Abstract: Activatable thermal fuse (10) comprising - a first (1) and a second (2) electrical terminal, - an electrically conductive bridge element (3) being in a first electric contact with said first terminal and being in a second electric contact with said second terminal, - at least a part (4) of said bridge element being displaceable from a first position in which said first contact is established to a second position in which said first contact is opened, - a thermally sensitive member (5) holding said part in said first position and releasing said part as soon as said thermally sensitive member is exposed to a predetermined temperature value, - a biasing member (6) biasing said part towards said second position, and - a mechanically displaceable activating element (7) blocking displaceability of said part in said first position in a first position of said activating element and enabling said displaceability of said part in a second position of said activating element. The invention is further directed to a method of manufacturing a printed circuit board with an activatable thermal fuse, a method of monitoring an activatable thermal fuse and to an electronical circuit comprising an activatable thermal fuse.Activatable thermal fuse (10) comprising - a first (1) and a second (2) electrical terminal, - an electrically conductive bridge element (3) being in a first electric contact with said first terminal and being in a second electric contact with said second terminal, - at least a part (4) of said bridge element being displaceable from a first position in which said first contact is established to a second position in which said first contact is opened, - a thermally sensitive member (5) holding said part in said first position and releasing said part as soon as said thermally sensitive member is exposed to a predetermined temperature value, - a biasing member (6) biasing said part towards said second position, and - a mechanically displaceable activating element (7) blocking displaceability of said part in said first position in a first position of said activating element and enabling said displaceability of said part in a second position of said activating element. The invention is further directed to a method of manufacturing a printed circuit board with an activatable thermal fuse, a method of monitoring an activatable thermal fuse and to an electronical circuit comprising an activatable thermal fuse. The present invention provides a phased antenna array device (100) and its fabrication method (400). The device 100 comprises a first dielectric layer (D1), and at least one die (101) embedded into the first dielectric layer (D1). The die (101) is configured to output phase-shifted signals for driving antenna elements. The device (100) also comprises a second dielectric layer (D2), which is provided on the first dielectric layer (D1). Further, an interconnection structure (102) is formed in a first metal layer (M1), which is provided between the first dielectric layer (D1) and the second dielectric layer (D2). Additionally, a plurality of first antenna elements (103) formed in a second metal layer (M2) is provided on the surface of the second dielectric layer (D2). These first antenna elements (103) are connected via the interconnection structure (102) to the at least one die (101).
