# Carrier Tape Specifications for Electronic Component Packaging
## Introduction to Carrier Tape
Carrier tape is an essential component in the electronic manufacturing industry, designed to protect and transport delicate electronic components during the assembly process. This specialized packaging solution ensures components remain securely positioned and undamaged from the manufacturer to the pick-and-place machines on the production line.
## Key Specifications of Carrier Tape
### 1. Material Composition
Most carrier tapes are made from:
– Polystyrene (PS)
– Polycarbonate (PC)
– Anti-static materials
– Conductive materials for sensitive components
The material choice depends on the component’s sensitivity and the required level of protection.
### 2. Dimensional Standards
Carrier tapes must adhere to strict dimensional specifications:
– Width: Typically ranges from 8mm to 56mm
– Pocket spacing: Standardized for automated equipment
– Pocket depth: Varies based on component height
– Thickness: Usually between 0.2mm to 0.5mm
### 3. Pocket Design
The pocket configuration is critical for component security:
– Rectangular pockets for standard components
– Circular pockets for certain ICs
– Custom shapes for specialized components
– Anti-static coatings for sensitive devices
