An electronic module preparation layer (A) and a manufacturing method therefor. The electronic module preparation layer (A) comprises a substrate (10), multiple electronic modules (20) and two release layers (30, 40). The multiple electronic modules (20) are coated in the substrate (10) by means of the two release layers (30, 40) so as to provide a protective effect. When a user needs to input a program code to various electronic modules (20), since one of the release layers, i.e. the release layer (40), is provided with an operation hole (42), a chip (21) and a fingerprint identification element (23) provided on various electronic modules (20) can communicate with the outside, and the user can directly carry out an operation of inputting the program code by means of the electronic module preparation layer (A), thereby effectively improving the defect in the prior art that various electronic modules (20) can easily be bent and damaged when directly inputting into the electronic modules (20), and an electronic module preparation layer (A) is thus provided.
