I'm checking an artwork and the minimum trace to trace spacing on the layer of interest is 10mil.
The pad to pad minimum spacing is 6mil due to the presence of a particular footprint.
The test coupon E has the spacing of 10mil in the layer of interest.
Is this correct as per IPC-D-275 or it should be 6mil???
The artwork designer says only the trace to trace spacing should be considered.
Can anyone:- explain which spacing is the right one and why
Thanks,
