According to the consulting data query, from January to December 2014, the output of electronic components in China was 3820.8 billion and the output of semiconductor discrete devices was 535.942 billion (semiconductor discrete devices are an important electronic product in electronic devices, which is selected as the data basis for calculating the market share of the issuer, which has a certain reference value).

The thin carrier tape of electronic components can be roughly divided into paper carrier tape and plastic carrier tape. The paper carrier tape is mostly used for the packaging of electronic components with a thickness of no more than 1mm. When the thickness of electronic components exceeds 1mm, plastic carrier tape is often used for packaging due to the limitation of bending conditions. Compared with semiconductor discrete devices, electronic components are usually smaller and thinner, so paper carrier tapes are mostly used to package electronic components, while plastic carrier tapes are used to package semiconductor discrete devices.

In surface mounting, electronic components correspond to a hole on the carrier belt, and there is a certain quantitative relationship between them. At present, the spacing between the two holes on the paper carrier belt is mostly 2mm and 4mm. If the middle value is 3mm, based on the output of 3820.8 billion electronic components in China in 2014, the corresponding use of paper carrier belt is about 11.462 billion meters; The spacing between the two holes on the plastic carrier belt is mostly 4mm, 6mm and 8mm. If the spacing is 5mm, only based on the output of 535.942 billion semiconductor discrete devices in China in 2014, the use of plastic carrier belt corresponding to semiconductor discrete devices is about 2.680 billion meters.
