Product Development Interview Questions

3,725 product development interview questions shared by candidates

Fourier's law of heat conduction? Diffusivity? If you want to dissipate heat faster what kind of materials would you choose? There were a lot of heat transfer-related questions in conjunction with materials? (read about the chip manufacturing process) If two metal strips of different thermal expansion coefficients are bonded together (one on top of the other) and heated, how would the resulting shape be and which material has a higher stress concentration?
