ABSTRACT:
A method of providing a predetermined set distance apart between two members in article manufacture. This involves clamping the members together with a mixture of an adhesive and glass microspheres between opposing surfaces of the members, the microspheres being of specific grid size. The largest diameter microspheres are gripped between the opposing surfaces thereby determining the distance between the members. The invention is particularly useful for precise location apart between members with small gaps therebetween, e.g. less than 3 mil. It is useful particularly for magnetic device cores of small dimensions.
