6 Layer Green Solder EING PCB

Benefits of multilayer pcbs (compared to single or double-sided pcbs),higher assembly density,smaller size (considerable savings on space),increased flexibility.for 6 layer pcb with 3 work days  to finish.this design is 6 layer pcb with outer 2oz and inner 2oz.the pcb thickness is 1.6mm and min holes is 0.15mm.the most  important it is 6 layer enig pcb.our factory just send  our client this design within 3 days.
