Standard Multi-Layer PCB Stackups
This article defines the materials and the standard stackups our suppliers use for 2-layer to 10-layer PCB’s. You can provide your own custom stackup but these are the most commonly used. When designing your PCB's if you design with these stackups in mind it should help cut lead-times and improve yields.
Core PCB/Prepreg Materials Commonly Use
