• Independent Schematic design and PCB board layout Project (Test platform)o Designed 2-layer PCB board used for testing I2C devices using Protel 99 SE -Designed custom footprints and custom schematic symbols.o Worked with vendors and suppliers to order components to populate board. Created Gerber/Drill files to prototype board through vendor.o Gained exposure to I2C communications and timing diagrams.o Soldered components to board. Footprints varied from 0402, SOT-223 to TO-263.• Worked to design new implementation of Force Sensor resistors (FSRs)o Tested linearity characteristics of force vs. resistanceo Designed and compared circuits to optimize linearity in region of interest. -Compared configurations which made use of BJT current mirror, FET current mirror, and OPAMP.-Compared hand analysis calculations, simulated results (SIMetrix), and real results with circuits on SMD prototype board. -Worked with vendors to obtain necessary parts.• Independently managed and completed qualification of vendor parts.• Performed failure analysis on test boardso Unexpected current readings during qualification. Root cause found to be MLCC cracking, leading to a reduction in the insulation resistanceo Communication errors. Root cause found to be flux remover liquefying in environmental tests leading to non-conductance in connector.o Part failures. Validated through diode/continuity tests.
