PRINTED CIRCUITS COMPONENTS FOR A JIT FACTORY Mr. Carl Burger‚ supply manager at Acacia Company‚ is faced with a problem of researching several electronic components for a new graphic plotter‚ manufactured in a just-in-time environment. Acacia Company is a major producer of graphic plotters‚ renowned for top-quality and innovative products. The newest unit in the product line is the 440A‚ a relatively inexpensive eight-pen‚ A-size (8½” x 11”) plotter‚ designed for use with personal computers

What is a breadboard? A breadboard is used to build and test circuits quickly before finalizing any circuit design. The breadboard has many holes into which circuit components like ICs and resistors can be inserted. A typical breadboard is shown below: The bread board has strips of metal which run underneath the board and connect the holes on the top of the board. The metal strips are laid out as shown below. Note that the top and bottom rows of holes are connected horizontally while the

So I took the initiative to create a new product‚ which can overcome some difficulties faced by this group. Our latest creation called "Whiteboard Cleaner". In this report contained all the information about circuits and operating the project as well as the equipment used during this project. OBJECTIVES

Donner Company Case Overview Donner Company manufactures printed circuit boards for both large and small companies‚ specializing in experimental devices and for pilot production runs in the late 1980s. The circuit boards that it produces are made from thin sheets of narrow metal strips and insulating material. The process to produce each circuit board is very meticulous and involves many intricate steps. Their process‚ otherwise known as the “soldermask over bare copper” (SMOBC) process includes

convection oven. Comparisons of the electronic assemblies to an industrial IPC standard illustrated that it is possible to develop a circuit‚ which is deemed acceptable under this standard. It can be concluded therefore that a screen printed conductive ink pattern‚ when printed on a degradable substrate can offer a viable alternative to current printed circuit boards and can be manufactured using existing technology and manufacturing processes. 2 Optimisation for Surface Mount Placement Machines

manufactured printed circuit boards to the specifications of a variety of electronics manufacturers. Each board consisted of a thin sheet of insulating material with narrow metal strips (conductors) bonded to its surface. The insulating sheet acted as a structural member and supported electronic components connected by the conducting strips. In the customer’s plant‚ assemblers (human and/or automated machinery) positioned electronic components in the predrilled holes in the board‚ soldered them into
