摘要：
A method of packaging a pressure sensor die includes providing a lead frame having a die pad and lead fingers that surround the die pad. A tape is attached to a first side of the lead frame. A pressure sensor die is attached to the die pad on a second side of the lead frame and bond pads of the die are connected to the lead fingers. An encapsulant is dispensed onto the second side of the lead frame and covers the lead fingers and the electrical connections thereto. A gel is dispensed onto a top surface of the die and covers the die bond pads and the electrical connections thereto. A lid is attached to the lead frame and covers the die and the gel, and sides of the lid penetrate the encapsulant.
