Daniel — Test Engineer

Install, repair, and upgrade laser wafer separation systems (UV and IR). Help customers determine critical requirements for installation into cleanroom facilities. Worked with process engineering to develop and identify dicing issues on silicon and gallium arsenide wafers. Wrote reports detailing repair progress and suggestions for engineering improvement. Trained customer equipment engineers and technicians on machine operation and troubleshooting.

Create designs and system diagrams for various electrical systems (Laser Drivers, TEC Controllers, Incubators, and Automated Plant Growing Systems) Use Altium to create schematics and layouts for microcontroller-based PCBs Write imbedded code for control of IOT based systems that publish data to the web Create desktop applications in C# to interface serially with microcontroller-based hardware Supervise off-shore manufacturing effort for electronic systems

Establish design parameters for successful integration of fingerprint sensors into mobile devices. Review Flex-PCB layouts for signal integrity and production readiness. Create production quality demos for display at conventions (Consumer Electronics Show, Mobile World Congress) or customer sales visits. Work with software development teams to debug Windows applications written in C++ and LabVIEW. Design and layout test boards for product characterization, ESD/EMC, and production testing. Create PCB layout guides that demonstrate best layout practices for signal integrity.

Promoted from Test Technician to Test Engineer upon completion of Bachelor's Degree. Worked in a small engineering group that is responsible for testing components used in laser video projection devices. Developed printed circuit board (PCB) schematics and layouts in Altium for product characterization and wafer probe. Developed test applications (GUIs) using C# to interface with custom in-house test systems. Created test fixtures and components in SolidWorks (3D CAD software). Used a variety of 3D printers to fabricate parts and optical mounts. Worked closely with optical engineers to develop and align laser assemblies/optics.

Worked in an engineering team that developed Analog-to-Digital Converters (ADCs) for touch screen controllers. Used PCB layout software (Mentor Graphics, Altium) to create schematics and PCBs for the entire department. Communicated with vendors to negotiate the lowest price on PCBs/components and kept track of build process. Created test programs in LabVIEW in order to collect characterization data. Fabricated and assembled prototype boards and cables for engineering evaluation. Built, programmed, and distributed customer Evaluation Modules (EVMs).
