The overall height of the tallest package mounted on the PCB, often the PoP, becomes the major factor that dictates product design thickness
many engineers have been reluctant to revise the current design thickness
Frozen wall was designed according to frozen powder sand strength for the corridor located in powder sand layer ,and a design thickness
Layers of composites am built up according to a specific design thickness
, in this case 16mm to restore the pressure and structural integrity of the line.
When the thickness of any finite element of the preform is reduced further from the minimum uniform preform thickness, a blow-molded part is produced that has regions where part thicknesses are thinner than the minimum design thickness
The actual design thickness
can vary according to test results from soil samples.
Resin-impregnated sheets of carbon fiber are then built up to a specified design thickness
needed to restore full pressure containment.
