[0002] The soldering tape is also called tinned copper tape or tin-coated copper tape. It is divided into busbars and interconnecting strips. It is used to connect the solar cells of photovoltaic modules and plays an important role in conducting electricity. However, the soldering tape may have quality problems such as bending and tin leakage during the production process, so a soldering tape inspection device is needed.
