Electronic Hardware Development

• Developing the board specification document, block diagram, preliminary part list, and schematic capture as per the hardware requirement specification.
• Developing the circuits with the schematic capture tool (Altium Designer V 20.0.11), which includes selecting components, obtaining part samples, testing sub-circuits, calculating power requirements and design calculations, defining layout requirements, and running simulations and analysis.
• Assisting the component engineer, which includes the information of the component to be entered in the database, component drawing, assigning a part number, and researching multiple component sources.
• Reviewing the PCB design layout includes component placement as per the recommendation of the IC manufacturer, trace routing, shielding considerations, grounding and ground current control considerations, and EMI considerations.
• Assisting in the PCB fabrication and assembly.
• Testing of the PCBA includes the DVT (design verification test) document, a prototype bring-up check list, electrical characteristics, subsystem test, functionality test, and performance test. Once testing is done, boards are available for integration in the higher assembly.
• Defects found in the testing of PCBA boards are documented and tracked; once the root cause is identified, corrections are made, validated, and incorporated into the next revision of the PCBA.
