WebThe warpage can be controlled with a thicker substrate, but this increases the package thickness. The concept of strip grinding is to grind the mold compound and die together. The advantage of strip grinding is to use normal die thickness and mold cap thickness, thus reducing the risk of thin die handling and narrow mold clearance.
