Abstract
Abstract A cover tape for sealing chips in chip-holding parts of a carrier tape having said parts provided discontinuously and longitudinally of said carrier tape, which cover tape comprises a base tape, an adhesive layer formed on one surface of said base tape and a non-adhesive coat formed on said adhesive layer along the longitudinal direction of said base tape so that said non-adhesive coat has a width broader than that of the chips and narrower than that of said adhesive layer. When the cover tape is used in combination with the carrier tape, the chip-holding parts are sealed by the cover tape having the non-adhesive coat and in consequence the chips held in the chip-holding parts do not come in contact with the adhesive layer although they might come in contact with the non-adhesive coat. Accordingly, the chips are not stained by the adhesive in the adhesive layer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
88 words
A cover tape for sealing chips in chip-holding parts of a carrier tape having said parts provided intermittently and longitudinally of said carrier tape, which cover tape comprises a base tape, an adhesive layer formed on only one surface of said base tape and a layer of non-adhesive radiation-cured or oxidation-cured ink pattern printed on said adhesive layer along the longitudinal direction of said base tape so that said non-adhesive layer has a width greater than that of the chips and less than that of said adhesive layer.
Claim 2
Dependent Claim
88 words
A cover tape for sealing chips in chip-holding parts of a carrier tape having said parts provided intermittently and longitudinally of said carrier tape, which cover tape comprises a base tape, an adhesive layer formed on only one surface of said base tape and a layer of non-adhesive radiation-cured or oxidation-cured ink pattern printed on said adhesive layer along the longitudinal direction of said base tape so that said non-adhesive layer has a width greater than that of the chips and less than that of said adhesive layer.
Claim 3
Dependent Claim
23 words
A cover tape as claimed in claim 1, further comprising a layer of releasing agent on the other surface of said base tape.
Claim 4
Dependent Claim
89 words
A cover tape for sealing chips in chip-holding parts of a carrier tape having said parts provided intermittently and longitudinally of said carrier tape, which cover tape comprises a base tape, an adhesive layer formed on only one surface of said base tape and a layer of non-adhesive antistatic agent containing printable material pattern printed on said adhesive layer along the longitudinal direction of said base tape so that said non-adhesive coat has a width greater than that of the chips and less than that of said adhesive layer.
Claim 5
Dependent Claim
