Abstract
A carrier tape for electronic or electrical devices which contains a pocketless support film, a fastening layer on the support film, and a deformable cover film separably attached to the fastening layer. The devices are sandwiched between the fastening layer and the cover film, which deforms to provide an enclosure for the devices.

A method of processing electronic or electrical devices which comprises
- (A) providing an assembly of electronic or electrical devices which comprises
- (1) a flexible support film which (a) is composed of a polymeric material, and (b) comprises (i) two longitudinally extending edge portions, and (ii) a substantially flat, longitudinally extending central portion between the edge portions;
- (2) supported by the support film, a fastening layer which is composed of a polymeric material;
- (3) a deformable cover film which (a) is composed of a polymeric material, and (b) is separably attached to the fastening layer;
- and
- (4) a plurality of electronic or electrical devices which are positioned at spaced-apart locations between the cover film and the central portion of the support film, the cover film being deformed around the devices;
- (B) advancing said assembly through a work station which separates the cover film from the fastening layer, thus sequentially exposing the devices;
- and
- (C) sequentially removing the exposed devices from the support film.
6 more elements
A support member for use in tape carriers for electronic and electrical devices, the member comprising
- (1) a flexible support film which (a) is composed of a polymeric material, (b) is 0.25 to 2.00 inch wide and (c) comprises (i) two longitudinally extending edge portions, at least one of the edge portions having sprocket holes at longitudinally spaced regular intervals, and (ii) a substantially flat longitudinally extending central portion between the edge portions;
- and
- (2) supported on the central portion of the support film, a fastening layer.
