What is soldering?
The term soldering means a method of permanently connecting two or more contacting parts made of metal or with a metallized surface. It is carried out by filling the gap between the parts with a low-melting metal, which is called a solder. Before soldering, the metal surface must be cleaned of oxides, oil, dirt, etc.
How we can increase the strength of the soldering material?
If the strength of the solder material is not enough to hold the parts, then the surfaces to be joined are tinned with a thin layer of solder, mechanically connected and soldered. The wires are twisted, the leads in the metallized holes are bent, the cases of LEDs and other elements are glued to the board.

How long does solder paste last?
The result is that the solder won't flow correctly and it becomes very difficult to get a good solder joint. The shelf life of solder paste is about six months.
What is 63/37 solder?
63/37 (Sn/Pb) . 63/37 solder is the eutectic alloy, meaning that it goes directly from solid to liquid without plasticity. 63/37 solder melts at 183 ºC. This type of solder is slightly more expensive than 60/40 but the absence of a plastic region makes it nicer to work with and more beginner-friendly.
Why is lead free solder not the best?
Lead-free solder does not have the best reputation, in part due to technical issues with the soldering process. Most lead free solder alloys melt at a higher temperature (about 220-250 ºC) than tin/lead solder (about 180-190 ºC).
Why use flux in solder joints?
The purpose of flux is to clean the solder joint as the solder is applied, thereby allowing the solder to flow, resulting in a good and void-free solder joint. The flux also changes the surface tension, which increases the solder's adhesion the metal in the solder joint.
Can you use plumbing flux in electronics?
To start at the beginning: You want to use solder intended for use in electronics – not plumbing solder. In plumbing you apply the flux with a brush and the solder itself has no flux in it. This is not useful for electronics. Plumbing flux is way too acidic for electronics use and is also incredibly messy. Flux.
Can you mix lead free solder?
Some R&D labs have a separate soldering bench set up for lead-free solder to avoid cross contamination. In general, solder alloys should not be mixed. Keeping the solder chemistry clean ensures that only the alloys the solder manufacturer intended to form actually do form when the solder cools. Diameter.
Is 62/36/2 solder stronger than 60/40?
In terms of conductivity, the three types are within a few percent of each other. The tensile strength of 62/36/2 solder is about twice that of 60/40, but whether that actually translates into mechanically stronger solder joints depends on the joint geometry.
