Wafer Chip Scale Package WCSP leads are Ball Grid Array BGA balls processed directly onto the die Heat from the BGA balls are directly transferred to the die instead of transferring over the pins or through a die attach pad as shown in Figure 3 Generally this is the package type with the fastest thermal
The first step in a free roofing estimate is measuring the roof dimensions You will need to express this size in terms of square feet Keep in mind that the average size of a roof is 1700 square feet so your total will likely be 10 higher or lower than this figure
approximation for steel weight per square foot in a braced building using steel with Fy 50 ksi is Wtpsf stories3 7 A threestory building would have a steel weight in the range of 8 psf and a 27story building would require 16 psf Certainly this relationship is an over simplification Yet it provides a value
