发明名称 A METHOD AND A DEVICE FOR SHIELDING OF ELECTRONIC COMPONENTS ON A CIRCUIT BOARD
摘要 The invention relates to a device and a method for shielding of electronic components on a circuit board (1). A shielding unit (3), comprising an inner side surface (7) and an outer side surface (6), is fixed on the circuit board (1), e.g. by soldering, and the shielding unit (3) encloses a number of electronic components. The electronic components, which are situated closest to the inner side surface (7) and the outer side surface (6) of the shielding unit, comprise a pole (P1, P2, P3, P4) which is coupled to a common earth connection on the circuit board (1). These electronic components are arranged on the circuit board (1) so that their poles (P1, P2, P3, P4) are facing respectively towards the inner side surface (7) and the outer side surface (6) of the shielding unit. These electronic components are also arranged on the circuit board (1) so that the side of these electronic components which is facing respectively towards said inner side surface (7) and said outer side surface (6) are placed at least a certain distance (d) from the other electronic components (K1, K2, K3, K4) on the circuit board (1). Several modified examples are described in the application.
