Printed Circuit Board is used to support and connect electronic components. This is what the simplest electronic devices are using. Years before, PCB is out to be designed and made just within the companies but these days, custom PCB manufacturer is already recognized.
Some of the processes to be done in doing a PCB are to follow. Get your phototools ready, this is the very first thing to do above anything else. To be able to create a film, the need to have a Laser Photoplotter is very important. It will copy the data of the board and have it printed as an image. The film will proceed to the next step once it got printed.
The internal layer is what to print next. Made up of epoxy resin layer and a glass fiber core with a foil made of copper in all its side. It is necessary to always have them cleaned. This layer is covered with a film, the photoresist. A film is what you will be using as its anterior, the covered layer at the center and another film after it. There are pins in the printer that were made sure to be in line with the crater in the photo and the layer. This equipment is using an UV lamp to make the photoresist firm. Anything that was not hardened will be omitted. The firmed resist will now be the cover of the figure.
There are also those nonessential coppers that are in need to remove with the help of a solution, the Alkaline. Checking the operation is a must if you want to have an exact figure. The cover of the image will be pulled out. What is left is the specific pattern.
The internal layer is expected to be finished. It has to be placed in an optical punch for the desired pattern to be registered. The holes will be punched but will need to go under surveillance. There will be no room for any miscalculation on the inner core for it is not possible to adjust them if they will be bonded with the other layers. The first data should be examined and try to match it with the data in the board.
The next thing to do are the external layers. These are constructed from a piece of cloth that has an epoxy in it and a foil made from copper. They will merge with the internal layer that will be located at their center. The expected outcome of this process is the copper foil being the outer layer of your PCS after several operations.
There should also be a X ray drill of the reference holes, preparation of the stack for drilling, workout on the holes and cut off those resin that exceeded. Disposition of the electroless copper, having an image your outer layers, the plating, to etch the outer layers, apply soldermask, electroplate the gold edge connectors, silk screen and the cure, some electrical tests, profiling and the final inspection should also be done.
We need electronic devices to make our work easier. Without the presence of the PCB, these will never function properly. This is how important its role is.
The necessary equipment is all you got to have to be able to create your own Printed Circuit Board. That just depends on you if you want to make a personal touch out of it, or better yet let some trusted establishments have it done for you. And if you are creative and patient enough but do not have any of the equipments, then it is pretty good to be making your own design through the web and have the manufacturers make it for you. Some accept this kind of arrangement today, custom PCB manufacturer could be one great example.
