Arm assembly for a disk drive device and a method for fabricating the same

An arm assembly for a disk drive device comprising:

• a plurality of arms arranged in parallel to each other with a space, one end of each of said arms being fixed to each other;
• the other end of each of said arms supporting a read/write head, and each of said arms having an extended plate which cantilevers from one of the side edges of said arm;
• a plurality of first electrically conducting connecting pads provided on each of said extended plates, said first connecting pads being connected to said read/write head;
• and
• a circuit board comprising a non-electrically conductive support member, an insulating layer, and second electrically conducting connecting pads, the insulating layer and second conducting pads extending beyond the edge of the support member, the circuit board provided with a plurality of open ended slots for receiving said extended plates, the plurality of second connecting pads being provided on a surface portion of each of the edges of said open ended slots, characterized in that said circuit board is approximately orthogonal to the plane of said extended plates of said plurality of arms to align said second connecting pads on said edges of said open ended slots with said first connecting pads on each of said extended plates.
