A package comprises a substrate (101 , 401 ) with a longitudinal direction and a lateral direction perpendicular thereto. The substrate (101 , 401 ) has a recess (103, 403) formed in a first surface (102, 402) and the recess (103, 403) extends in the longitudi¬ nal direction of the substrate (101 , 401), said recess (103, 403) having an inner sur¬ face. The inner surface of the recess (103, 403) comprises at least a first set of con¬ ductive areas. The first set comprises at least a first area (106, 406) and a second area (107, 407) being provided with a conductive layer, said first area (106, 406) and said second area (107, 407) being mutually spaced in the lateral direction. The package ad¬ ditionally comprises a cap (151 , 251 , 351 , 451.) with a first surface (152, 252, 352, 452) for mounting on top of said first surface (102, 402) of said substrate (101, 401), the cap (151 , 251 , 351 , 451 ) and the recess (103, 403) of the substrate (101 , 401 ) defining an elongated channel in the longitudinal direction. The cap (151 , 251 , 351 ) comprises at least a first set of conductive areas, said first set comprising at least a first area (156, 256, 356) and a second area (157, 257, 357) provided with a conductive layer, said first area (156, 256, 356) and said second area (157, 257, 357) being mutually spaced in the lateral direction. |
