Embodiment Construction
[0022] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] The present invention changes the layout of the traditional interface unit so that the main power line / ground area in the interface unit is separated from the package pad area, thereby reducing the conflict between the package pad and the power line / ground line in the interface unit, thereby reducing the overall The number of metal layers reduces costs.
[0024] Please refer to image 3 As shown, it is a schematic diagram of the layout layout of the signal unit that does not show the package pad in one embodiment of the present invention; please refer to Figure 4 shown in the image 3 A schematic diagram of the layout layout of the signal unit after adding the package pad in . Depend on image 3 and Figure 4 It can b...
