From Cradle to Grave: The living and close of a Circuit Board
I am writing my Senior Project Paper on overlap boards and their make on the environment. A PCB is a printed circuit board, as well as known as a printed wiring board. It is used in electronics to build electronic devices. What has gotten me interested into this consequence is my shop. My shop teacher, Mr.Cardoso actually gave me the idea. In material body one day we were talking well-nigh possible elder project topics and his big idea was called From Cradle to Grave: The Life and Death of a Circuit Board. I basically picked this topic only because I liked the title. In shop, we use circuit boards every day. A PCB serves two purposes in the construction of an electronic device; it is a place to mount the components and it provides electrical joining between the components. I work with circuit boards just ab erupt every day but there a some things I would like to know. What types of chemical substances ar used to make a circuit board? How are circuit boards made? What effects do these chemicals have on the Earth/Environment? How would you justly dispose of each chemical? How many types of circuit boards are there?



And what kind of household appliances are electronically found and have printed circuit boards in them? To start off my attend process, I searched online. I GOOGLED circuit boards. There were millions of hits. I stop up not using any of those but kind of looked up the chemicals found in the circuit boards. I was strike to see that there were so many chemicals that make up a circuit board. Most of which I have never heard of before. I found out that the main chemical found in the boards is Cadmium. I then checked out two books on the element.
