This makes Rubalit ® 708 HP ideal for power electronics in conjunction with direct copper bonding (DCB) and active metal brazing (AMB). Since P-SoXS only measures in plane structure, this indicates that polymer crystallites take the opposite orientation of the polymer probed by the P-SoXS measurement. 2, for generality the two substrates have thicknesses h 1 and h 2 and the solder layer has thickness t and joint length L. ISOPLUS package, the die is attached to the DCB ceramic substrate, and CTE mismatch between the die and substrate is much less than between die and copper.
