Everywhere you look, or go, in these modern times, there is always technology there with you. It is true to say that technology has made people's lives so much easier. Many people are happy to use this technology, but few understand the processes behind it. At the core of most of the technology is the field of electronics. For electronics to work someone, somewhere, has been responsible for the manufacturing of PCB boards.
For most people, whenever electronics are mentioned, their eyes begin to cross. They don't really need to know how things work, they just need to be able to use it when they wish to. Thankfully there are some people who do actually understand these things.
Just a quick glance around you will give you an indication about how many items utilise these electronic items. They can not be used in a random manner, so they have to be fitted in a specific pattern to create the desired operation. If you take the back off of one such item you will see how this has been accomplished.
The electronic components are held on something known as a printed circuit board. This board will either be green or pale brown in colour. If you look closer you will see metal tracks on one side of the board. These tracks permit the electrical current to be delivered only to where it is allowed.
There are basically two types of Printed Circuit Board. Depending on the density of components and the tasks they are asked to perform will dictate which type will be used. These two types are known as surface mount or through board.
Either type requires a steady hand and a good eye. The other requirements can be taught, but without the other two elements, populating a printed circuit board becomes very difficult. One thing that has to be successfully taught is the identification of these electronic components and how they will be fitted.
The through board is the most common type of board that people will see. The bodies of the components are located on the other side to the track lines. The legs of the components get fed through the board, and are then soldered securely in position. This is where the name type is derived from. To prevent the legs creating a potential hazard they have to be cropped closely to the board. One benefit with this type of board is that the components are of a size that is easy to identify and handle.
The surface mount board has the components mounted actually on the tracks. The components themselves are a lot smaller, and are more difficult to handle. A lot of the assembly work for this type is carried out under strong magnification and bright lighting. The magnification is necessary to prevent possible short circuits.
When the technician is happy that all of these components sit in their right places on the circuit board, they will then apply a conformal coating. This is another means of protection which is applied. So now when you see an electrical item you will have a greater awareness about how firms manage the manufacturing of PCB boards.
