本实施例中，如图2、图3、图4所示，所述线材本体100的两端部均具有第一金手指110和第二金手指120。所述第一排线层131的两端均形成有第一金手指110。所述第一正排线1311、第二正排线1312、……、第n-1正排线1313以及第n正排线1314的两端上均设有预打孔，且第一正排线1311、第二正排线1312、……、第n-1正排线1313以及第n正排线1314上每端的预打孔依次排列形成朝向内侧倾斜的第一倾斜直线。所述第二线材140对应为两片。其中一片所述第二线材140贴设在所述第一线材130的反面的第一端，该第二线材140的第二排线层141形成的第二金手指120与所述第一线材130的第一端的第一金手指110相对应。其中另一片所述第二线材140贴设在所述第一线材130的反面的第二端，该第二线材140的第二排线层141形成的第二金手指120与所述第一线材130的第二端的第一金手指110相对应。进而，本实施例的FFC线结构的两端均可实现双面接触且传输信号一致效果。
本实施例中，所述第一正排线1311上的预打孔与所述正PIN1引脚1311a之间的距离≥5mm。进而，将第二线材140的预打孔与第一线材130的预打孔进行金属过孔压合时，不会对金手指处的各引脚造成损坏。本实施例中，所述线材本体100的端部设有防脱落凹槽150，本实施例的FFC线结构与PCBA等进行插接接触时，可与PCBA接口的结构配合实现防脱落效果。
如图2、图3、图4、图6所示，一种制造所述的FFC线结构的制造方法，包括以下步骤：
准备第一线材130：第一线材包括第一正排线1311、第二正排线1312、……、第n-1正排线1313以及第n正排线1314，所述第一正排线1311、第二正排线1312、……、第n-1正排线1313以及第n正排线1314的端部对应形成正PIN1引脚1311a、正PIN2引脚1312a、……、正PINn-1引脚1313a、正PINn引脚1314a，在第一正排线1311、第二正排线1312、……、第n-1正排线1313以及第n正排线1314上分别开设第一预打孔1315；
准备第二线材140：第二线材140包括第一反排线1411、第二反排线1412、……、第n-1反排线1413以及第n反排线1414，所述第一反排线1411、 第二反排线1412、……、第n-1反排线1413以及第n反排线1414的端部对应形成反PIN1引脚1411a、反PIN2引脚1412a、……、反PINn-1引脚1413a、反PINn引脚1414a，在第一反排线1411、第二反排线1412、……、第n-1反排线1413以及第n反排线1414上分别开设第二预打孔；
形成线材本体100：将第二线材140金属过孔压合在第一线材130的背面，第一正排线1311、第二正排线1312、……、第n-1正排线1313、第n正排线1314上的第一预打孔1315与第一反排线1411、第二反排线1412、……、第n-1反排线1413、第n反排线1414上的第二预打孔1415一一对应导通，正PIN1引脚1311a、正PIN2引脚1312a、……、正PINn-1引脚1313a、正PINn引脚1314a与反PINn引脚1414a、反PINn-1引脚1413a、……、反PIN2引脚1412a、反PIN1引脚1411a一一对应相对设置；其中，n为正整数，且n≥2。
所述FFC线结构的制造方法，第一正排线1311、第二正排线1312、……、第n-1正排线1313、第n正排线1314上的第一预打孔1315与第一反排线1411、第二反排线1412、……、第n-1反排线1413、第n反排线1414上的第二预打孔1415一一对应导通，正PIN1引脚1311a、正PIN2引脚1312a、……、正PINn-1引脚1313a、正PINn引脚1314a与反PINn引脚1414a、反PINn-1引脚1413a、……、反PIN2引脚1412a、反PIN1引脚1411a一一对应相对设置，可实现第一金手指110与第二金手指120的接触传输信号一致，制造得到的FFC线结构，使用时其端部可实现双面接触且达到传输信号一致的效果，相比于传统FFC线端部一面为金手指一面为补强板面的结构，采用该制造方法制造得到的FFC线结构使用时不需要考虑与PCBA等的接触是否为补强板面或是金手指面，尤其适用于复杂走线设计，不易出现设计错误。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
