Study of multilayer inner foil brown oxide processing solution for PCB

This article provides an overview of the structure used in the multilayer PCB production process in the browning process by introducing principles and brown film. It mainly discusses a new brown treatment solution, including the recipe composition and process methods. Experiments and application practice have been proved that it is able to significantly promote the copper surface Prepreg combination of force, high-temperature thermal shock performance, high peel strength, no pink ring. The process is simple, with broad applicability, and low cost.
