PURPOSE: A structure for forming a portable phone PCB(Printed Circuit Board) pattern is provided to prevent a pattern formed at the back of a PCB from being short-circuited, due to a user's long-term and repetitive use. CONSTITUTION: The longitudinal width(Y) of a pattern(11) formed at the back of a PCB is 800μm. A connection part(13) connected to a pad(12) is formed in the shape of a lozenge so that shock-absorbing can be made in a direction that force is pressed. The horizontal width(X) of the connection part(13) is 200μm. The longitudinal width(Y) of the pad(12) is 1350μm.
