Abstract
Abstract A fixture for supporting integrated circuit packages during wave soldering of leads on the packages includes a carrier portion including two sets of orthogonal support members. The support members have formed edges for defining seats for receiving the packages. A frame cover includes appendages for engaging the packages and maintaining the packages in the seats. The arrangement of the orthogonal support members and cover appendages facilitates solder wave access to all leads of the packages and cleaning and drying of the packages. Heat transfer from the molten solder during the wave soldering procedure is minimized due to the low mass of the cover appendages.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
83 words
A fixture for supporting packages during wave soldering of leads on the packages comprising a carrier portion including two sets of orthogonal support members, said orthogonal support members having formed edges defining seats for receiving the packages, and a frame cover pivotally attached to said carrier portion for retaining packages in said seats when said fixture is turned upside down, said frame cover including appendages extending therefrom for engaging packages, said support members having notches in said edges for receiving said frame cover.
Claim 2
Dependent Claim
83 words
A fixture for supporting packages during wave soldering of leads on the packages comprising a carrier portion including two sets of orthogonal support members, said orthogonal support members having formed edges defining seats for receiving the packages, and a frame cover pivotally attached to said carrier portion for retaining packages in said seats when said fixture is turned upside down, said frame cover including appendages extending therefrom for engaging packages, said support members having notches in said edges for receiving said frame cover.
Claim 3
Dependent Claim
26 words
The fixture as defined in claim 1 wherein edges of said support members include slots whereby said slots of said two orthogonal support members are engaged.
Claim 4
Dependent Claim
34 words
The fixture as defined in claim 2 wherein said slots are selectively positioned in opposing edges of at least one set of said support members whereby said orthogonal support members form an interlocked assembly.
Claim 5
Dependent Claim
35 words
