Abstract

A number of holes for individually receiving small-sized electronic parts such as chip capacitors and ceramic capacitors are formed in a strip of carrier tape to preserve these parts. The carrier tape is made of a strip of base material and a strip of double-sided adhesive tape stuck on one surface of the base material such that the area of each portion of the adhesive layer exposed through the holes is smaller than the area of each hole. The base material is made of an electrically conductive material. Alternatively, the base material may be made of nonconductive material and the surface may be treated so as to be electrically conductive. Incisions are formed in the adhesive layer to facilitate removal of the adhesive in withdrawing the electronic parts from the tape. When the electronic parts are inserted in the holes, they are stuck on the adhesive layer, and then the tape is wound on a reel for storgage.

Claims

1. A process for packaging electronic parts comprising:

providing an elongated strip of flexible material, said strip having a surface and a length, said material having a physical characteristic of conducting electricity to an extent necessary to prevent attachment of electronic parts to the surface of said strip by static electricity,

punching a series of aligned holes in said strip, said holes being aligned in rows along the length of the elongated strip,

adhesively bonding one side of a double-sided adhesive strip to one side of the elongated strip over one row of said series of holes, a first portion of said adhesive strip being visible through each hole and a second portion of said adhesive strip not being visible through said holes, each said hole in said one row having a width perpendicular to the length of the elongated strip,

bonding a strip of release paper to the other side of the double-sided adhesive strip, said strip of release paper being of a width at least as great as the adhesive strip, said strip of release paper having two sides with (1) one side being in contact with the adhesive strip and (2) the other side not contacting the adhesive strip,

inserting an electronic part into each of at least some of the holes of said one row and into contact with said first portion and adhesively bonding said parts to the first portions of said adhesive strip which are exposed through said one row of holes,

each said first portion of said adhesive strip having a physical characteristic of releasing from said strip of release paper and from the second portion of said adhesive strip which is not exposed through said one row of holes while remaining bonded to said part in which said portion is in contact when force is applied to remove said part from said hole, and

while leaving the holes in said one row unobstructed from one side of the elongated strip rolling the elongated strip, electronic parts, adhesive strip and release paper into a coil in a direction, the direction of rolling being along the aligned row of holes whereby the other side of the release paper covers said unobstructed holes.

2. The process of claim 1 including forming incisions in said adhesive strip whereby when force is applied to remove an electronic part from its hole, a discrete portion of the adhesive strip defined by the incisions remains bonded to said electronic part being removed.

3. The process of claim 2 wherein another row of said series of holes formed in the elongated strip is formed adjacent to and out of contract with one edge of the elongated strip, whereby said another row of holes may serve as a means for moving the elongated strip by a sprocket wheel.

4. The process of claim 3 wherein the elongated strip includes a mixture of paper fibers and carbon black.

5. The process of claim 2 wherein the incisions are made in the adhesive strip prior to the time said adhesive strip is bonded to the elongated strip.

6. The process of claim 2 wherein the incisions are made in the adhesive strip subsequent to the time said adhesive strip is bonded to the elongated strip.

7. A process for packaging electronic parts, storing said electronic parts and subsequently using at least one of said parts, said process comprising;

providing an elongated strip of flexible material, said strip having a surface and a length, said material having a physical characteristic of conducting electricity to an extent necessary to prevent attachment of electronic parts to the surface of said strip by static electricity,

punching a series of aligned holes in said strip, said holes being aligned in rows along the length of the elongated strip,

adhesively bonding one side of a double-sided adhesive strip to one side of the elongated strip over one row of said series of holes, a first portion of said adhesive strip being visible through each hole and a second portion of said adhesive strip not being visible through said holes, each said hole in said one row having a width perpendicular to the length of the elongated strip, the width of said adhesive strip being less than the width of each said hole,

bonding a strip of release paper to the other side of the double-sided adhesive strip, said strip of release paper being of a width at least as great as the adhesive strip, said strip of release paper having two sides with (1) one side being in contact with the adhesive strip and (2) the other side not contacting the adhesive strip,

inserting an electronic part into each of at least some of the hole of said one row and into contact with said first portion and adhesively bonding said parts to the first portions of said adhesive strip which are exposed through said one row of holes,

each said first portion of said adhesive strip having a physical characteristic of releasing from said strip of release paper and from the second portion of said adhesive strip which is not exposed through said one row of holes while remaining bonded to said part in which said portion is in contact when force is applied to remove said part from said hole,

while leaving the holes in said one row unobstructed from one side of the elongated strip rolling the elongated strip, electronic parts, adhesive strip and release paper into a coil in a direction the direction of rolling being along the aligned row of holes whereby the other side of the release paper covers said unobstructed holes; and

removing at least one electronic part from the hole where it was previously inserted by application of a vacuum and the part so removed is then bonded to a component of electronic equipment solely by the adhesive on the part which separated from the release strip with the part when said part was removed from the hole.

8. The process of claim 7 including forming incisions in said adhesive strip whereby when force is applied to remove an electronic part from its hole, a discrete portion of the adhesive strip defined by the incisions remains bonded to said electronic part being removed.

9. The process of claim 8 wherein another row of said series of holes formed in the elongated strip is formed adjacent to and out of contact with one edge of the elongated strip, whereby said another row of holes may serve as a means for moving the elongated strip by a sprocket wheel.

10. The process of claim 9 wherein the elongated strip includes a mixture of paper fibers and carbon black.

11. The process of claim 8 wherein the incisions are made in the adhesive strip prior to the time said adhesive strip is bonded to the elongated strip.

12. The process of claim 8 wherein the incisions are made in the adhesive strip subsequent to the time said adhesive strip is bonded to the elongated strip.
