Staff Engineer Working on PCB Hardware involved with high speed AI ASICs.

San Jose

Responsible for creating reference designs for many of Qualcomm’s recent main and parallel mobile switched inductor buck battery charging PMICs, Mobile companion switched capacitor buck converter PMICs and automotive core switched inductor buck PMICs. I worked closely with the IC designers to help them create the pinout of each PMIC that I worked on for the most efficient layout of both the PCB and the IC. This was done by feeding back simulations of parasitic resistance/inductance and capacitive coupling between aggressors and victim signals from prospective layouts. I also used my mechanical abilities and spatial awareness to place and escape components to minimize area required without compromising PMIC efficiency or increasing PCB cost. These reference designs were used on test hardware and reference phones or automotive reference designs throughout Qualcomm. These designs should ultimately be what ended up on the consumer phone or in the car. Responsible for the creation of evaluation boards of all of Qualcomm’s recent mobile high tier main and parallel PMICs. By referring to engineering documentation, interfacing with PMIC module leads and customer engineers, I created an efficient schematic and layout that was representative of both the best performance of the PMIC and what the customer would actually use in practice on a consumer phone. Functional bring up of PMIC evaluation boards or other hardware that I created. Work with common lab equipment, such as, DMMs, oscilloscopes, signal generators, power supplies and spectrum analyzers to determine proper operations. Extensive, debugging skills were needed when problems or unexpected results occurred. Created a digital interface board that used a Xilinx ARTIX7 FPGA and a PIC micro controller to communicate through a PC base GUI and convert SPI communication signals into Qualcomm SPMI communication signals. This board was used in conjunction with the evaluation boards to communicate with the PMICs.

San Jose Ca

Responsible for all facets of a printed circuit board design listed at my previous NBS job below. Lead designer on printed circuit boards with cutting edge technology including blind, buried, and micro vias, fine pitch BGA, high speed signals, RF design, and even ceramic package design with trace width’s all the way down to 75 micron (2.95 mil). Managed multiple printed circuit boards at once from different clients. Strong multitasking skills ensured all designs (up to 7 at once) were completed on time and within budgeted hours. A basic programming knowledge of Java was attained in spare time to make a multi tabbed multi functioned GUI program to assist in speeding up some of the design requirements.

Santa Clara Ca

Responsible for the physical layout and connectivity of a customer’s schematic according to their needs and electrical constraints, assuming all responsibilities of a design, coordinating a team of designers to complete design on time, lead designer on several complex multi layered boards, portioning out work to other designers, building symbols to represent physical components for board layout, routing, entering electrical constrains, and using programming knowledge in C++ to create programs to manipulate data generated from customer input or from our layout program itself in a way that will greatly reduce the time need for the design process. PCB design was done using Cadence Allegro PCB Editor and error checks were done using Valor.

San Jose

Responsible for ensuring that 80 customer sites per-month were within environmental compliance. This involved interfacing with the customers on site, inspecting their equipment, and filling out government regulatory inspection forms.

Martinez Ca

Responsible for calibrating, testing, and repairing high tech water and air monitoring equipment. I was in charge of the rental department and answered customer technical questions. In addition to my regular responsibilities, I also built several computers for the company and acted as the front line of IT support before our external IT provider was called. Finally, along with the rental department, I did $15,000-$30,000 in sales per month.
