Flexible printed circuits of easily stereotyping

The utility model belongs to the technical field of the technique of circuit board and specifically relates to a flexible printed circuits of easily stereotyping, it distorts the cylindrical flexible substrate of cylinder forming to include under the exogenic action, the inside of flexible substrate hug closely the cover and be equipped with cylindric elasticity die sleeve, a plurality of finding activate road troughs have evenly been offered to the outside of flexible substrate, every finding activate road trough in all fill out and be equipped with the circuit, the kneck of flexible substrate evenly is provided with a plurality ofly to connecting the hasp. The flexible printed circuits is stereotyped effectually, is difficult to the phenomenon that has a rebound and reply, and the in -service use in -process just also is difficult to appear the incident problem.
