Philips, Andover, MA

R&D Development Engineer in Ultrasound 6/2017-2/2018

Planned, designed and executed a series of tests aided with statistical analysis (Minitab) for the evaluation of bond strength of different layers in transducer stacks to standardize the comparison of the bond strength within transducers. At the end, the findings clearly and comprehensively provided a perspective of the situation and offered the proper processes, raw materials and reliable material suppliers for the business.

Investigated and characterized surface roughness and chemistry of the matching layer using different techniques such as ZYGO, AFM, SEM, and XPS for connectivity issue, and finally found the rootcause of the failure and suggested the corrective actions to fix the problem for a state-of-the-art new product innovation.

Contributed and built prototypes to evaluated concept of new lensing process for NPI transducers via choosing the proper epoxy and mold design and process steps. Finally, the proposed lensing process passed all verification and reliability tests required based on medical device industries and FDA regulations. 2 P a g e

Analyzed debond failures in acoustic functional layers in a new transducer product via mercury porosimetry intrusion and X-Ray CT techniques and detected and proved the rootcause of the failure. Eventually, suggested the practical solutions such as initial porosimetry measurements of raw materials before production. Northeastern University, Boston, MA
