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 printed circuit board that is already transparent goes below the photo resist board. These two boards should be of the same size. The sensitivity of this surface is arrived at by removing the plastic film. The boards should be aligned to ensure that your tracks do not end up in any other way apart from what you intended. This is the level of manufacture that prepares the board for placement into the UV light box.
An appropriate cover should be placed on the box to ensure that it is completely shut. The UV light box is then switched on and left to run for approximately two and a half minutes. Plastic tongs will be used to get the board out of the box after which it is placed on a tank ready for development. The approximate time the board should be left in the box is ten seconds. It should not exceed this limit or go below it by considerable margin.
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.
