Having the skills to solder electronic components is an essential part of working as an electronics technician. It’s also a useful skill for anyone who likes making things and fixing broken things in their own time.
If you have ever tried your hand at repairing gadgets or putting together a make-it-yourself kit, you may have noticed that soldering is almost always involved somewhere – either in assembling the pieces or fixing something when it goes wrong.
Soldering electronic components is not hard to learn but it can be challenging at first because you need some special equipment to do this job well. However, with these helpful tips and tricks, you will be able to master the art of soldering in no time!
What Does Soldering Electronic Components Involve?
Soldering electronic components is the process of joining two pieces of metal by melting and flowing a metal alloy called solder. The melted solder then flows between the two pieces, binding and creating a strong joint.
Soldering is used in almost every electronics project to join components together such as wires, circuit boards, and electronic components. There are many reasons why you might choose to solder electronic components as opposed to using other techniques.
First, it is a fast and effective way of joining parts together, and second it creates a durable joint that is highly reliable and robust. This is because the joint created is mechanically stronger than the materials being joined and is resistant to vibration.
Equipment Needed for Soldering Electronic Components
Soldering Iron – This is the tool you use to apply heat to the metal components you are soldering.
Solder – Solder is an alloy that melts when heated and flows between the components you are joining to create a strong and permanent joint. There are many types of solder but the most commonly used type is an electrical solder that is used to join electrical components together. There are many different types of electrical solder but the most common ones are 63/37, 36/63, and 60/40 rosin core.
-Third hand – This is a tool that helps to hold your components in the correct position for soldering.
-Solder sponge – This is used to clean any excess solder left on your iron after soldering.
-Wire cutters – Used to cut any excess wire that you will not be using.
-Solder braid- This is used to create a joint that is stronger than solder alone.
-Solder sucker – Used to remove the excess solder from your components.
-Solder board – Used to hold your components in place while you solder them together.
-Electronics desoldering pump – Used for removing the excess solder from your components
-Solder removal tip – This is used for removing the excess solder from your components
-Components – Electronic components are used to make electronic devices such as calculators, computers, or cell phones. Components come in all shapes and sizes and are usually packaged in plastic bags with a piece of paper inserted into each bag showing what type of component it is. The most common types of electronic components include resistors, capacitors, diodes, transistors, integrated circuits (ICs), and light-emitting diodes (LEDs).
-Plastic bag with component guide printed on it – Plastic bags with printed guides on them are used to package electronic parts so they can be easily identified.
Reasons for soldering electronic components
There are various situations that will push you into soldering electronic components. Some of these situations include:
-Soldering wires into the board: This is a common process that needs to be done when you first assemble your project. The most common wires that are soldered are the power and ground wires.
-Circuit board repair: If your project has components that have broken, then it is likely that you will have to solder in new components or repair the circuit board.
-Repairing broken parts: This is when you have a part of your circuit board break and need to replace it with a new one.
-Soldering parts onto another part of the circuit: In this situation, you may need to replace one of the electronic components on your circuit board with something else such as adding an LED or changing a resistor value.
-Adding additional components: Adding additional parts to your project can be done in any number of ways including adding resistors, capacitors, transistors, or LEDs.
-Resoldering components: Resoldering is basically the process of replacing a component that has been removed from a circuit board. You may need to do this if the component has broken.
-Replacing components: If your circuit board has components that are broken, then you will need to replace them with new ones.
-Testing components: To test the functionality of your circuit board, you will want to be able to turn it on and off and check if each component works properly.
-Replacing electronic parts: If you have electronic parts that are broken or damaged, then they will need to be replaced with new ones.
Solder Types and Which to Use When Soldering Electronic Components
There are many types of solder on the market but the most common are 63/37, 36/63, and 60/40 rosin core.
– 63/37 is a general-purpose solder that is good for a range of electrical applications and joining dissimilar metals together. This solder is easy to use, has a low melting point, and is relatively cheap.
– 36/63 is a high-temperature solder that is best used in applications where you need to join metals together that have high thermal conductivity.
This solder melts at a higher temperature and is more expensive than 63/37.
– 60/40 rosin core is a high-quality soldering wire appropriate for precision electronic work and for joining electrical components together. This solder melts at a lower temperature than the previous two solders and is more expensive.
This solder is especially ideal for joining wires to terminals and pins. – It is important to choose the right solder to join your components together as you don’t want to join the wrong metals together or use the wrong type of solder and damage the components.
Despite the different types, lead-free rosin core solder remains to be the most preferred type of solder used on electronic components. The main reason is that lead-free solder melts at a lower temperature and is more stable than other types of solder. This is especially beneficial when soldering delicate electronics as the components are likely to be damaged if the soldering temperature is too high.
Things to know before you solder electronic components
– Make sure that you have everything you need before starting to solder the components together. You don’t want to be mid-way through soldering and realize that you have run out of wire or that you don’t have enough solder.
– Always make sure that the components you are about to solder are clean before you start. Any dirt or grime will prevent the solder from bonding properly and can also damage the components. Use a cleaning solvent to wipe off any dirt from the components and a clean sponge to wipe down your iron.
– Make sure that your soldering iron is clean. A dirty iron will not transfer heat properly and will ruin your solder joint.
– Make sure that your iron is at the correct temperature before soldering. If it is too hot, the solder will melt before the joint is ready and you will get a bad solder joint.
– Make sure that you have the right amount of solder. You don’t want too much or too little. Too much will result in a messy solder joint and too little will cause a bad joint and can cause the solder to be re-solidify inside of the joint.
Steps for soldering electronic components
Step1: Set up your equipment: Make sure that all of your equipment is clean and that the iron is at the right temperature to solder the components together.
Step2: – Clean the surfaces: Clean both surfaces that you are going to join with a solvent to remove any grease and grime. This will help the solder to flow and create a strong joint.
– Select the correct joint: Select the correct joint for the components you are joining together. For example, if you are joining two wires together, you want to use a solder joint called a “solder joint”.
– Apply heat to the joint: Hold the iron against the joint for a few seconds to apply the correct amount of heat. Be careful not to apply too much heat and damage the components with the iron.
– Add the solder: Add the solder to the joint and allow it to melt before carefully removing the iron. The solder will flow between the components and create a strong and permanent joint.
– Clean up: Clean the iron and remove any excess solder with a solder sponge before storing.
Important Tips for Soldering Electronic Components
– Always make sure that you clean your components before soldering them together.
– Always use the right joint for the components that you are joining together.
– Always use the right amount of solder. Too little solder and you run the risk of a bad joint, too much and it will be messy.
– Always make sure that the iron has reached the correct temperature before soldering. – Always use the correct solder for the metals that you are joining together.
