The invention relates to a circuit board packaged on a dressing. The circuit board packaged on a dressing comprises a circuit board packaged on a dressing body, the circuit board packaged on the dressing body comprises a plurality of circuit board modules arranged in matrix, and a flexible conduit used for traversing a connecting thread is arranged between two adjacent circuit board modules to make the circuit board modules and the conduit be interlaced and assigned to form a netted structure; any two circuit board modules can be connected through a connecting line inserted in a conduit; and the circuit board modules are coated with shells, and the shells and the conduits are connected into one body. The circuit board packaged on a dressing allows a traditional circuit board to be packaged in the dressing like a dressing cloth material, so people feels comfortable; and the circuit board packaged on a dressing has the advantages of low cost, low technical difficulty, easy realization, convenient dismounting, and convenience for dressing cleaning.
