Firstly, high precision is required for the carrier tape
Secondly, the speed of taking and placing components and discrete components by SMT machine is faster and faster, and one cycle has been less than 0.09 seconds, which puts forward the requirement of high tensile strength for the carrier tape material;
Third, the cost is reduced, and high-density packaging is required (packaging spacing is 2mm, usually 4mm);
Finally, anti-static protection. Because the components are very small and easy to be adsorbed by static electricity, the SMT machine cannot get the components or the components turn sideways.
