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 consider how many things you use each day that utilise electronics in one way or another. For these items to work properly the electronic components have to be set out in a particular order. Once the cover is removed from one of these items it becomes easier to see how this is fulfilled.
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.
Whichever type is being produced there are a couple of things that the operative requires, good eyesight and a steady hand. Without either one, creating one of these printed circuit boards gets much more difficult. The other elements, such as identifying the components and how they should be fitted can be taught.
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.
Once all of these components are secured in their correct positions the board is then given a conformal coating. This will prevent any stray dust bridging across any of the component legs, or the tracks. Hopefully you will now have more of an understanding about some of the things which need to happen during the manufacturing of PCB boards.
