Abstract
Abstract A large integrated circuit package is dropped into a housing that is attached to a printed circuit board in particular alignment with lead terminals on said board. Leads from the package are applied to the lead terminals when the package is properly positioned in the housing. A securing device having individual cams is moved into a position where it is assembled to the board and receiving means for applying camming pressure against said leads and lead terminals. The leads so engage the lead terminals that they are held against lateral movement during the camming action.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
In a combination of the class described, a circuit board having a plurality of lead terminals formed of relatively soft metal, a circuit package such as a large integrated circuit having a plurality of leads to be matched to and secured effectively to said lead terminals, circuit package receiving means on said circuit board into which said circuit package is deposited for effective alignment of its plurality of leads with said lead terminals, securing means movable relatively to said circuit board and said receiving means, guide means fixed relatively to said board and spaced therefrom, said securing means having guide surfaces engaging both said guide means and said board for guiding said securing means into a position functionally between said guide means and board in which it is held assembled to said board and said guide means through said guide surfaces, said securing means including individual cam shaped spring means exerting pressure individually against each of said lead terminals and said plurality of leads when said securing means is so held assembled to said guide means and said board.
Claim 2
Dependent Claim
179 words
In a combination of the class described, a circuit board having a plurality of lead terminals formed of relatively soft metal, a circuit package such as a large integrated circuit having a plurality of leads to be matched to and secured effectively to said lead terminals, circuit package receiving means on said circuit board into which said circuit package is deposited for effective alignment of its plurality of leads with said lead terminals, securing means movable relatively to said circuit board and said receiving means, guide means fixed relatively to said board and spaced therefrom, said securing means having guide surfaces engaging both said guide means and said board for guiding said securing means into a position functionally between said guide means and board in which it is held assembled to said board and said guide means through said guide surfaces, said securing means including individual cam shaped spring means exerting pressure individually against each of said lead terminals and said plurality of leads when said securing means is so held assembled to said guide means and said board.
Claim 3
Dependent Claim
32 words
In the combination of claim 1, the feature that said circuit package is freely deposited in said package receiving means and is secured to said board only through said plurality of leads.
Claim 4
Dependent Claim
46 words
In the combination of claim 1, the feature that said integrated circuit package receiving means has a flange or the like overlying said board and its plurality of lead terminals, and said securing means being adapted for movement into a position between said flange and board.
Claim 5
Dependent Claim
127 words
In the combination of claim 3, the feature that said circuit package receiving means has a series of slots into which said circuit package leads are placed as said package is deposited in said receiving means, said securing means having also a series of slots formed in accordance with the slots in said circuit package receiving means for alignment therewith, said parts of said securing means comprising a cam housed in each of said slots in said securing means for pressing said leads and terminals toward one another and to hold them in pressure relation thereafter, said cams moving in effective alignment with said leads and terminals through guidance by said guide means and board of said securing means into a position between said flange and board.
Claim 6
Dependent Claim
112 words
In the combination of claim 1, the feature that said integrated circuit package receiving means has a series of slots into which sAid circuit package leads are placed as said package is deposited in said receiving means, said securing means having also a series of slots formed in accordance with the slots in said circuit package receiving means for alignment therewith, said cam shaped springs being disposed within each of said slots in said securing means for pressing said leads and terminals toward one another and to hold them in pressure relation thereafter, said cams moving in effective alignment with said leads and terminals through guidance by said board and guide means.
Claim 7
Dependent Claim
28 words
In the combination of claim 1, the feature that said leads are formed with relatively sharp portions to be embedded in said lead terminals by said cam means.
Claim 8
Dependent Claim
32 words
In the combination of claim 1, the feature that said securing means is a body that is held bodily against the board by said receiving means when guided to its assembled position.
Claim 9
Dependent Claim
158 words
In a combination of the class described, a circuit board having a plurality of lead terminals, a circuit package such as a large integrated circuit package having a plurality of leads to be matched to and secured effectively to said lead terminals, circuit package receiving means on said circuit board into which said circuit package is deposited for effective alignment of its plurality of leads with said lead terminals, a flange or the like overlying portions of the said aligned leads and lead terminals and said board at a side of said receiving means, securing means adapted to move into position under said flange and over said leads and lead terminals, and parts of said securing means operative when said securing means is under said flange for pressing said leads against the lead terminals with which they are aligned, said flange or the like accepting the reaction of the pressure exerted by said parts of said securing means.
Claim 10
Dependent Claim
158 words
In a combination of the class described, a circuit board having a plurality of lead terminals, a circuit package such as a large integrated circuit package having a plurality of leads to be matched to and secured effectively to said lead terminals, circuit package receiving means on said circuit board into which said circuit package is deposited for effective alignment of its plurality of leads with said lead terminals, a flange or the like overlying portions of the said aligned leads and lead terminals and said board at a side of said receiving means, securing means adapted to move into position under said flange and over said leads and lead terminals, and parts of said securing means operative when said securing means is under said flange for pressing said leads against the lead terminals with which they are aligned, said flange or the like accepting the reaction of the pressure exerted by said parts of said securing means.
