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.
You will then place the now transparent printed circuit board beneath the photo resist board. They should be of exact same size. The surface is sensitive after the removal of the plastic film. Placing the mask in the right way-up ensures that the tracks do not end up facing the wrong direction. The board is then ready for transfer 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 hold the board during all these operations. It is transferred into an etching tank after carefully washing in clean water. Heating allows the bubble etch tank to complete a very important process. The process involves etching away all unwanted copper materials. You will only be left with carefully drawn tracks. Success during this stage demands constant checks.
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.
Incorporation of Auto CAD system or Computer Aided Design in the process makes it simple and thus easier to complete. Data inscription is easy which makes transfer to manufacturers much easier. This automated system is able to earmark and define your required copper layers. Component notifications and soldier marks are also easy to identify using the automated system.
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.
