Our Senior Design Team

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 110538-71)

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
