Bisphenol A (BPA) Bisphenol A is a harmful chemical found in most everything made of plastic. It is in obvious things‚ such as paint‚ and it is in not so obvious things such as baby bottles. Small amounts of BPA are harmless to humans‚ but extreme amounts of BPA can have life threatening affects. BPA is used to make Polycarbonate Plastics. The Plastics produced are the lightest weight and the toughest of all plastics. Approximately 2.8 million tons of BPA is produced yearly in the world. Studies

The most critical part‚ the Cable and Fiber Preparation where the fiber is mounted‚ is the ferrule. The Ferrule is a long‚ thin cylinder with the fiber mounted in the center hole. The center hole is sized to match fiber’s cladding diameter which is usually 125um. When fiber connector ferrules are made from several types of materials including ceramic(Zirconia)‚ stainless steel and plastic. The ferrule’s job is to center and align the fiber and protects it from mechanical damage. The end of fiber

high degree of magnification to properly see the dies. Bad dies are inked or marked to distinguish it from the good die. The good die is attached to a leadframe and into the die paddle by a die bonding machine. Adhesives that can be used are glass‚ epoxy‚ or gold preform. The die attached strip will be cured/ baked in a furnace to harden the adhesive. Lastly‚ the circuitry of the IC is established using copper‚ palladium‚ or gold wire. The finsihed wire bonded strip will still be inspected and will

Spaghetti Bridge Abstract For this assignment our task was to build as a group a spaghetti bridge with the objective of carrying the most weight as possible using only spaghetti and hot glue‚ meeting the specifications. The bridges will be loaded until they fall. After testing to destruction‚ the bridges loading capacity was 14.4kg‚ with an initial mas of 0.840kg. This gave a weight to strength ratio of 17.1 putting the group at 4th/8th position in class. From this it was learned the
