Abstract:
Provided is a differential wiring method for a high-speed printed circuit board, including the following steps: setting a pre-set impedance required value Z 2  of a non-ball grid array (BGA) region, determining the width w 2  of the second differential wire ( 210 ) and the distance d 2  between the two second differential wires ( 210 ) according to the pre-set impedance required value Z 2 ; calculating the width w 1  of the first differential wire ( 110 ) and the distance d 1  between the two first differential wires ( 110 ), according to the distance s 1  between two adjacent rows of bonding pads in a BGA region bonding pad array and the minimum processable distance s 2  between the bonding pad and the first differential wire ( 110 ), where w 1  and d 1  should satisfy 2w 1 +d 1 ≤s 1 −2s 2 , while further calculating w 1  and d 1  according to a differential characteristic impedance formula; arranging the two first differential wires ( 110 ) disposed oppositely to each other in the BGA region according to the determined d 1 , and arranging the two second differential wires ( 210 ) disposed oppositely to each other in the non-BGA region according to the determined d 2 ; connecting the first differential wire ( 110 ) and the second differential wire ( 210 ) corresponding thereto via a first connection wire ( 310 ); and connecting the first differential wire ( 110 ) and the bonding pad ( 120 ) corresponding thereto via a second connection wire ( 320 ).

Claim (Index 1):
