BGA区域走线时，能否两个gnd pin 共用一个gnd via?
我需要和产品线工程师确认一下。
工程师建议每个GND用自己的GND via。请看下面的回复。Recommendation is for each GND ball to have its own GND via - as shown in TI's example designs (EVM, Starter Kit, etc). The minimizes the inductance of the GND return path for both power and high speed signal.https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1292429/tda4vm-can-two-gnd-pins-use-the-same-gnd-via
