Abstract
A lid is sealed to an integrated circuit package by a method that uses a spring biased pressure foot that is structurally carried by a secondary loading jig to impose sealant curing load on the lid. The pressure foot is retracted against the spring bias while secondary jig index pins are meshed with corresponding sockets in the fabrication boat that are aligned with the package position on the boat. When the pins and sockets are meshed, the pressure foot is released to apply optimal assembly force at the package center normal of the package lid plane.
Claims13
A method of applying a resilient force bias along a loading axis substantially central of and perpendicular to a package lid on an integrated circuit while, said package lid and said integrated circuit confined in an alignment socket respective to an assembly boat, said method comprising the steps of retracting a resilient force biased pressure foot confined within a loading jig from a package lid engagement position, said loading jig having a first index structure that corresponds with a second index structure integral with said assembly boat, meshing said first index structure with said second index structure to align said pressure foot with said loading axis and releasing said pressure foot to resiliently bear against the substantial center of said package lid and substantially normal thereto.
A method of packaging an integrated circuit comprising the steps of positioning an integrated circuit containing a package base in an alignment socket element of an assembly boat, positioning a substantially planar lid element over said package base, securing a loading jig to said assembly boat in structurally confined alignment with said alignment socket, rotating a pressure foot about a rotational axis secured to said loading jig and resiliently biasing said pressure foot rotation against said lid element.
