Printed Circuit Board Manufacturing - A Closer Look

by:Rocket PCB     2020-04-20
Printed circuit board manufacturing is growing in leaps and bounds today with the wide variety of electronic equipment available in the market. Accordingly, the varieties of printed circuit boards are many. Indeed, you cannot define a standard circuit board. Their configurations vary as per their use in different products. Raw Materials Most of the PCB layout designers today use computer-aided design systems for getting precision products. As per the specific requirements of users, many different materials are used in PCB manufacturing. Copper is the best material used for PCB. These are coated with a layer of tin-lead to prevent oxidation. Again the places for contacts are plated with tin-lead, then nickel, and lastly with gold for excellent conductivity. Manufacturing Process The manufacturing process of flexible printed circuit is quite complex and sensitive. It is very important that the entire PCB manufacturing process is done in a clean environment, where the components remain free of any kinds of contamination. The proper packaging process of these flexible printed circuit boards is very important. These should always be packed in proper protective plastic bags if you wish to store them or ship them to far-off locations. Quality Control Apart from immaculate designing of it, a PCB layout designer also takes proper care to ensure quality control. This entails proper visual and electrical scrutiny from the beginning of the PCB manufacturing till the post production phase. There may be different flaws in the entire manufacturing process from misplacement of parts on the boards to application of excess solder paste to overheating the solder. This has to be rectified before using the flexible printed circuit board for various types of uses. Safety Considerations One of the most important things that are taken into consideration in PCB manufacturing is taking care of toxic materials and safety considerations. A quality PCB layout designer should take care of the harmful toxic fumes of lead (i.e. used in soldering in PCB). Also obsolete PCB should be recycled instead of filling the landfills, thus contributing to a better environment. To do away with the harmful effects of flexible printed circuit board newer varieties with water-soluble, electrically conductive molded plastics instead of the conventional materials in wires and solders. The future of printed circuit board manufacturing is immense with advancement in technology in the electronics industry. Find more about the latest PCB layout designers through online research and you would know about amazing strides this industry has taken over the years.
