PCB Fabrication Overview

At ANKE PCB, standard PCB services refer to full-featured printed circuit board manufacturing services. With over 10 years PCB manufacturing experiences, we have handled thousands of PCB projects covering almost every type of substrate material including FR4, Aluminum, Rogers and more. This page only refers to standard FR4 based PCBs. For PCBs with special technical substrates, please refer to the corresponding web pages for information or feel free to drop us mail at info@anke-pcb.com.

Different with pcb sampling, standard PCB has tighter production tolerances and more stable production quality.

Standard PCB services are recommended when your design is ready to transform from prototype to production. We can produce up to 10 million high quality PCBs in just 2 days. To give your project the desired functionality and more possibilities, we offer advanced features for standard PCB services. The comprehensive ability is shown as below:
