Abstract:
A clamp for fixturing a substrate when forming and thermally processing upon the substrate a thermally flowable layer comprising:a backing member;a top member connected through a first mechanical means to the backing member, the backing member and the top member being sized such that a substrate may be clamped between the backing member and the top member, a portion of the top member overlapping the substrate and leaving exposed a first portion of the substrate when the substrate is clamped between the backing member and the top member; anda shroud connected through a second mechanical means to the backing member, a portion of the shroud overlapping the top member, the shroud leaving exposed a second portion of the substrate which is smaller than and contained within the first portion of the substrate, the shroud being removable from the backing member while the substrate remains clamped between the backing member and the top member.
