Disclosed are a chip card assembling structure and a method thereof, including at least one base plate, at least one fixing element having a side forming a fixing trough corresponding to the base plate, at least one adhesive film disposed on one side of the fixing element to cover the fixing trough, and at least one thin-film chip received in the fixing trough and bonded to the adhesive film. To use the present invention, the adhesive film, together with the thin-film chip, is lifted and the base plate is placed into the fixing trough, following setting the adhesive film and the thin-film chip back to have the thin-film chip coupled to the base plate. Then, the adhesive film is lifted to remove the coupled thin-film chip and base plate, so that the relative position between the thin-film chip and the base plate is precise and correct.
