Embodiment Construction

[0019] Various embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments are shown. Many different forms may be embodied and the described embodiments should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope to those skilled in the art.

[0020] exist figure 1 An example electronic package is shown generally at 10 in . As illustrated, electronic package 10 is formed as a ball grid array electronic package. Other package designs can be used, including land grid array, dual in-line package (DIP), quad flat pack (QFP), or flip chip. Electronic package 10 includes a dielectric substrate 12 having a first surface 12a and a second surface 12b and includes one or more conductive layers, vias, or coated vias for interconnection, as is well known in the art. A metalliza...

Abstract

An electronic package includes a substrate having opposing first and second surfaces. Conductive areas are on a first surface of the substrate and include at least one edge conductive area. A plurality of conductive bumps are on the second surface of the substrate and coupled to respective ones of the conductive areas. An integrated circuit (IC) is carried by the substrate. Bond wires are coupled between the IC and respective ones of the conductive areas. An encapsulating material is over the IC and adjacent portions of the substrate. A conductive layer is on the encapsulating material, and at least one conductive body is coupled between the at least one edge conductive area and the conductive layer.

Description

technical field [0001] The present disclosure relates to electronic packages, and more particularly, the present disclosure relates to an electronic package having a conductive layer on an encapsulation material for electromagnetic interference (EMI) shielding. Background technique [0002] Electronic devices often use electromagnetic interference (EMI) shielding to prevent damage to their performance caused by electromagnetic fields present in the operating environment. Some electronic devices contain a metal container or "can" that surrounds the electronic device to form an electromagnetic shield, the metal container or "can" being electrically connected to ground in the device. This shielding attenuates the EMI fields before they reach the device. Other EMI isolation systems use metal plates that fit over board-mounted electronics. Packaged electronic devices including integrated circuits (ICs), such as ball grid array (BGA) electronic packages, may include a metal film...
