Abstract
Abstract A flexible, engineered, laminated polyfoam chip component carrier tape having a stable base layer member, a flexible expandable and compressible upper member layer, said two layers having appropriate sprocket holes and chip cavities formed therein, a bottom cover layer providing a base for said chip cavities, said bottom cover layer being heat sealable to the rigid base layer, and a controlled, creped thermally bonded and peelable top cover layer to retain the chip components in said tape until such time as they are presented to automatic placement equipment. The sprocket holes provide drive engagement integrally formed in said tape. Spaced recessed areas are formed in the carrier tape for receiving chip components. The use of one or more transparent plastic films on either the top or bottom cover layer provides optical verification of the presence or absence of components in each of the recessed areas after the carrier tape is loaded with components.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
84 words
A low cost, disposable, flexible engineered laminated polyfoam carrier tape for packaging leadless components for feeding said components to automatic component placement machines comprising: a stable base layer member of said laminated tape; at least one flexible, expandable and compressible upper member layer of said laminated tape; means to laminate said base layer and upper layer members to form a laminated tape structure; drive engaging means integrally formed in said laminated tape; and spaced recessed areas provided in said tape for receiving leadless components.
Claim 2
Dependent Claim
84 words
A low cost, disposable, flexible engineered laminated polyfoam carrier tape for packaging leadless components for feeding said components to automatic component placement machines comprising: a stable base layer member of said laminated tape; at least one flexible, expandable and compressible upper member layer of said laminated tape; means to laminate said base layer and upper layer members to form a laminated tape structure; drive engaging means integrally formed in said laminated tape; and spaced recessed areas provided in said tape for receiving leadless components.
Claim 3
Dependent Claim
30 words
The laminated polyfoam carrier tape of Claim 1, wherein said stable base layer is a sheet of strong chemically neutral paper and said drive engaging means are spaced sprocket holes.
Claim 4
Dependent Claim
35 words
The laminated polyfoam carrier tape of Claim 1, wherein: said flexible, expandable, and compressible member is a closed cell, cross-linked foam polyethylene; and said foam is laminated to said base member layer by thermal bonding.
Claim 5
Dependent Claim
18 words
The laminated polyfoam carrier tape of Claim 3, wherein said spaced recesses are formed in said foam only.
Claim 6
Dependent Claim
52 words
The laminated polyfoam carrier tape of Claim 4, wherein: each of said spaced recesses has a length and a width slightly less than the length and width of the components to be held therein and said components are forced fitted into said recesses and retained therein by the resiliency of said foam.
Claim 7
Dependent Claim
46 words
The laminated polyfoam carrier tape of Claim 1, further comprising: a flexible, expandable and compressible top cover tape dimensioned to cover the open tops of said spaced recesses without obstructing said tape drive engaging means, said top cover tape removably secured to said upper member layer.
Claim 8
Dependent Claim
36 words
The laminated polyfoam carrier tape of Claim 6, wherein said top cover tape is a creped polypropylene film and said top cover tape is peelably laminated and secured to said upper member layer by thermal bonding.
Claim 9
Dependent Claim
57 words
The laminated polyfoam carrier tape of Claim 1, wherein: said spaced recesses are holes formed in said upper member layer and said base member layer; and further comprising: a bottan cover tape secured to said base member layer; said bottom cover tape covering the base of each of said spaced recesses without obstructing said drive engaging means.
Claim 10
Dependent Claim
15 words
The laminated polyfoam carrier tape of Claim 8, wherein said bottom cover tape is transparent.
Claim 11
Dependent Claim
31 words
The laminated polyfoam carrier tape of Claim 9, wherein said bottom cover tape is a laminated clear plastic film , one of said layers being a thin heat softened plastic film.
Claim 12
Dependent Claim
30 words
The laminated polyfoam carrier tape of Claim 10, wherein said laminated clear plastic bottom cover tape is a lamination of a temperature resistant plastic film and lowermelt temperature plastic film.
Claim 13
Dependent Claim
30 words
The laminated polyfoam carrier tape of Claim 11, wherein each of said spaced recesses has a small hole formed through said bottom cover tape for use with a vacuum source.
Claim 14
Dependent Claim
78 words
The laminated polyfoam carrier tape of Claim 1, further including: a flexible, expandable and compressible top cover tape dimensioned to fit over said spaced recesses without obstructing said drive engaging means; said top cover tape being peelable from said upper member layer such that it may be peeled therefrom to yield access to said components by an automatic component placement machine without leaving a fragmentary residue; means to secure said top cover tape to said upper member layer.
Claim 15
Dependent Claim
38 words
A flexible, expandable and compressible removable top cover tape for a polyfoam carrier tape for holding leadless electronic components in spaced cavities comprising: a creped thin material randomly spot adhered around the periphery of the spaced component cavities.
Claim 16
Dependent Claim
38 words
A flexible, expandable and compressible removable top cover tape for a polyfoam carrier tape for holding leadless electronic components in spaced cavities comprising: a creped thin material randomly spot adhered around the periphery of the spaced component cavities.
Claim 17
Dependent Claim
14 words
The top cover tape of claim 14 wherein said creped material is polypropylene film.
Claim 18
Dependent Claim
21 words

Claim 19
Dependent Claim
50 words
The top cover tape of claim 16 wherein said top cover tape is adhered to said polyfoam by thermal bonding the lower tip of each flute of said creped polypropylene film such that small portion of the surface of said cover tape is peelably adhered to said polyfoam carrier tape.
Claim 20
Dependent Claim
13 words
The top cover tape of claim 14 wherein said creped material is paper.
Claim 21
Dependent Claim
39 words
The laminated polyfoam carrier tape of Claim 1, further including: means permitting the inspection of said recessed areas to determine the presence or absence of components in each of said recessed areas after said tape is loaded with components.
