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 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 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.

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.

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.
