## Abstract

An assembly suitable for housing electronic components can include a top shield and a bottom shield, the bottom shield having a conductive outer cover, a wall section, and a laminating portion between the conductive outer cover and the wall section. The laminating portion may include laminating material. A printed circuit board (PCB) may be positioned between the top shield and the bottom shield.

## Claims

### Claim 1

An assembly suitable for housing electronic components, the assembly comprising:
a top shield;
a bottom shield coupled with the top shield, the bottom shield including:
a conductive outer cover;
a wall section; and
a laminating portion between the conductive outer cover and the wall section, the laminating portion comprising laminating material that substantially covers a surface of the conductive outer cover;
a printed circuit board (PCB) positioned between the top shield and the bottom shield; and
at least one mechanical hardware component configured to provide proper spacing between the wall section of the bottom shield and the PCB.

### Claim 2 (depends on 1)

The assembly of claim 1, wherein the wall section is a conductive punched wall section.

### Claim 3 (depends on 1)

The assembly of claim 1, wherein the conductive outer cover is made of punched aluminum.

### Claim 4 (depends on 1)

The assembly of claim 1, wherein the wall section is constructed from aluminum.

### Claim 5 (depends on 1)

The assembly of claim 1, wherein the laminating material includes at least one from a group consisting of: double-sided conductive adhesive, aluminum solder paste, aluminum solder preforms, conductive epoxy, and sheet gasket with double-sided adhesive.

### Claim 6 (depends on 1)

The assembly of claim 1, further comprising at least one mechanical fastener configured to trap a gasket or gasket-like material between the conductive outer cover and the wall section.

### Claim 7 (depends on 6)

The assembly of claim 6, wherein the at least one mechanical fastener includes at least one from a group consisting of: rivets, spot welds, screws, and PEM hardware.

### Claim 8 (depends on 6)

The assembly of claim 6, wherein gasket-like material includes at least one from a group consisting of: dimpled sheet gasket, woven screen, sheet gasket, and dielectric absorber.

### Claim 9 (depends on 1)

The assembly of claim 1, wherein the wall section includes at least one clearance cavity punched therein to provide extra space for at least one component on the PCB.
