The Materials and Surface Engineering section of the Department of Mechanical Engineering at the Technical University of Denmark is seeking candidate for 1 PhD position in the field of “Humidity effects on electronics” focusing on understanding the PCBA design related factors and humidity interaction resulting in corrosion reliability issues. This PhD position for 3 years and part of the large consortium project ELMAC (Electronics manufactured for climate). Position is expected to start from September 1st 2020.
Today electronic devices get exposed to varying climatic conditions due their widespread applications. Uncontrolled humidity entry to the devise and thin water film formation on interior parts such as Printed Circuit Board Assemblies (PCBAs) can result in various corrosion failure modes. The formation, thickness, and electrolytic nature of the water film greatly depend on the nature of the PCBA surface, design, and cleanliness aspects.
Responsibilities and tasks
The intended PhD projects will focus on understanding the relationship between thin water film build up on PCBA surface and resulting corrosion/electrochemical process as a function of various PCBA parameters. The idea is to understand how various PCBA design elements influence failures caused by humidity, and understanding failure possibilities from humidity measurements. Work will involve the use of electrochemical methods such as DC polarization methods, electrochemical impedance spectroscopy, and local electrochemical methods.
Candidates should have a two-year master's degree (120 ECTS points) in materials science and engineering or chemistry or related subjects such as corrosion science and engineering. Prior experience on corrosion of electronics or similar topics is an advantage. Combination of knowledge in electronics, materials, corrosion, and reliability is preferred.
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide .
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice.
