  • Method of hermetically encapsulating a crystal oscillator using a thermoplastic shell
    Patent number: 5640746
    Abstract: A method of hermetically encapsulating a crystal oscillator using a thermoplastic shell. A first step (102) includes molding a thermoplastic shell defining a cavity around a periphery of oscillator locations on a lead frame. A second step (104) includes attaching oscillator components including a piezoelectric element, capacitors and an integrated circuit to the lead frame. A third step (106) includes dispensing an encapsulant within the cavity defined by the thermoplastic shell to encapsulate the oscillator components. A fourth step (108) includes curing the encapsulant. A last step (110) includes excising the oscillator from the lead frame and the leads are formed for mounting.
