Custom PCB Manufacturer To Be Enjoyed

By Dawn Williams


Printed Circuit Board is used to support and connect electronic components. This is what the simplest electronic devices are using. Years before, PCB is out to be designed and made just within the companies but these days, custom PCB manufacturer is already recognized.

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.

A chemical named Alkaline will be used to take away the unnecessary copper. The procedure must be tracked to have the same construction. In this stage, you will be having the definite 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 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.

Moreover, drills in X ray of the holes, preparing of stacks, and pulling out the overflowed epoxy are required to be done, too. It also includes capturing your external core, plating, put soldermask, encrust the connectors, silk screen, tests that are something to do with the electrical components and eventually the overall review.

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.

Every now and then, we want to be unique among others. Making your own Printed Circuit Board could be a good start. Whether you have the equipments or not, you can still have it customized through some of the companies that will accept it. A lot of them, like the custom PCB manufacturer will help you have it personalized.
