12 Layer PCB - MOKO Technology
To design the outer layer, foils of copper with various weight (0.5 ounces or more) are used. Most times the 12 Layer PCB board is produced efficiently on a 1.6mm thick board. There are more 14 to 16 layer boards fabricated into 1.6mm thick boards, while the number of 12 layer PCB produced is limited to the manufacturers which produce HDI boards.
