Description

Technical Field

[0001] The utility model relates to the field of paper carrier tapes, in particular to a conductive paper carrier tape for anti-static use. Background Art

[0002] According to the material, the carrier can be divided into plastic carrier and paper carrier. Plastic carrier has high strength and good transparency, and will not generate dust and fiber pollution during use. However, due to the nature of the material itself, the dimensional accuracy of plastic carrier is difficult to guarantee, especially for plastic carriers used for miniaturized electronic components. The chamfers are difficult to eliminate during punching, and plastic has no buffering function, which can easily cause mechanical damage to electronic components. The static electricity of plastic products is also difficult to eliminate, which brings difficulties to the process of taking components. In contrast, paper carrier has the advantages of good rebound, convenient preparation and low cost. However, the carrier paper used for packaging and transportation of electronic components has very high requirements: high strength to avoid mechanical damage during use and transportation; good bonding strength to avoid paper dust from affecting the performance of electronic components or clogging the equipment for taking electronic components during punching and slitting; low conductive ion content to avoid affecting the quality of electronic components, etc.

[0003] However, paper does not have anti-static or conductive properties, and paper carriers on the market do not have anti-static or conductive properties. After static-sensitive electronic components such as semiconductor chips, capacitors, resistors, etc. are packaged with paper carriers, static electricity is easily generated due to friction during transportation or use, which can cause the electronic components to be damaged by static electricity breakdown.
