The cover tape in the tape carrying system has two ways: thermal and pressure-sensitive. The thermal cover tape has no viscosity at room temperature and has viscosity only after heating; Both sides of the pressure-sensitive cover tape have viscosity at room temperature. Just like the electrical insulating tape, it does not need to be heated. Compared with the thermal cover tape, the pressure-sensitive cover tape has four advantages:

1. No heating, easy to use;

2. The adhesion is very stable and not easy to degumm;

3. There is no obvious difference between the effect of re bonding and the effect of initial bonding, so it is very convenient to replace components;

4. The anti-static effect is better and can reach the electrostatic conductivity level.

In short, the tape carrying system has been innovating to provide better protection for the ever-changing SMD components and make them more convenient to be used by SMT machines. As a carrier tape supplier, 3M has all series of products of PC, PS tape and pressure-sensitive and thermal cover tape.

3M also makes use of the advantages of PC and film and glue technology to continuously develop 2mm spacing belt carrying system and electrostatic dissipation tapet carrying system, which are used for flipchip, cob (bare die) high-purity and high-precision belt carrying system, the system that can enter the oven together with components, and the tape carrying system of BGA can be directly monitored in the belt.
