A device (100) may include an electrical assembly (102) having at least one electrical component; an inner shell (108) comprising a first polymeric material conformally disposed around the electrical component, the inner shell (108) comprising a first mechanical strength; and an outer shell (110) comprising a second polymeric material conformally disposed around the inner shell (108), the outer shell (110) comprising a second mechanical strength greater than the first mechanical strength, wherein the electrical component comprises a first coefficient of thermal expansion (CTE), the inner shell (108) comprises a second CTE, and the outer shell (110) comprises a third CTE, and wherein a difference between the first CTE and second CTE is less than a difference between the first CTE and third CTE. |
