Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the carrier tape electroplating tool, and specifically relates to the structure of the electroplated carrier tape side surface conduction. BACKGROUND

[0002] The carrier tape is mainly applied to the electronic component mounting industry. It is used with the cover tape to carry and store resistors, capacitors, transistors, diodes and other electronic components in the pockets of the carrier tape, and forms a closed package by sealing the cover tape above the carrier tape to protect the electronic components from pollution and damage during transportation. When the electronic components are mounted, the cover tape is peeled off, and the automatic mounting equipment takes out the electronic components in the pockets in sequence through accurate positioning of the carrier tape index hole and mounts them on the integrated circuit board,

The upper end of the main body is provided with an insulating layer, and the upper end of the insulating layer is provided with a metal braid. The upper end of the metal braid is provided with a conductive carbon black block. The rear end of the metal braid is provided with a conductive device.
