Custom PCB Manufacturer And Its Wonder

By Dawn Williams


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 outer layers will be created. It is composed of cloth with an epoxy resin and a copper foil.These will be bonded with the inner core put at the center. Cycles will be done and by the end of this process, copper foil is expected to have bonded to become the outer layer of your PCB.

Some other steps also need to be performed to finally have the desired outcome. Drills regarding the X ray of the holes, preparing the stacks for it as well, cutting of the resin which were not needed are a few of those. There should also be plating, tests in electrical factor and the inspection for finality.

It has been common to everybody the use of electronic devices. Some might have not known that it is the PCB who is responsible for all their functions. This board plays a very important role in our daily activities.

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.
