Step By Step Manufacturing Of PCB
Manufacturing of PCB has been simplified through innovation and advancement in technology. You will require a photo resist board which forms the basics of the entire assembly. This is a piece of glass with reinforcements made of plastic. On the one end is a photo sensitive copper coating. It is by peeling this plastic film that one reveals the photo sensitive coating.
The transparent printed circuit board is placed beneath the photo resist board. It is important to ensure that you select boards that are of equal size. It is the removal of the covering plastic film that makes the surface sensitive. Care should be taken to place the board in the right way. It will prevent the tracks from ending in the wrong way. These are the preparatory steps that make the board ready to be transferred into the UV light box.
The lid to the box should be appropriate in order to make the box completely covered. The box should be switched on for about two and half minutes. This board should only be handled using plastic tongs because of its delicate nature. The board is then transferred into the development box. It takes slightly more or less than ten seconds in this box and then it is removed. Extending time in this box is dangerous and could destroy it completely.
Plastic tongs are used to transfer the board to the etching tank after it has been thoroughly cleaned using water. The box is switched on for heating until bubbles form. This process is supposed to remove excel copper material in order to leave the tracks clean and clear. This process should be closely monitored to ensure that the tracks are not damaged.
Etching takes between fifteen and forty five minutes. Letting the board remain in the tank for too long is likely to damage the tracks. There is a possibility that those tracks may get removed or damaged. This calls for caution by ensuring that the entire process is carefully monitored, minute by minute. Experience will make the process faster and more accurate.
Technology has simplified the process of design since a Computer Aided Design system or Auto CAD may be used. The data is easier to in-script and transfer to manufacturers. This automated system defines and earmarks your copper layers. It makes it easier and clear to identify soldier marks and component notifications.
Laser photoplotters are used during preparation of photo tools. This is done in a controlled dark room where the humidity and temperatures are monitored. The board data is taken for conversion into an image based on pixels. Writing on the film is done using a laser writer as well. Upon exposure, the film has developed automatically and is ready for unloading for the operator.
Manufacturing of PCB is complete by V-cut scoring or profiling. This is best done on the production panel. You will require a scoring machine to accomplish this. The cuts are made at a third of the entire thickness to allow the board to remain intact. An expert should then check the entire board carefully to be certain that it meets all your expectations.
