What impact does the material of the carrier tape have on the application scenario?

1、 Differences in Performance and Scene Effects of Four Mainstream Materials
1. Paper carrier tape (kraft paper composite)
Key material characteristics
The depth of the cavity is ≤ 1mm, it is not resistant to moisture, high temperature, cannot be used as a deep groove, environmentally friendly and easily degradable, electrostatically stable, the lowest price, and can only be used for 8mm narrow strips.
Limitations on the Scene
Applicable: Thin chip resistors and capacitors (0201/0402), small diodes, large quantities of low-cost small household appliances, chargers, and universal components for remote controls;
Cannot be used in damp workshops, large components, deep cavity components, vehicle mounted/high-temperature processes.
2. PS polystyrene carrier tape (the most commonly used plastic carrier tape on the market)
Key material characteristics
Easy to form, moderate cost, temperature resistance of ≈ 85 ℃, brittle at low temperatures, large thermal shrinkage, excellent shallow cavity forming.
Impact on the scene
Applicable: SOT-23, SMD LED, small inductor, small SOP, ordinary consumer electronics (headphones, power banks, smart bracelets) room temperature SMT patch;
Prohibited: Reflow soldering preheating in high-temperature environments, automotive high-temperature components, deep cavity large parts (shielding covers, connectors).
3. APET/PET carrier tape (preferred for precision components)
Key material characteristics
Small size shrinkage, high stability, permanent anti-static, temperature resistance of around 105 ℃, high transparency, high cavity accuracy, thin precision groove.
Impact on the scene
Applicable: Crystal oscillators, sensors, camera chips, QFN, FPC small parts, smart wearables, medical electronics, precision components for mobile phones;
Advantages: Small dimensional tolerance of components, no jamming of high-speed braiding machines, preferred for precision ICs;
Shortcoming: The cost of thick and deep cavities is relatively high, and oversized hardware is not cost-effective.
4. PC polycarbonate carrier tape (deep cavity, high temperature resistant)
Key material characteristics
Temperature resistance of 125 ℃, extremely strong toughness, capable of producing 5-15mm deep cavities, bending resistance, high strength, and relatively high price.
Impact on the scene
Applicable: connectors, shielding covers, power inductors, vehicle terminals, relays, large volume hardware spring plates, automotive electronics, new energy industrial control components;
It is the only preferred material for large shaped components;
No need for: micro 0402 resistor capacitor (cost waste).
5. PI Polyimide (Special High Temperature Carrier Tape)
Temperature resistance of 200 ℃+, ultra-high price
It is only used in military, automotive power chips, and high-temperature devices, and is almost not used in civilian electronic products.
