Part area B (white portion), and inductance 104 is arranged under the second part area B.A plurality of welderings designed by the present embodiment
The not substantive overlying lid whole chip 400 of ball array 401, and the vertically oriented portion of inductance 104 is avoided, the design can significantly subtract
Few electromagnetic interference between inductance 104 and arrays of solder balls 401, increase inductance 104 use upper quality.In addition, the area of inductance 104
Design it is also unsuitable excessive, avoid the density of arrays of solder balls 401 too high, i.e., first part area A is too small, and causes arrays of solder balls
Interference problem on 401 between signal.Therefore in one embodiment, first part area used in arrays of solder balls 401 be by
Design is at least above the chip 50%.Note, in arrays of solder balls 401, the interval D between soldered ball and soldered ball also belongs to first
Part area A, rather than the second part area B.
Fig. 6 is an embodiment schematic diagram of inductor design.In order to obtain higher quality inductance, one embodiment of the invention
Using 8 font inductance 600.8 font inductance present two circulations, i.e. first circulation 602 and second circulation 604, and first
Circulation 602 differs with the sense of current in second circulation 604.When the sense of current of first circulation 602 is wink clockwise,
It is then counterclockwise that the sense of current of second circulation 604, which is,.The advantages of 8 font inductance, is structural symmetry height, can reduce
Interference, is more suitable for the design of high-frequency circuit.
