Custom PCB Manufacturer For Good

Custom PCB Manufacturer For Good

By Dawn Williams


We always use electronic devices but may have not known what is behind its functionality. These use a Printed Circuit Board to associate one segment to another. Designing your own board was never acknowledged in the past few years. But today, some of the companies like custom PCB manufacturer accept this idea.

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 inner core is now complete. The core will be put in an optical punch to line up and register the targets in the pattern. Registered holes will be punched, but the panel will undergo an inspection. There should not be any mistakes on the inner layer because you will not be able to correct them once it gets assembled with the multi layer. An automatic system will scan the board and will compare it to the original digital data. Any errors will be shown in your screen.

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.

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.

Electronic devices are very useful in our activities. Any device will not function if there is no PCB in it. This thing is playing a very significant role.

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.
