Tin and solder paste

Soldering is one of the ways to permanently combine the two elements. They are used in the area of electronics and electrical engineering, using solder pastes and solder tin. There are also joints connecting the two products. The choice of the right joint is important for the quality and durability of the assembly of the components that are ultimately to be found in electrical circuits or on PCBs. It depends on this factor, among others, how well the whole device will function. In the offer of the Botland store you will find a lot of products designed for connecting and fixing elements using a soldering iron. They are used both in THT and SMD technology. If you are just beginning your adventure with soldering, in addition to the soldering iron, one of your first purchases should be a bonding agent, that is tin and soldering paste. You should know that both products differ slightly in their properties and the same purpose. You should have both of them in your equipment in order to be able to choose the right one for the specific work you are currently doing.

Soldering joint types

Soldering joints are a product group that has its own properties and specific application. When choosing the right one, it is important to consider its melting point. It should be at the right low level for the connection to be durable and solid, but also visually aesthetic, that is smooth and glossy. If the connection is brittle and also tarnished, it may mean an increased risk of malfunctioning of the whole device, as well as the formation of so-called "cold solder". Soldering joints also differ in their chemical composition. It is the chemical composition that has a great influence on the final result and the efficiency of the bonding under specific environmental conditions and with the use of appropriate elements. Among soldering pastes the most popular is a mixture of tin (60%) and lead (40%). The latter component acts as a flux and definitely facilitates soldering. Due to the efficiency and ease of this process it is a solution often chosen by experienced and beginner DIY enthusiasts, electricians and electronics engineers.

If you combine SMD elements, the best choice will be soldering paste, which has an increased metal content. This will make the bonding more durable and resistant to adverse external factors. Choosing the right soldering paste increases your chances of success in your project. Moreover, it also allows you to use the full potential and possibilities of your soldering iron.

Use of solder tin

The soldering tin has to be suitable for the type of elements to be soldered. Therefore, in this case, not only the quality of the product but also the quantitative aspects are important. We therefore should pay attention to the cross-section of the soldering wire. If we are dealing with small electronic devices, also those that contain SMD elements, we choose tin for soldering with a diameter in the range of 0.25mm to 1.00mm. This is due to the high precision of soldering, but also to the relatively small distances that are maintained between the individual elements. To perform soldering of connections in circuits we choose tin with a larger diameter. This, in turn, is influenced by the need to pass high currents. In this way, we ensure the ease of making the connection, as well as the final effect at a high level. Soldering tin therefore has a very wide range of applications. We use it to connect different elements in many conditions, more or less favorable.

When soldering, not only the main device, which is the soldering iron, but also the solder joint and tin for soldering plays an important role. What also counts is the precision and experience of the person making the connection and the right choice of accessories and products for the specific materials we solder together.
