0.4mm FR4 Red EING PCB

Mulitilayer material unlike double-sided pcbs with only two conductive layers all multilayer pcbs is that it must have at least three layers of conductive material, and the pcb boards are buried in the center of the material.this design is  4 layer  0.4mm enig red solder pcb.0.4mm for 4 layer pcb?yes,the thickness most of fabricate can't fabricate them.storm can  fabricate 4 layer pcb with 0.4mm red solder enig pcb.
