Vist our Profeceial Process of Manufacturing
PCB manufacturing is a complex process of many steps Each PCB has a unique function for a particular product. Check for main steps of multilayer PCB manufacturing. At PCBBUY, we promise to guarantee the quality of our boards through a product specification and quality control. In the production flow below you can see where the PCBBUY process is unique up to the IPC standard.
