China Wholesale Fast Pcb Prototyping Suppliers - 8 layer HASL PCB circuit board – Huihe

Why are multilayer boards mostly even?

Due to the lack of a layer of medium and foil, the cost of raw materials for odd PCB is slightly lower than that for even PCB. However, the processing cost of odd layer PCB is significantly higher than that of even layer PCB. The processing cost of the inner layer is the same, but the foil/core structure significantly increases the processing cost of the outer layer.

Odd layer PCB needs to add non-standard lamination core layer bonding process on the basis of core structure process. Compared with the nuclear structure, the production efficiency of the plant with foil coating outside the nuclear structure will be reduced. Prior to lamination, the outer core requires additional processing, which increases the risk of scratches and etching errors on the outer layer.
