Example Embodiment
[0027] Preferably, after the step B, visual inspection and tensile force inspection are also included. The visual inspection here is to check whether the FPC is scratched during the operation. The main result of the connection of the flexible printed circuit board is to refer to the continuity and reliability. Whether the resistance is good or not, the tensile strength inspection standard is generally given according to customer needs. As an embodiment, the magnitude of the pulling force required by the FPC connecting structure may be greater than 200 g / cm.
[0028] In the manufacturing method of the flexible printed circuit board connecting structure, the electrical connection between the module FPC and the connecting FPC adopts ACF connection, which has good high temperature stability, low thermal expansion coefficient, low moisture absorption, and excellent conductivity; it can be based on the FPC gold finger Conductive gold balls with different diameters are selected for t...
