Lam Research Interview Question

GD&T basics : Flatness tolerance, cylindricity, circularity, etc. RSS method to calculate tolerance (basic tolerance analysis). Describe the heat distribution of a bar of length X attached to a heat source. Both the bar and the heat source are in space in a perfect vacuum condition. What affects the rate of heat transfer and what method would you use to bond the bar to the heat source for maximum heat transfer. Why? How would you go about choosing a bolt for an application. What factors do you look out for? Stress vs Strain curve for ductile and brittle materials Provided an image of a component and asked to describe the design process.
