Abstract:
A method of assembling the microelectronic device assembly that includes:a microelectronic component having a facing surface that carries a first terminal array; a first support having a component surface, a second terminal array carried on the component surface and electrically coupled to the first terminal array, and an elongate aperture extending through a thickness of the support and having a first dimension and a second dimension less than the first dimension, the component surface of the support being juxtaposed with the facing surface of the microelectronic component to define an underfill gap between the component surface and the facing surface; and an underfill material substantially filling the underfill gap; the method comprising: juxtaposing the facing surface with the component surface and electrically coupling terminals of the first terminal array with terminals of the second terminal array, the facing surface and the component surface being spaced from one another to define the first underfill gap; placing a stencil adjacent the exterior surface of the support, the stencil having a stencil opening in registry with the elongate aperture through the support, thereby defining an outwardly-open volume for receiving underfill material; filling the outwardly-open volume with the first underfill material; allowing the first underfill material to flow into and substantially fill the first underfill gap; and removing the stencil.
