Abstract

A module includes an electronic component, an enclosure at least partially enclosing the electronic component and defining a module interface at which the module is configured to be mounted on a mounting base, and a gas flow-inhibiting sealing at the module interface and configured to inhibit gas from propagating from an exterior of the module towards the electronic component. An electronic device that includes the module and a method of manufacturing the module are also described.

Claims (47)

1. A module, comprising:

an electronic component;

an enclosure at least partially enclosing the electronic component and defining a module interface at which the module is configured to be mounted on a mounting base; and

a gas flow-inhibiting sealing at the module interface and configured to inhibit gas from propagating from an exterior of the module towards the electronic component,

wherein the gas flow-inhibiting sealing is made of a compressible material.

2. The module of claim 1 , wherein the enclosure comprises an encapsulant at least partially encapsulating the electronic component with physical contact.

3. The module of claim 1 , wherein the enclosure comprises a housing accommodating the electronic component.

4. The module of claim 3 , wherein the housing defines the module interface.

5. The module of claim 1 , wherein the gas flow-inhibiting sealing has a substantially annular shape.

6. The module of claim 5 , wherein the substantially annular shape is a closed ring or an open ring.

7. The module of claim 1 , wherein the compressible material is a foam.

8. The module of claim 1 , further comprising a carrier that carries the electronic component.

9. The module of claim 8 , further comprising a further gas flow-inhibiting sealing between the carrier and the enclosure.

10. The module of claim 1 , wherein at least one of:

the gas flow-inhibiting sealing comprises a gas-diffusion inhibiting material;

the gas flow-inhibiting sealing comprises sacrificial particles configured to consume corrosive gas;

the electronic component has at least one pad made of a corrodible material being corrodible by the corrosive gas;

electrically conductive needles electrically couple the electronic component with an exterior of the module; and

the electronic component is a power semiconductor chip.

11. The module of claim 1 , wherein the gas flow-inhibiting sealing is a gas flow-tight sealing.

12. A module, comprising:

an electronic component;

an enclosure at least partially enclosing the electronic component and defining a module interface at which the module is configured to be mounted on a mounting base; and

a gas flow-inhibiting sealing at the module interface and configured to inhibit gas from propagating from an exterior of the module towards the electronic component,

wherein the gas flow-inhibiting sealing is made of an elastic material.

13. The module of claim 12 , wherein the elastic material is a Shore 00 material, a Shore A material, or a Shore D material below 35.

14. A module, comprising:

an electronic component;

an enclosure at least partially enclosing the electronic component and defining a module interface at which the module is configured to be mounted on a mounting base;

a gas flow-inhibiting sealing at the module interface and configured to inhibit gas from propagating from an exterior of the module towards the electronic component;

a carrier that carries the electronic component; and

a further gas flow-inhibiting sealing between the carrier and the enclosure.

15. A module, comprising:

an electronic component;

an enclosure at least partially enclosing the electronic component and defining a module interface at which the module is configured to be mounted on a mounting base; and

a gas flow-inhibiting sealing at the module interface and configured to inhibit gas from propagating from an exterior of the module towards the electronic component,

wherein at least one of:

the gas flow-inhibiting sealing comprises a gas-diffusion inhibiting material;

the gas flow-inhibiting sealing comprises sacrificial particles configured to consume corrosive gas;

the electronic component has at least one pad made of a corrodible material being corrodible by the corrosive gas;

electrically conductive needles electrically couple the electronic component with an exterior of the module; and

the electronic component is a power semiconductor chip.

16. A module, comprising:

an electronic component;

an enclosure at least partially enclosing the electronic component and defining a module interface at which the module is configured to be mounted on a mounting base; and

a gas flow-inhibiting sealing at the module interface and configured to inhibit gas from propagating from an exterior of the module towards the electronic component,

wherein the gas flow-inhibiting sealing is a gas flow-tight sealing.
