The invention discloses a complete machine for manufacturing a thin-film folded PCB (Printed Circuit Board), which comprises a base plate, a feeding mechanism and a stretching mechanism, wherein the feeding mechanism and the stretching mechanism are arranged on the base plate. The complete machine further comprises a backing plate, a piezoelectric micro-motion stack and a straight-line motion mechanism which are all arranged on the base plate, wherein the straight-line motion mechanism is further fixed with a fold preparation mechanism, the fold preparation mechanism includes a left rotating motor, a right rotating motor, a left rotating pressure head and a right rotating pressure head, the left rotating pressure head includes a left rotating frame, a left pressure roller member used for generating pressure marks on a shadowless elastic adhesive tape and a left adjustment assembly used for adjusting the position of the left pressure roller member, and the right rotating pressure head includes a right rotating frame, a right pressure roller member used for generating pressure marks on the shadowless elastic adhesive tape and a right adjustment assembly used for adjusting the position of the right pressure roller member. The complete machine can generate net-shaped or interference wave-shaped folds, the manufactured PCB is better in stretchability and more uniform, and the stability of the PCB is better. In addition, the complete machine has the advantages of simple structure, high efficiency and low cost, and is suitable for large-scale production.
