6 Abstract Many ECpE senior design projects require the fabrication of a circuit board. To aid these projects, the focus of this project is to provide documentation on the available choices to obtain a circuit board by means of do-it-yourself methods or out-sourcing to a commercial company. Acknowledgement No acknowledgements at this time. Introduction Problem Statement Circuit board fabrication is not a simple process and as such it can take large amounts of time to research and develop criteria for evaluating which option is best for a given project. The focus of senior design projects, that require a circuit board, is in the application and not the means to obtaining or producing a circuit board due to time and financial constraints. To facilitate these groups, a process decision flow chart will be developed. The flow chart will take into account the various factors such as board size, number of components, component size, number of holes, trace widths, turn-around requirements, financial support, and quantity. The ultimate goal is to provide a suggestion of which option is best suited for the given circuit board requirements. Operating Environment Not applicable for a process project. Intended Users and Uses The intended users are ECpE senior design students with projects that require the fabrication of a circuit board. Future possible users would be others that seek to fabricate a circuit board. The intended uses are to guide in obtaining or producing a circuit board; or inform the various processes for producing a circuit board. Assumptions and Limitations 5

7 Assumptions: Server to host web site is sufficient Students have access to web site via the Internet Students are capable of generating a board layout Materials and facilities are available for fabrication No limitations. Expected End Product and Deliverables The primary end product will be a document containing a flow chart and instructions for either obtaining or producing a circuit board. In supplement to the document, an interactive web site will be made to guide the user and defer to the document. Project Proposal Proposed Approach Functional Requirements The following functional requirements pertain to the primary end product document: Given a set of factors and requirements a decision to obtain a circuit board by outsourcing or not should be answered If it is decided to not out-source then a specific process shall be given If it is decided to out-source then a list of companies and their capabilities shall be given Shall give a general description of what each process involves Shall detail the preparations, facility selection, and steps in performing each process Will contain multimedia of the process steps The following function requirements pertain to the interactive website: Mimics the functionality of the flowchart in the primary end product document Shall be a GUI that accepts user input Constraint Considerations The following constraint considerations pertain to the primary end product document: Adequate length as to not deter its usage The following constraint considerations pertain to the interactive website: Allocated server space 6

8 Technology Considerations No technology considerations for the primary end product document. The following technology considerations for the interactive website: Static or dynamic pages For static pages, use HTML or XML or another language For dynamic pages, use PHP or ASP or another language Technical Approach Considerations No technical approach considerations for the primary end product document. The following technical approach considerations pertain to the interactive website: Determination of using static or dynamic web pages shall be determined by the available software of the hosting server Determination of which static language will be dependent on browser capabilities, sufficient functionality of the language, and licensing agreements & fees Determination of which dynamic language will be dependent on server capabilities, sufficient functionality of the language, and licensing agreements & fees Testing Requirements Considerations The following testing requirements pertain to the primary end product document: Generation of scenarios to test flow chart and process instructions for accuracy and correctness Use previous senior design projects as other scenarios (possibly as reference) The following testing requirements pertain to the interactive website: Matches flow chart outcomes for all scenarios Security Considerations No security issues because there is no provided proprietary information. Intellectual Property Considerations No intellectual property issues because there is no provided proprietary information and the process is public knowledge. Commercialization Considerations No commercialization considerations because this project is for the improvement of senior design and has no commercial backing. 7

9 Possible Risk and Risk Management Possible risks: 1. Loss of access to the MRC lab through Dr. Tuttle 2. Loss of a team member Risk Management: 1. Possible access through other ECpE faculty & staff 2. Distribute project work equally Project Proposed Milestones and Evaluation Criteria Milestones: 1. Fully research processes Obtain a full understanding of the requirements to perform each process in addition to knowing how to complete each process 2. Clean up MRC PCB fabrication lab Find lab; determine available equipment; and remove unnecessary items 3. Set up MRC PCB fabrication lab Familiarizing team with equipment and locating materials & resources needed for circuit board fabrication to the point of being able to fabricate a circuit board 4. Preliminary process instructions and flow chart Rough draft of process decision tree (flow chart) and process instructions to be used in testing and documentation 5. Perform scenario testing Test generated scenarios and previous senior design project decisions for correctness of flow chart 6. Perform circuit board fabrication and document results Test all available processes for instruction correctness & accuracy and document steps & results with a digital camera 7. Interactive website completed Website implementation of flow chart done and tested for correctness 8. Primary end product document completed Corrections from testing scenarios and fabrication testing are applied to document and document is finalized Evaluation criteria: 1. Each team member is capable of describing all processes. 2. Lab is accessible to team members and all non-necessary equipment is removed. 3. All equipment present is in working order and needed materials & resources are present in the lab. 4. Rough draft is done and is capable of being used in testing without external input (i.e. from team members knowledge or experience). 5. A sufficient number of scenarios have been generated and applied to the flow chart that yields the best process for the scenario. 6. All available processes are tested and yield a circuit board of satisfactory quality. At least six digital pictures of each tested process should be done. 7. Website is available and yields identical results as the primary end product document. 8

10 Project Tracking Procedure At each meeting with Dr. Tuttle the milestones and Gantt chart shall be checked and determined if the team is on track. If the team is behind schedule, the team will need to apply more effort. The amount of effort will be determined by how far the team is behind and when the next task/milestone needs to be completed. If an unexpected cost arises, it will likely need to be funded externally due to the high cost of the equipment needed for circuit board fabrication. The only other unexpected cost will be materials needed to perform circuit board fabrication. However, no financial over-budgeting is foreseeable.

To save these projects time, effort, and money this project will guide the user to the best decision for their project s requirements and specifics. To accomplish this important task we will: Research the numerous available methods Document the steps Set up the MRC PCB lab Design & implement an interactive website Provide a document containing full instructions and images to perform each process The interactive website will compliment the document by being more readily accessible and usable. Through this project other senior design projects will be able to focus on their designs and not have to worry about obtaining or producing a circuit board. References No references at this time.
