Problems solved by technology

While such solutions offer benefits in certain applications, the chip's input / output (I / O) terminals can be very small and it becomes a challenge to precisely make such connections
Also, the finished device may not successfully pass the burn-in test, thus negating all previous efforts
[0019] Another area of ​​concern is thermal management, since densely packed ICs produce high energy densities that reduce the reliability of electronics

Embodiment Construction

[0088] In the following description and accompanying drawings, specific terms and reference numerals are explained in detail to provide a thorough understanding of the present invention. In some instances, the terms and labels may contain specific details not required to practice the invention. For example, an interconnect between conductor elements of a component (i.e., an I / O lead of a component) may be shown or described as having multiple conductors interconnected to one lead or connected to multiple component contacts within or between devices. A conductor signal line. Thus, each of the plurality of conductor interconnections may alternatively be a signal, control, power or ground line of one conductor, and vice versa. Circuit paths shown or described as single-ended may also be different, and vice versa. Interconnect assemblies can consist of standard interconnects; microstrip or stripline interconnects and all signal lines of the assembly can be shielded or unshielded...

Abstract

Provided is an electronic assembly 400 and a method for its manufacture 800, 900, 1000 1200, 1400, 1500, 1700. The assembly 400 uses no solder. Components 406, or component packages 402, 802, 804, 806with I / O leads 412 are placed 800 onto a planar substrate 808. The assembly is encapsulated 900 with electrically insulating material 908 with vias 420, 1002 formed or drilled 1000 through the substrate 808 to the components' leads 412. Then the assembly is plated 1200 and the encapsulation and drilling process 1500 repeated to build up desired layers 422, 1502, 1702. The planar substrate 808 maybe a flexible substrate 2016 allowing bending of an assembly 2000 to fit into various enclosures.
