Soldering electronic components – what you need to know

 

Soldering is a process that fixes one or more components, one at a time, after dissolving and running a soldering tool in a joint. This method can be applied to a variety of electronic and electric process and can be done in order to combine certain components with roots attached to a circuit board. Keep in mind, though, that the solder metal has a lower melting temperature compared to the working piece.

 

 

There are different methods used for soldering, such as soft soldering and hard soldering. The first one, soft soldering, is suitable for fitting extremely small components that possess a low liquefying level of temperature. During this process, a tin-lead alloy serves as a space filler metal. Plus, in order to get plenty of heating, you need to use a gas torch as source of heat.

Hard soldering, on the other hand, unites two metal components after spreading them into the holes of the component. In this case, the space metal filler reaches extremely high temperatures that go above 840 Fahrenheit degrees.

 

Before starting the soldering activity, you need to take certain safety precautions. For example, never touch any element nor the tip of the soldering iron because they are incredibly hot and can cause severe burns. Also, it’s best not to touch the mains flex using the tip of the iron. The majority of the irons are outfitted with a heatproof flex that enables more protection. If you opt for a cheaper model that has an ordinary plastic flex you risk getting burned and suffering from an electric shock if touched by a hot iron.

Under no circumstances put the soldering iron on your workbench or in any other place except its own stand. You have no idea how many damages you can cause to that exposed surface.

Because during the melting smoke is created, it’s best to do this in a well-ventilated area. Otherwise, it can be irritating to your eyes. Try to avoid, as much as possible, to keep your head on the opposite side you are working to prevent breathing the smoke.

 

 

After each usage, make sure you watch your hands thoroughly. Many solder units contain lead which is known to be poisonous to the human body.

If you have the possibility, use a soldering iron that features a heatproof silicone cable that is much safer especially if you accidentally touch the hot iron during the process.

Before using the iron, place it its stand and plug the device in. In a few minutes, the tool should be ready to operate. Then, dampen the sponge lifting it out of the stand and holding it under a cold tap of water for a few seconds. You can squeeze the excess water because it’s important that the sponge is damp and not dripping wet.

 

What you need to know about micro soldering microscopes

 

In order to be able to see microscopic components, you need a proper tool to do so. For example, if you’re health is not top-notch, your physician needs other help besides the actual body and symptoms examinations. Therefore, using a soldering microscope that can determine whether you suffer from something just by looking at your blood cells is an important part of the process.

Although many beginners in the field then to opt for microscopes outfitted with articulating stands, these aren’t so stable and tend to move when vibrations are involved, such as hot air stations or people that enter the room. Plus, they are hard to work with because it’s a tad difficult to keep them in one position. They can always drift away and make it impossible to find the exact position that allows the specialist to see everything in full detail.

If you choose single boom stands, these feature only one cylindrical arm that connects the head with the base. Besides this, if the device doesn’t have a locking pawl, you’ll have to lock and unlock the unit every time you want to move it in a certain angle. Double boom microscopes, on the other hand, enable the arm unlocked without having to rotate the head.

 

In order to be able to choose the field of view and magnification for the specific situation you are working on, you need a tool that comes with a variable zoom between 0.5X and 5X. This way you can rest assured you can zoom in if you need to inspect joints or solder objects closely.

The eyepiece is responsible for providing a powerful magnification. A high-quality microscope boasts modular eyepieces that you can swap for lower or higher magnification, according to your preferences and needs. You can calculate the magnification using the eyepiece and the objective lens magnifications.

Because you need comfort while staring at microorganisms all day long, the microscope should also provide rubber eye cups that keep your eyes in proper positions. Furthermore, you can adjust the eyepieces width so you can see through both of them simultaneously and fine-tune the focus using the focus knob until the picture is crystal clear.

Because you need to be able to work for longer periods of time when using the soldering microscope, the working distance is another factor to be considered. This aspect refers to the distance located between the workplace and the objective lens when you are using the focus to examine certain objects. There are units that feature Barlow lenses that can increase this distance which comes in handy if you work with motherboards that are heavier.

Don’t overlook the camera, as well. This tool is extremely useful because it allows technicians to assist one another and also to show other people what’s going on under the microscope.
