Abstract:
A method of molding a circuit may include depositing a first epoxy mold compound (EMC) over a cavity, upon the first EMC gelling over a predetermined period of time, depositing a second EMC over the first EMC, and depositing a circuit in at least one of the first and second epoxy mold compounds. A circuit package may include a packaging and a circuit device in the packaging, wherein the packaging comprises a first EMC with a first CTE and a second EMC with a second CTE higher than the first CTE, the second EMC being dispensed onto the first EMC after the first EMC is allowed to gel to a predetermined degree.
