Ensured products’ cellular communication performance met requirements and complied with 3GPP specifications; Brought multiple products from early NPI stages to mass production. Team Leadership & Project Management ▪︎ Led a 16-engineer team for RFFE integration, achieving outstanding team performance in Apple IDL reviews. ▪︎ Managed resource allocation, task prioritisation, and risk management to ensure on-time milestone delivery. ▪︎ Collaborated with 8+ cross-functional teams and customers to ensure timely issue resolution. ▪︎ Successfully overcame challenges in the 4G to 5G transition within schedule, including RF modem supplier changes, testing platform migration, and integration of new NR, mmWave, and satellite modules. ▪︎ Developed automation tool that reduced RF bench testing cycle time by 25%, earning the 2022 Q2 FX NPI Innovation Award. RF Engineering ▪︎ Verified the performance of RFFE components such as filters, switches, PAs, and LNAs. ▪︎ Performed RF circuits impedance tuning and analysed S-parameters, Smith Charts to meet performance targets. ▪︎ Troubleshot board-level RF Tx/Rx issues, with NPI builds receiving >300 units for team analysis.

Led a 10-engineer team in SMT process development and optimisation to ensure feasibility for mass production. ▪︎ Designed and reviewed SMT fixtures, stencil apertures and transfer trays. ▪︎ Defined and optimised reflow profile, solder printing parameters to prevent and reduce soldering issues. ▪︎ Defined underfill patterns and review underfill strength by cross/planner-section and dye-pry. ▪︎ Developed flow charts, control plans, and standard operating procedures for SMT processes. ▪︎ Resolved the M1 chip solder open issue by optimising stencil aperture, reflow profile, and fixture skybar design, resulting in an improvement of the failure rate from 10% to under 0.01%.
