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)

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

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

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

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 )  Debris management system

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)

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
