Electromagnetic interference (emi) shielding apparatus and related methods

A method of making an electromagnetic interference (EMI) shielding having first and second walls in which a juncture between the first and second walls is substantially sealed for inhibiting ingress and/or egress of EMI through the juncture, the method comprising:

• positioning the second wall relative to the first wall such that an edge portion of the second wall is engaged generally between and laterally confined by laterally spaced-apart detent protrusions on the first wall, the laterally spaced-apart detent protrusions inhibiting movement of the second wall relative to the first wall, thereby helping retain the substantially sealed juncture between the first and second walls.

A method of retaining a closed seam between first and second walls of a shielding apparatus for inhibiting ingress and/or egress of electromagnetic interference (EMI) through the closed seam, the method comprising:

• positioning the second wall relative to the first wall such that an edge portion of the second wall is engaged generally between and laterally confined by laterally spaced-apart detent protrusions on the first wall, the laterally spaced-apart detent protrusions inhibiting movement of the second wall relative to the first wall, thereby helping the closed seam between the first and second walls remain closed.

A method relating to providing EMI shielding for one or more electrical components on a substrate, the method comprising:

• installing a shielding apparatus to a substrate such that outer walls of the shielding apparatus are disposed generally about one or more electrical components on the substrate, at least one of said outer walls having laterally spaced-apart detent protrusions, the shielding apparatus including at least one internal wall having an edge portion engaged generally between and laterally confined by laterally spaced-apart detent protrusions on at least one of said outer walls, such that the laterally spaced-apart detent protrusions inhibit movement of the at least one internal wall relative to the at leas one outer wall.
