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.
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.
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 unwanted copper that need to be removed using an Alkaline solution. You need to check the process to have an exact design. The photoresist that covered the image will be removed. And by this time, you have the exact pattern.
Your internal core should have been finished entirely by this time. This will be set in an optical punch to have the objective registered. They are needed to be reviewed to see if there were any misstep. You will never be able to be changed once it is combined with the other layers. To do this is a system that will correlate the board to the actual data.
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.
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.
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.
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.
