Abstract

Abstract A magnet is disposed in proximity to an un-lidded semiconductor package being assembled. When a ferrous lid is placed over the package opening, the magnetic field holds the lid in place, and also holds the package on an assembly boat carrying the package through an oven for hermetic sealing.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 71 words
Composite boat transport for supporting semiconductor packages during assembly, comprising: a planar platform member having a top surface and a support area on the top surface for supporting a semiconductor package body; a loader member having a top surface for supporting the planar platform member; and a magnet mounted to the loader member at a location where the magnet will exert a force holding a lid onto the semiconductor package body.
Claim 2
Dependent Claim 71 words
Composite boat transport for supporting semiconductor packages during assembly, comprising: a planar platform member having a top surface and a support area on the top surface for supporting a semiconductor package body; a loader member having a top surface for supporting the planar platform member; and a magnet mounted to the loader member at a location where the magnet will exert a force holding a lid onto the semiconductor package body.
Claim 3
Dependent Claim 24 words
Composite boat transport according to claim 1, wherein: the magnet is of sufficient strength to hold the package body securely on the platform member.
Claim 4
Dependent Claim 26 words
Composite boat transport according to claim 1, further comprising: pins extending from the top surface of the loader; and corresponding holes through the planar platform member.
Claim 5
Dependent Claim 61 words
Composite boat transport according to claim 1, wherein: the platform member has an opening in the support area allowing automated equipment to lift the package body up off of the platform member; the loader member has a corresponding opening in an area aligned with the support area; and at least one magnet is disposed about the opening in the loader member.
Claim 6
Dependent Claim 43 words
Boat transport for supporting semiconductor packages during assembly, comprising: a platform having a top surface and an area for supporting a semiconductor package body; and a magnet associated with the platform for exerting a force holding a lid onto the semiconductor package body.
Claim 7
Dependent Claim 43 words
Boat transport for supporting semiconductor packages during assembly, comprising: a platform having a top surface and an area for supporting a semiconductor package body; and a magnet associated with the platform for exerting a force holding a lid onto the semiconductor package body.
