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.

Here are the first five steps in making a Printed Circuit Board. Preparing the phototools is how you will start everything. Laser Photoplotter is used to make films. It takes the data of the board and eventually converts it to a pixel image. After a while, the film will be loaded and is now ready for the next step.

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 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.
