Component for reducing mechanical stress on a PCB

An assembly comprising:

• an electronics component arranged on a second component,
• said second component mounting the assembly on a printed circuit board (PCB),
• said second component having an extension in each of the longitudinal, lateral and vertical directions with reference to how the assembly mounted on the PCB,
• the second component also having a first main surface and a second main surface, wherein said electronics component is mounted in direct contact on said first main surface, and wherein said second main surface is mounted on a main surface of the PCB,
• wherein the second component is made in a non conducting material, with a first layer of conducting material arranged on at least part of said first main surface of the second component, said first conducting layer being connected to a second conducting layer on the second main surface of the second component by electrically conducting means,
• wherein the second component exhibits a through-going aperture from the first main surface to the second main surface, such that the area of the aperture is larger than the area of the first main surface,
• wherein the second component exhibits a greater flexibility than the electronics component in the vertical direction and one direction perpendicularly across the assembly;
• wherein the second component flexes in at least one of the lateral, longitudinal, and vertical directions in response to at least one of contractions, expansions, and shock in the PCB, said flexing preventing damage to the electronics component;
• and
• wherein the sides of the second component extending in the longitudinal direction exhibit a “waist”, such that a shortest lateral distance across the component at a first point is smaller than a shortest distance across the component at a second point between said first point and a longitudinal end of the component.
