Abstract
Abstract The produce comprises an electrically conductive tape cut out or etched so as to form windows from which connecting tabs for a chip project, according to the "single-layer" T.A.B. technology. An adhesive tape is glued to the conductive tape and pierced with windows centered on and lying within the conductive tape's windows. According to the invention, apertures isolate the connecting tabs for the purpose of applying test signals to the chip by means of the tabs then carried by the adhesive tape alone. The invention is used for testing integrated power circuits.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
165 words
A product in tape form for supporting and conveying electronic components staggered on the product, comprising a tape made of electrically conductive material and cut with a staggered series of windows, and electrical connection tabs cut out from the tape within each window, starting from the contour of the latter, these tabs each being associated with one of the outputs of an electronic component, characterized in that it comprises an electrically insulating adhesive piece applied to that face of the conductive tape not receiving the component, so as to adhere to said conductive tape and to the connection tabs at least in the vicinity of the contour of the window, said adhesive piece overlapping the window contour so as to lie both within and without the window and, at least one aperture passing through both the adhesive piece and the conductive tape in order to ensure the electrical insulation of at least one of said connection tabs without breaking its adherence to the adhesive piece.
Claim 2
Dependent Claim
165 words
A product in tape form for supporting and conveying electronic components staggered on the product, comprising a tape made of electrically conductive material and cut with a staggered series of windows, and electrical connection tabs cut out from the tape within each window, starting from the contour of the latter, these tabs each being associated with one of the outputs of an electronic component, characterized in that it comprises an electrically insulating adhesive piece applied to that face of the conductive tape not receiving the component, so as to adhere to said conductive tape and to the connection tabs at least in the vicinity of the contour of the window, said adhesive piece overlapping the window contour so as to lie both within and without the window and, at least one aperture passing through both the adhesive piece and the conductive tape in order to ensure the electrical insulation of at least one of said connection tabs without breaking its adherence to the adhesive piece.
Claim 3
Dependent Claim
53 words
The product as claimed in claim 1, wherein the adhesive piece is an adhesive tape cut with a succession of windows staggered at the same interval as those of the conductive tape, the contour of a window of the adhesive tape being within the contour of the associated window of the conductive tape.
Claim 4
Dependent Claim
30 words
The product as claimed in claim 2, wherein the contour of a window of the adhesive tape is parallel to the contour of the associated window of the conductive tape.
Claim 5
Dependent Claim
21 words
The product as claimed in claim 3, wherein the contours of two associated windows (3) and (8) are concentric and rectangular.
Claim 6
Dependent Claim
46 words
The product as claimed in claim 1, wherein the adhesive piece is an adhesive frame associated with each window of the conductive tape and fastened to the latter so as to project from the contour of the associated window on the inside and on the outside.
Claim 7
Dependent Claim
48 words
The product as claimed in claim 1, wherein the contour of the insulating aperture is set apart from the contour of the window of the adhesive piece, in such a way that a part of the associated connection tab is bonded to this tape between these two contours.
Claim 8
Dependent Claim
26 words
The product as claimed in claim 1, wherein the contour of the aperture is placed astride the contour of the window formed in the conductive tape.
Claim 9
Dependent Claim
43 words
The product as claimed in claim 1, characterized in that it possesses several apertures through both said adhesive piece and said conductive tape, pierced in such a way as to insulate each of several tabs from one another and from the conductive tape.
Claim 10
Dependent Claim
20 words
The product as claimed in claim 1, wherein the adhesive piece is composed of an unsupported film of adhesive product.
Claim 11
Dependent Claim
38 words
The product as claimed in claim 1, wherein the adhesive piece is formed round the window of the conductive tape by molding on an adhesive product within and on the outside of the contour of the said window.
Claim 12
Dependent Claim
21 words
The product as claimed in claim 1, wherein the electronic component is an integrated circuit in the form of a "chip".
Claim 13
Dependent Claim
54 words
The product as claimed in claim 1, characterized in that the conductive tape has rows of transport holes running along its lengthwise margins, said adhesive piece is a tape whose width is less than the lateral distance between said rows of transport holes, and said adhesive piece is disposed between said rows of holes.
