The waterproof property is unstable.
2. The solder joint protection of connector mainly relies on the sticky tape to protect, because consider the requirement in encapsulation space, the sticky tape area of pasting is less, and thickness is generally not more than 0.5mm, so at the plastic packaging in-process of moulding plastics, the sticky tape of pasting is destroyed by the encapsulating material impact force easily, can lead to waterproof performance inefficacy.
3. Due to the fact that the number of the communicated circuits of the connector is different, due to the fact that the shrinkage of the packaging material of the connector with the plurality of passages can cause the plurality of paths of flat cables to be unparallel, the distance between the tail ends of the cables is changed, and the size of the connector is not qualified.
4. As the flat cable is 0.17mm in the thinnest total thickness at present, the flat cable at the packaging position is easily impacted by packaging materials in the injection molding process, so that the flat cable is curled or deviated at the injection molding position, the flat cable possibly leaks to the outer side of the packaging body in a naked mode, and the waterproof performance fails.
