Features of cover tape for embossed carrier tapes

DNP's cover tape is used to seal embossed carrier tapes (materials for transporting electronic components and semiconductor parts). With its stable sealing strength, it prevents the tape from peeling off during assembly and ensures that the products do not pop out. As a result, it is widely used for various products, including connectors, quartz crystal units, LEDs, switches, capacitors, coils, resistors, and semiconductors (analog ICs, logic IC, memory).

You can clearly see the contents through the cover tape,because our products are highly transparent and have excellent visibility.
This helps prevents false detections by inspection equipment and maintains productivity during mass production.

A comparison photo shows that the improved cover tape outperforms our standard one in terms of transparency.





Product lineup of cover tapes for embossed carrier tapes

DNP has a product lineup of cover tapes that can be used in a wide range of sealing temperature conditions and with various carrier tape materials (PC, PS, A-PET, PP).
 ※The table below shows a selection from our product lineup.

This is the product lineup of DNP's cover tape and the physical property data measured within DNP. This shows the surface resistivity, total light transmission rate, Cloudiness(haze value), tensile fracture stress,thickness, adapted carrier tape material and applicable products.




Features of cover tape for paper carrier tapes

Cover tape for paper carriers is called top tape. Top tape is used to seal paper carrier tape that transports electronic components and semiconductor products.
It is used for a wide range of products, including multilayer ceramic capacitors(MLCC), piezoelectric elements, inductors (coils), and varistors.

DNP's top tape experiences minimal changes in surface resistivity and peel charge voltage even after being exposed to environmental stress (high temperature and humidity).
This reduces the risk of products sticking to the cover tape or popping out during the assembly process.

This is an illustration showing the features of DNP's top tape.DNP’s top tape is characterized by its low risk of products sticking to it.





You can be confident about exporting them to hot and humid regions or transporting them by sea for long periods of time, because our products are not affected by high temperatures or high humidity.

This is a table showing the features of DNP's top tape.DNP's top tape shows almost no change in surface resistivity and peeling electric charge before and after environmental testing.
