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.
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.
A controlled dark room makes preparation of photo tools easier. This is done using laser driven photoplotters. The room has the right temperature and humidity conditions for work. Converting the data used in manufacture of the images into a pixel image simplifies the process of manufacture. The film is written using a laser writer. The film is ready for unloading by the operator after automatic film development.
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.
