different materials that are fried with a soldier. However, there are some alloys that are well suitable for both applications.
In search of the best solder of the plate with circuits, the first determination you will have to make, what type of soldering you are planning. If you are molding or wave solder, you will have to look for a solder on the circuit board that lacks any flow. This is due to the fact that the flow is usually applied before application of the solder. Wool and reflow of solder is also carried out with solder paste and the presence of lead can sometimes lead to the formation of metal foam and also to potential environmental concerns.
Soldering is usually the easiest if you choose a product that has a pink core. Including flow inside the solder facilitates handling, which usually canthat help work faster. Another important factor to be considered is the alloy from which the solder is made, although any alloy of tin and lead, which contains more than 60% tin, is usually good enough for electrical work.
After you find if you need a solder on a fixed or inserting the circuit board, you will need to take into account several other factors. Although the general rule is to choose a solder that contains more than 60% tin, some applications require specific alloys. If you work with a circuit board where the solder gets into contact with traces or components of gold or silver circuits, you will have to choose a solder that is not very reactive with these metals.
The presence of tin in the solder can actually distribute gold and silver. Soldering plates of circuits that contain Indium is usually a good choice if it comes into contact with gold because Indium does not respond with goldAs it does a tin. Adding silver to the tin and lead alloy can help reduce side effects on the ingredients of silver circuits, although in these cases alloys can be used without tin.
