Problems solved by technology

[0006] However, when the surface is coated with a liquid composed of a water-soluble polymer, the adhesiveness decreases when the covering tape is adhered by adhesive sealing, and unexpected failures such as peeling of the covering tape may occur during the process of taking out the electronic component.
Of course, if the water-soluble polymer liquid is not applied, although the adhesiveness of the coated tape is good, because the surface strength of the carrier tape material is reduced, fluff or dust (slurry fiber powder, etc.) may be generated when the coated tape is peeled off, or Damage to the paper layer, such as paper peeling, occurs

Embodiment 1

[0074] Cut the carrier tape material made as above into a width of 8mm, at a temperature of 160°C and a pressure of 0.5kg / cm 2 Only the 2 mm wide part of the polyethylene terephthalate coated tape was heat-sealed for 1 second under the conditions, and after standing for 15 minutes, it was peeled at 180 degrees using a universal tensile testing machine, and the peeling force (N) was measured.

[0075] (parts removal test)

[0076] Put the carrier tape material prepared as above together with the bottom cover paper on the chip-type electronic component loading device to form a mold cavity for electronic component filling, attach the bottom cover paper, load the electronic components, and attach the top cover tape to make the carrier tape (final product). Then, peeling of the covering tape and taking out of the electronic component were performed using the electronic component take-out device. At this time, observe whether there is any failure. The case where there is no failu...

Embodiment 2

[0084] Except that the components of the mixed solution were 50 parts of PVA and 50 parts of styrene-acrylic resin, a carrier tape material was produced in the same manner as in Example 1, and each test was performed.

Embodiment 3

[0086] A carrier tape was produced in the same manner as in Example 2 except that the melting point of the styrene-acrylic resin was changed to 90° C., and various tests were performed.

Abstract

The invention relates to a kind of material of bearing belt and bearing belt. The bearing material mentioned is the material that can not only warm and splice the bearing belt, avoiding the trouble that can't be anticipated, but avoiding destroying the wall paper when stripping the bearing belt. As far as the bearing belt made of raw material of fiber contains thick liquid is concerned, at least one side of which is covered with the liquid comprised of macromolecule solution of which the active principle is 90:10 to 50:50, and styrene-acrylic acid resin, the fusion point of which is 80 to 120centigrade.

Description

[technical field] [0001] The present invention relates to a carrier tape and a carrier tape material used for loading electronic components, and more specifically, to a carrier tape material and a carrier tape whose cover tape has high heat-sealing adhesiveness and whose surface is hardly damaged when peeled off. [Background technique] [0002] In recent years, various electronic devices have been manufactured using various technologies for automatically assembling various electronic components on circuit boards. Among them, the technology of directly mounting various surface mount components on the surface of the circuit board, the so-called surface mount technology, has made significant progress. [0003] In such a surface mount, a carrier tape formed of a carrier tape material is generally used. The carrier tape material is processed, for example, to form a cavity portion for storing surface mount components, to obtain a carrier tape. This not only accommodates the surf...
