Abstract
Electronic device package technology is disclosed. In one example, an electronic device package can include a substrate, an electronic component disposed on the substrate and electrically coupled to the substrate, and an underfill material disposed at least partially between the electronic component and the substrate. A lateral portion of the underfill material can comprises a lateral surface extending away from the substrate and a meniscus surface extending between the lateral surface and the electronic component.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A method for making an electronic device package, comprising:
disposing an electronic component on a substrate, such that the electronic component is electrically coupled to the substrate; forming a barrier with a sacrificial material about at least a portion of the electronic component; disposing an underfill material at least partially between the electronic component and the substrate, wherein flow of the underfill material is mechanically inhibited at least partially by the barrier; and removing the barrier.
2 . The method of claim 1 , wherein forming the barrier comprises dispensing the sacrificial material on the substrate.
3 . The method of claim 1 , wherein forming the barrier comprises printing the sacrificial material on the substrate.
4 . The method of claim 3 , wherein printing the sacrificial material on the substrate comprises disposing a stencil about the substrate, the stencil having an aperture corresponding to a location of the barrier.
5 . The method of claim 4 , wherein printing the sacrificial material on the substrate further comprises causing the sacrificial material to pass through the aperture and onto the substrate.
6 . The method of claim 5 , wherein printing the sacrificial material on the substrate further comprises removing the stencil.
7 . The method of claim 5 , wherein printing the sacrificial material on the substrate further comprises drying the sacrificial material.
8 . The method of claim 1 , wherein removing the barrier comprises heating the sacrificial material.
9 . The method of claim 8 , wherein the sacrificial material is thermally decomposed.
10 . The method of claim 1 , wherein removing the barrier comprises dissolving the sacrificial material.
11 . The method of claim 10 , wherein the sacrificial material is water soluble.
12 . A method for making an electronic device package, comprising:
obtaining a substrate having an electronic component region, and a sacrificial material on the substrate forming a barrier about at least a portion of the electronic component region; disposing an electronic component on a substrate in the electronic component region, such that the electronic component is electrically coupled to the substrate; disposing an underfill material at least partially between the electronic component and the substrate, wherein flow of the underfill material is mechanically inhibited at least partially by the barrier; and removing the barrier.
13 . The method of claim 12 , wherein removing the barrier comprises heating the sacrificial material.
14 . The method of claim 13 , wherein the sacrificial material is thermally decomposed.
15 . The method of claim 12 , wherein removing the barrier comprises dissolving the sacrificial material.
16 . The method of claim 15 , wherein the sacrificial material is water soluble.
17 . A method for facilitating an underfill material keep out zone (KOZ) of an electronic component, comprising:
obtaining a substrate having an electronic component region; and disposing a sacrificial material on the substrate to form a barrier about at least a portion of the electronic component region to mechanically inhibit flow of an underfill material.
18 . The method of claim 17 , wherein disposing a sacrificial material on the substrate comprises dispensing the sacrificial material on the substrate.
19 . The method of claim 17 , wherein disposing a sacrificial material on the substrate comprises printing the sacrificial material on the substrate.
20 . The method of claim 19 , wherein printing the sacrificial material on the substrate comprises disposing a stencil about the substrate, the stencil having an aperture corresponding to a location of the barrier.
21 . The method of claim 20 , wherein printing the sacrificial material on the substrate further comprises causing the sacrificial material to pass through the aperture and onto the substrate.
22 . The method of claim 21 , wherein printing the sacrificial material on the substrate further comprises removing the stencil.
23 . The method of claim 21 , wherein printing the sacrificial material on the substrate further comprises drying the sacrificial material.
24 . The method of claim 17 , wherein the sacrificial material is thermally decomposable.
25 . The method of claim 17 , wherein the sacrificial material is water soluble.Join the waitlist — get patent alerts
