Online Capabilities for Rigid PCBs and Flex Circuits

Listed below is a list of our printed circuit board and flexible circuit board capabilities available at InstantPCBQuote. The fast, easy, 24/7 online PCB quote and ordering tool.


The Highest Technology PCBs Available Online

We pride ourselves on the ability to deliver the highest quality circuit board and flexible circuit manufactured for some of the most demanding applications in a variety of industries. We offer many options you won’t find on any other circuit board manufacturers’ websites.

All online orders also receive a full DFM review by an actual CAM engineer. If your circuit board can’t be manufactured due to a design flaw detected, we won’t just build board that won’t work. If this scenario occurs, a member of our engineering will reach out to you to help resolve the issues be manufacturing beings. This is the level of service you get when working with a circuit board fabricator with more than 65 years of experience manufacturing high-technology PCB designs.


Rigid Circuit Board Options Available Online

Our online rigid circuit board offering focuses on 8-layer PCB designs and up. With higher layer counts, we also offer larger pre-production and production quantities. Whether you need a 12-layer PCB designed with a high-temperature laminate, via-in-pad, and plated edges, we have every option covered.
