Custom PCB Manufacturer For Good

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.

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.

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.

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.

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.
