Increasingly complex PCBs developed in EM noisy environment
PCB sizes vary from 5 to 20 square inches and a typical board for a printer will have eight layers and 500 components. Depending on the mix of passives and ICs, the number of pins/pads will vary from 1,800 to 2,200, with the number of nets varying from 900 to 1,700. Valetti continues: “One of the most complex designs we did recently had 902 components, three of which were high-pin-count BGAs. In total, there were about 3,000 pins/pads and about 2,000 nets for that design.”
