Help!!! Have anyone out there designing PCB using the IPC-D-275 process control test coupons? I am having a hard time trying to understand the spec. Any samples, guideline or clarification will be helpful. Our typical PWBs are 8 to 24 layers with 2 to 8 layers being plane layer, mixed technology with very fine pitch devices, no blind and buried via.
