Printed Circuit Boards
Printed circuit boards were invented in the1930's and are used in a
variety of electronic circuits. The uses range from simple
one-transistor amplifiers to super computers. Printed circuit boards
are a large part of technology in the modern world. They can be found
in products such as cars, toys, TV's, computers, telephones, oven etc.
In my report I am going to itemise and explain the process involved in
producing a printed circuit board with the characteristics below.

There are many methods to making printed circuit boards. The first
method is a traditional manual method. It involves using subtractive
techniques; this is where the excess copper layer is removed from a
board coated in copper, therefore leaving the artwork exposed. This
traditional method of making a printed circuit board involves six main
stages.
The first is drawing a schematic diagram of the circuit; this is the
diagram to show the circuits components and how they are connected.
The schematic diagram can be designed in many different ways, it can
be drawn and designed by hand and then transfer the image onto the
circuit board. Computer aided design can also be used to design the
schematic drawing by using applications on software on a computer. By
using computer aided design to design the printed circuit board it
makes the task a lot simpler because it's easier to decide on the
location of components, and the drawing of the interconnections. There
are special schematic computer packages that will help to design the
printed circuit board by it picking components, rout traces to
artwork, check your design and then at the end find missing
connections, spacing violations and many other problems. The schematic
diagram is usually tested using a prototype before committing to a
printed circuit board. This will verify that the symbols and words are
an accurate representation of the circuit you want to build.

The next step to making a printed circuit board is to design the
Esquire Radio & Electronics, the plaintiff, has filed a law suit against Montgomery Ward, seeking damages for a breach of contract.
Focus shall be on utilizing pre-production tools while developing the prototypes. Actual material, wherever possible, shall be used in the development of prototypes rather than having substituted parts. Make the prototypes as closer as possible to actual outputs.
My animal is the southern flying squirrel (glocomys volans) and it is an endothermic vertebrate. This Squirrel is a really cool squirrel because it can fly! Well it can’t actually fly; it can glide from tree to tree trying to find food. The foods that Southern flying squirrels eat are mostly grasshoppers and crickets, because it’s a carnivore. But they also eat nuts and berries too. The flying squirrel eats at a rapid place and likes to store food in its nest to eats later.
The process starts with a concept or idea.(Mashable) The first stage of 3D printing is planning out this concept with either computer aided design or animation modeling software. There are tons of programs out there today with these capabilities. Google SketchUp for example is known for being easy to use.(3ders) Using some easy tools that can be learned quickly, edges and faces can come together to make very intricate models. It can even be used with Google Earth. All those models of the world in that software are made in what is basically the same process digitally. Blender is the free 3D creation program that exists for the needs of major operating systems.(3ders) It is a high end software containing features that are much more capable than Google SketchUp. Tinkercad is a newer way of creating designs for 3D printers and works slightly faster than the others.(3ders) Containing only three simple tools, it’s effectiveness for creating models is among the best..

In nineteenth-century society, a time well versed in the uses and advantages of Gutenberg’s printing press, the typewriter changed the way people thought about writing. Since the introduction of the printing press four centuries earlier, there had been a very limited amount of new inventions pertaining to writing or the world of the mechanized press. Advancements certainly had been made to modernize the printing process, but the typewriter was the next invention that would change the face of writing. The typewriter made writing more common and accessible and loosened up proper business etiquette. Professionals shifted from the mindset of having to write a handwritten letter regarding company updates and accepted the notion of being able to type out a business memo. The process of typing also affected the way authors wrote and what they thought about writing as it allowed them to become more involved in publication.
The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset. On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster CP by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely. (Glossary)
Until recently, 3D printing was only utilized by product designers and hobbyists working primarily with plastics and was not available to the mass market. With the recent price drop of 3D printers and availability of 3D printing materials, the popularity of 3D printing has dramatically increased in the last couple of years. It has been estimated that 3D printing could generate an economic impact of $230 billion to $550 billion per year by 2025 (McKinsey Global Institute, 2012).
the steps and procedures you would need to take to properly design it. First thing you would need
...he organization. The output of the design group’s efforts is detailed drawing and other specifications, which assist the succeeding groups for effective usage of the raw materials into a finished product. This information is also important for the product
Imagine printing what ever it is you need from your own office or home. In addition to that, you will have full control customizing the product and the printer will have no difficulties achieving your designs. All you have to buy is the ink and the material additives and the printer will do the rest.
The second way is by using computer aided drafting (CAD) and computer aided manufacturing (CAM) programs on your computer.
The topic I have selected for my essay will be on 3D printing in education, I chose this emerging technology because of my place of work and how 3D printing may be involved their within the next few years. This would require me to research how 3D printers work and how to operate them. I also believe that having 3D printers in schools will generate a new wave of creative children in the future. In this essay I will be showing how a 3D printer works and how the machines operate. I will be providing example on why I think 3D printing is important for education, as well as showing what hurdles 3D printing has to overcome in regards to Intellectual property rights and the legality of what you can and cannot print. In this essay I am going to point out the advantages of what a 3D printer can achieve for the future and how it can possibly shape the way we educate our children.
