Guys and Gals, Good day. I am on the midst of my design, and i am planning to place 0603 resistor under the 1.0 mm pitch BGA and because of the 1 pin/1 via in the area, I am having difficulty placing them. Please help advice what is the minimum land pattern I can modify my standard 0603 so that I can fit them inside.. My current land pattern is rectangular 0.6 X 0.9 mm, with 1.4 pitch. Thanks |

The minimum (least environment) for a 0603 pattern is 0.70 X 0.85 with a 1.0 mm pitch. You can only put this under a 1.0 mm pitch BGA if there are unused pins in the area and you fanout your vias away from the resistor. However, you can fit a 0402 nominal resistor in-between vias. This picture is a 1.0 mm pitch BGA.
