Board Fabrication

Printed Circuit Design and Fabrication Services

Acorn Assembly offers customized solutions for board fabrication needs. Instead of wondering if you’re getting the best price or the best quality from a single board shop, talk with our custom PCB fabrication experts.

We work with a small group of highly qualified U.S. board fabrication companies that can meet the requirements of most any design. From simple 2-layer boards to complex HDI (High Density Interconnect) designs, we provide quality bare boards at competitive prices and lead times.

Ordering and Production

Acorn Assembly provides high-quality custom fabrication and assembly of printed circuit boards for a competitive price and turnaround time. This is thanks, in part, to our hassle-free ordering and production process. Here’s how it works.

Our account managers will respond to your inquiry with you within minutes. We’ll need a few details from you to get your quote started:
- The number of assemblies you need
- Your bill of materials, design files, and other specific details like fabrication and assembly instructions
- Your target lead time
- Any other special requirements


Place your order and payment and we’ll send a confirmation immediately. Our engineers will also review your files for any inconsistencies. We’ll reach out to you immediately if there are any. If not, we’ll start.

Receiving First Articles

First articles are a small portion of your prototype assembly order and a good way for a last double check of your design before having a whole order completed. If you would like, we’ll send a small set of assembled units to you for double-checking and approval before manufacturing the rest of the PCBs. If you find any problems with them, get in touch with us. We’ll make the necessary revisions immediately.

Getting the Rest of Your Order

Once you’re happy with the first articles or the revised design, we’ll finish the assembly of the balance of your circuit boards.
