Abstract
An injection mould and an injection moulding method are provided. The injection mould includes a base plate used to place a packaged chip to be injection moulded including a substrate and at least one of the chips fixed on the front substrate by a flip chip process. The substrate has a gas hole. Two or more gas ducts that extend in at least two intersected directions and connect with one another are formed in the base plate. Two ends of each one of gas ducts are open, and at least one of the gas ducts is buried into the base plate. Each one of gas ducts is provided with a gas outlet. When the packaged chip is placed on the base plate, the gas outlet connects with the gas hole of the substrate.
Claims13
An injection mould, comprising,
- a base plate used to place a packaged chip to be injection moulded, wherein the packaged chip comprises a substrate and at least one chip fixed on a front surface of the substrate by a flip chip process, and the substrate has a gas hole penetrating through the substrate;
- wherein two or more gas ducts that extend in at least two intersecting directions and connect with one another are formed in the base plate;
- two ends of each one of the two or more gas ducts are open and connect to an exterior of the injection mould, at least one of the two or more gas ducts is buried into the base plate, and in a direction perpendicular to a surface of the base plate, the two or more gas ducts that extend in the at least two intersecting directions are respectively located at different depths in the base plate;
- and
- wherein each of the two or more gas ducts is provided with a gas outlet used to connect with the gas hole penetrating through the substrate, and the gas outlet is located at an intersection of different gas ducts of the two or more gas ducts, so that the intersected gas ducts connect with one another.
