Embodiments herein relate to a Printed Circuit Board, PCB, (1) and a terminal (2) for connecting the PCB (1) to an electrical component. The PCB (1) comprises a through-hole (11) for receiving the terminal (2). The through-hole (11) has a partially open side wall (12), wherein the side wall (12) is open along at least a part of a length (L) of the 5 through-hole (11) perpendicular to a radius (R) of the through-hole (11). This allows the terminal (2) to protrude through the open side wall (12) when received by the through-hole (11), such that a position of the terminal (2) is adjustable along the length of the open side wall (12). The terminal (2) comprises a base (21), adapted to be received by the through-hole (11) of the PCB (1) and to create a press fit with the side wall (12) of the through-hole 10 (11), and a pin (22) projecting from a surface (23) of the base (21).
