How will you decide the layer stack up. The first consideration for your PCB stackup is determining how many layers are needed. This includes considering signal (high speed, low speed), power (for high power boards or when power supplies are a part of your circuit) and ground layers or planes. It is highly recommended…

Layer stack-up means the arrangement of the copper layers and the insulating layers before PCB layout design, and these layers form a PCB. The consideration of layer stack-up depends on the technical capabilities of the production and the electrical performance requirements of the PCBs.  40-V to 80-V adjustable output…
