What You Need to Know About PCB Design
The word PCB refers to polychlorinated biphenyl, and it is a family of stable industrial compounds. Common uses for PCBs are lubricants, heat-transfer fluids, plasticizers, and solder pastes. These chemicals are banned in the United States since the 1970s due to their toxic effects on the environment. Especially harmful to invertebrates and fish, PCBs remain in the food chain for years. A PCB can be made of several different materials. In a typical manufacturing process, a PCB is comprised of a layer of copper, a conductive layer of indium, and a layer of silver. During the fabrication process, the board is laminated, and then the soldering process takes place. The final step is an inspection to ensure that the PCBA works as it should. A thorough check will ensure that the boards are free of any visible defects and are of the highest quality. Printed circuit boards are made by applying a conductive metal to a nonconductive surface. These materials are then laminated together to form
