  1. P14311: PCB Isolation Routing System Problem Definition Review

  2. Agenda • Introduction- 1 min • Background- 3 min • Problem Statement- 6 min • Stakeholders and Use- 4 min • Customer Requirements- 5 min • Engineering Requirements- 5 min • Draft Project Plan- 4 min • Issues and Corrective Actions- 2 min • Questions?

  3. Team Introductions Our Senior Design Team

  4. What is a Printed Circuit Board (PCB)? • PCB’s are boards used to mechanically support and electrically connect components. • Non-conductive substrate with copper used to electrically connect components • Copper removed/added • Components consist of through hole and/or surface mounts (resistors, capacitors, integrated circuits)

  5. Difference between PCB and PCBA • A Printed Circuit Board Assembly (PCBA) includes the board complete with all mounted components • The scope of this project only focuses on the manufacturing of PCBs

  6. Background • Printed circuit boards (PCBs) have been the cornerstone of electronic technologies for many years • Multiple iterations are typically required to finalize the PCB design • Our scope includes manufacturing single and double-sided PCB prototypes

  7. Problem Statement • RIT students need rapid prototyping for creation of unique circuit boards • Requires multiple revisions to perfect each circuit board • Currently each iteration must be created off campus • Long lead times • Expensive • Limits circuit refinement • Students not involved in process

  8. Problem Statement (Continued) • Isolation Routing System • Rapid prototyping • Inexpensive • In-house fabrication • Students control production process • Proposed System • Create boards to accommodate through hole components • Ex. Improved Radiation Meter (Elektor PN 110538-71) • Debris management system

  9. Current State Chemical Etching • Subtractive processes • Traces created from etch resist ink or are electroplated onto a substrate • Standard Leadtime ~ 15 business days (3 weeks)

  10. Competitive Benchmarking Circuit board plotting machines currently offered by Datron, LPKF, etc. • Auto tool change • Solder paste dispenser • Mill or laser cut • Fit on desktop • Roughly $12k

  11. S Third Party Companies • GM • Johnson and Johnson • Windsor • ECT Current and Future MSD Students Ryan Bowen: Robotics Lab Manager Rob Scott: PCB Hobbyist / Small Business Owner Jeff Lonneville: CEMA Lab Technician Judy Foster: RIT Environmental Health and Safety Average RIT Students (with interest in PCBs) Imagine RIT Patrons

  12. Functional PCB Isolation Routing System Prototype Circuit Schematic(s) Software CAD Assembly Drawing Packages Bill of Materials Part Numbers, Pricing, Manufacturer, Quantity, Description Safety Training and Procedures Manual Operation and Maintenance Manual Project Deliverables

  13. Use Scenarios Facilitate fabrication of PCBs for other MSD projects Students can make multiple iterations of prototype boards

  14. Use Scenarios (continued) Third Party Company Manufacturing Foundation for Continuation

  15. Customer Requirements

  16. Customer Requirements(cont)

  17. Engineering Requirements

  18. Engineering Requirements(cont)

  19. House of Quality

  20. Project Plan

  21. Project Plan (continued)

  22. Project Plan (continued)

  23. Issues and Corrective Actions Issues: • External PC not available • Undefined Safety Standards • Unknown standards for debris measurement and management Actions: • Contact Depts. for a extra/unused computer • Meeting schedule with Judy Foster, RIT EHS • Contact Particle Measuring Systems for contamination measurement instructions

  24. Any Questions? Happy Week 3 RIT!
