How to connect to inner BGA pins ?

1263 2

Pazh 4 years ago

Hi Everyone, I'm using the LM48580TLX/NOPB chip in my design. It's a BGA component and I do not understand how I can connect to the inner pins. The PCB layout I found at easyeda does not have vias. When I looked at other BGA's I've noticed that it's all look the same. What am I missing ? Can anybody help ? Thank, Ph

See also: [https://jlcpcb.com/capabilities/Capabilities](https://jlcpcb.com/capabilities/Capabilities) and note that EasyEDA and JLCPCB do not currently support blind and micro vias.
