Electronic assembly having a substrate laminated within a backplate cavity

1. A lamination apparatus, comprising:

a frame including a base;

a linear motion device attached to the frame opposite the base;

a ram coupled to an end of the linear motion device, the ram including at least one air passage that provides an air evacuation path when the ram is working on a workpiece;

a first elastomer attached to the ram attached only to a central portion of the ram, wherein the first elastomer functions as a plunger;

a second elastomer attached to the ram, wherein the second elastomer contacts and covers the first elastomer such that an air gap is formed between the ram and second elastomer, and wherein the second elastomer has a convex outer surface; and

wherein compressed air located between the ram and the second elastomer escapes though the evacuation path when the linear motion device is in an extended state.

2. The apparatus of claim 1 , wherein the workpiece is an electronic assembly, and wherein the workpiece comprises:

a backplate including a cavity;

a substrate including a plurality of interconnected electrical components, wherein the substrate is positioned within the cavity; and

an adhesive bonding the substrate to the backplate, wherein the adhesive is pressure sensitive adhesive (PSA), and wherein a wall height of the cavity is greater than a combined thickness of the adhesive and the substrate.

3. The apparatus of claim 2 , wherein the substrate is a printed circuit board (PCB).

4. The apparatus of claim 2 , wherein the backplate functions as a portion of a product enclosure.

5. The apparatus of claim 4 , wherein the substrate is a printed circuit board (PCB).

6. The apparatus of claim 2 , wherein the substrate is a ceramic substrate.

7. The apparatus of claim 2 , wherein the backplate is made of a metal.

8. The apparatus of claim 7 , wherein the metal is aluminum.
