Abstract:
During a process to encapsulate electronic components and attachment interfaces thereof on a first side of a substrate of a hybrid assembly, a fluid is supplied to a trench of an encapsulation system in which the hybrid assembly is loaded, and a balancing pressure is delivered by the fluid within the trench, during the encapsulation process, to support the hybrid assembly from an opposing second side of the substrate. A regulator of a fluid supply of the system may maintain the balancing pressure, for example, being controlled by a controller of the system that is configured to estimate a pressure within a molding cavity of the system.
