Any device, even the simplest one, will never work if there is no reliable foundation that will take hold of their functions. This is how important a Printed Circuit Board could be. In the latter age, customizing your board was not given the chance to be practiced but in this generation it is fully appreciated. Establishments like the custom PCB manufacturer show support to those artistic minds.
The first five steps on how to make a Printed Circuit Board are included here. For one, it is a must to get all your stuffs ready before starting doing something. You need to prepare your phototools. Films are to be made in this process, Laser Photoplotters are most needed. These will copy the information that the board has and make a copy of it through digital image. The film will come out from the photoplotters and will be forwarded to the following step after.
Now you will be printing the inner layer. This is composed of a layer of epoxy resin and a core made up of glass fiber with a copper foil in each side. Make sure to clean them. This cleaned panel is coated with a photosensitive film called the photoresist. The first film, then the coated panel to be followed by the second film. The pins in the printer were aligned with the holes in the phototools and panel. The printer uses powerful lamps that harden the photoresist. The unhardened resist will be removed. The copper pattern will be covered by the hardened resist.
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 external core is to be considered important. It will be created in this stage. A cloth with a resin on it, and a foil that is out from copper made up this layer. This will be paired with the inner layer that is put in the center. The copper foil will become the external core of the PCB after several processes.
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.
You could always choose to yourself whether to personally make it only if you have the needed equipments, or ask other people or companies to do it for you. You just need to order it from them. But if you want to design your own board, there are a lot of manufacturers that accept that nowadays. Growing numbers of businesses focus on mechanical and electrical fields, just like the custom PCB manufacturer.
