  1. P14311: PCB Isolation Routing System Final Presentation Team Members: Matthew Clark, Marley Collier Sears, Sarah Duman, Richard Kalb, Joseph Post, Zoe Rabinowitz, Kevin Richard Guide: Vincent Burolla

  2. Agenda Project Goals and Objective Engineering Requirements Testing and Analysis Current System State Suggestions for Improvement Project Lessons Learned

  3. Problem Statement and Objectives Problem: Develop an in-house prototyping system to create wiring patterns and component holes on printed circuit boards (PCBs). Objectives: • Handle boards up to 5” x 5” • Reliably and accurately drill and mill patterns with ± .001” tolerance • Easy and safe for operator use

  4. Scott Systems Rob Scott, Owner Customer and Sponsors Center for Electronics Manufacturing and Assembly Jeff Lonneville, Lab Technician Dr. Ramkumar, Director

  5. Current System State

  6. Engineering Requirements

  7. Successful Test Results

  8. Successful Results

  9. Failures and Undetermined Results

  10. Capabilities:Can we do what we set out to do? Elektor PCBA 110538-1: Radiation Monitor

  11. Suggestions for Improvement • Implement automatic functions(no operator involvement) • Homing functions in all three axes • Spindle Variable Speed Control • Mach3 Upgrades • Create macros in Mach3 to improve system flow • Buy full version • Optimize tool path to minimize machining time • Machine a level vacuum table sacrificial layer from non-porous, non-flexible material

  12. Improvements (continued) • Increased Debris Management • We’ll have a better idea of what to improve following remaining testing • Disabled Signal debugging- software or connector issue • Computer shut off issue • Limit Switches • Recovering from a limit pause- implement hand crank • Improve board design

  13. Project Lessons Learned: Technical Items • “It’s always more complicated than it seems…” • The design became complex very quickly • Read documentation for purchased parts before implementing • Through-hole components require solder on bottom- can’t solder through plastic! • Safety is important!

  14. Project Lessons Learned:Project Management • Planned expectations vs. Actual results • Scheduling • Budget • Designs • Test Results • Development of Operating Procedures • Time-consuming, but necessary and helpful
