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.
Electronics can appear very confusing to the average person. So much so that often people feel that the reason why something works is not an important factor providing that they can make the item do what they need it to do. Happily there are individuals who do know 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.
On opening up one of these items you will immediately notice a flat board. This will normally either be brown or green in colour, and is called the printed circuit board. You will notice that there are metallic tracks on one side. These tracks are used to conduct power only where it is meant to go.
These Printed Circuit Boards will normally be one of two types. The type used is often dependent upon various factors, such as complexity and the amount of room available within the item. The types are either through board or surface mount, and the surface mount can be either single or double sided.
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 either of these circuit boards have had all of the components securely fitted they are given a conformal coating. This helps to provide additional protection. This explanation will help the average person understand the processes used in the manufacturing of PCB boards.
