My bet is that you get to assembly and testing -- it's unacceptable for them
to touch.

Ok then, can anyone enlighten me slowly? Lemme rephrase it a bit....

1206 resistor pads are 1.8 wide. The body is 1.8 max wide. IPC-A-610B,
class 2 says it's acceptable as long as you have 50% overlap of widths...
so it can move .9 either side... so that's a box 3.6 wide that is ok...
right so far? So if two 1206 resistors are side by side, 3.6 apart, and
each part is shifted worst case, they touch. Is that an acceptable
condition per IPC-A-610B, class 2? Or does it mean the parts have to be
spaced further than 3.6 in order to insure that your board is
manufacturable per IPC-A-610B, class 2? Or does anything mean anything
anymore? C'mon y'all....Jo-Ann?... Gary?... Abdulrahman?...

Thank you in advance for all your help ;-)
