Manufacturing of PCB has been made simple with the introduction of technology in design and preparation. This innovative approach allows manufacturers to achieve better and more precise results. You will be required to get an appropriate photo resist board that has plastic reinforcements on glass. One of the faces of this board is photo sensitive and coated with copper. This surface is initially covered with a plastic film.
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.
The entire process of etching lasts fifteen to forty five minutes. Exposing your board for less time makes it undeveloped while allowing it to stay for too long will lead to damage. The tracks may even be removed. Monitoring must be on a minute to minute basis. It takes experience to master the entire process.
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.
Profiling or V-cut scoring is the process that completes manufacturing of PCB. The process takes place at the production panel and uses a scoring machine. A third of the board is cut to ensure that it remains intact. Engaging an expert ensures that the entire process of manufacture meets your expectations.
