Who Are The Best Printed Circuit Board Manufacturers In The US?

The top circuit board manufacturing companies in the United States have been offshoring production for decades. While finding cheap domestically produced alternatives is challenging, it is not impossible — there are many high-quality factories right here in America. Which are the best printed circuit board (PCB) manufacturers and the best PCB assembly companies?

1. EMSG

Out of all of the top circuit board manufacturing companies in the U.S., Electronic Manufacturing Services Group (EMSG) Inc. is the clear choice. This full-service company takes you from conceptualization to product launch. Its services include electronic, PCB and box build assembly. It can work with custom designs, enclosures and packaging. It also assists with testing and inspection. Upon completion, it ships to you or drop-ships directly to your customers.

If you need small to midsized batches, ESMG is ideal — it typically offers short-run productions of 50,000 units or less at a time. Its designs are exclusive to your product type. With PCBs, no one-size-fits-all solution exists — everything from a product’s shape to its power requirements influences its circuit board component requirements. However, this company pays particular attention to business-specific needs to achieve the highest performance and quality standards

EMSG serves telecom, medical, industrial, communications and electronics sectors. While it is based in York, Pennsylvania — where its 20,000 square-foot facility is located — its proximity to Route 81 allows access to the entire Eastern seaboard. Notably, since it operates in the domestic market, you can use its services anywhere in the U.S.

What makes EMSG one of the best PCB assembly companies? Its product criteria. Over its 30 years in the field, it has perfected its craft. It adheres to ISO 9001 certification, demonstrating its commitment to quality. Despite holding itself to high standards, its lead times are as fast as three weeks. Once it receives its supplies, it takes roughly one week to inspect, assemble and ship your products.

2. AdvancedPCB

AdvancedPCB is one of the best PCB assembly companies. It offers in-house design, prototyping fabrication and assembly. While it has offshore design, sales, distribution and production sites, most manufacturing and quality inspections happen within the domestic market. Despite diversifying, this manufacturer’s roots have remained firmly in place. It is one of the leading PCB manufacturers in North America but remains headquartered in Aurora, Colorado.

Peter Austin, AdvancedPCB’s chief executive officer, has been vocal about the importance of U.S. factories in the past. In an August 2024 opinion piece, he said there is “nowhere near enough focus” on domestic production at the policy-making level despite the financial incentives the government’s recent CHIPS and Science Act provided. However, despite the industry’s reliance on offshoring, Austin seemingly remains confident in a return to form.

Clearly, Austin is committed to serving its domestic customer base in the aerospace, defense, automotive, consumer electronics, telecom, computing, networking and data storage industries. Regardless of whether they need flexible, semi-flexible or rigid solutions, they can count on AdvancedPCB. This characteristic makes it one of the top circuit board manufacturing companies in the U.S.

3. TTM Technologies Inc.

TTM Technologies Inc. is among the best PCB assembly companies operating in the domestic market and is widely recognized as an industry leader. Its global headquarters are located in California. The U.S. locations include Denver, New York, Wisconsin, Colorado, California and Ohio, among other states. Maximum batch size varies from state to state, ranging from low to high-volume production.

As a publicly traded company, TTM Technologies Inc. must disclose its financials to shareholders. In a report to the U.S. Securities and Exchange Commission, it revealed its net sales exceeded $605 million in the second quarter of 2024, up roughly $58.5 million year over year. Its generally accepted accounting principles (GAAP) net income — the earnings left over after subtracting expenses from revenue — was $26.4 million for the same period.

This financial report showcases this company’s dominance in the industry, proving it is among the best printed circuit board manufacturers. These figures are positive factors for business stability. Whether you are looking for a long-term partner or seek a one-off production run, you can rest assured knowing these workers won’t cut corners or rush the process to save money.

Although this company’s size and scope are impressive, you should know that it doesn’t specialize in PCB fabrication or assembly. Its broad services cover radiofrequency components, microelectronics, signal integration and power supply solutions. While its scope does not necessarily diminish its capabilities, you could consider it a jack of all trades — and you know how that saying goes. This is one of the reasons it didn’t make first place.

4. Plexus Corp.

Plexus Corp. is an electronic manufacturing services provider that offers PCB assembly services. Like TTM Technologies Inc., its scope is expansive. It serves various businesses in the industrial, aerospace, security, communications, transportation, medical and commercial sectors. While it has a global presence, it is headquartered in Neenah, Wisconsin. Its facilities are scattered about the Pacific Northwest, Midwest and Southeast.

What makes Plexus Corp. one of the top circuit board manufacturing companies in the U.S.? For one, it offers exceptional expertise. It was founded in 1979, giving it over 40 years of experience in the industry. Moreover, it has upwards of 20,000 full-time employees, each adding their own talent to the corporation’s collective competence.

Another reason this corporation is among the best PCB assembly companies is its positive growth. Since Plexus Corp. is publicly traded, its financials are public. In the fourth quarter of 2024, it reported a 3% year-over-year revenue increase, surpassing its own estimations. Moreover, it secured over $500 million in contracts in the fiscal year 2024 (FY 2024), expanding its manufacturing opportunities to an estimated value of $3.6 billion.

This firm’s strong profit margins, decades in the industry and impressive market capitalization indicate long-term resiliency. It is an excellent choice for those needing PCB design, development, fabrication, repair and refurbishment services. Its commitment to sustainability — it has an environmental, social and governance program — is a bonus for any buyer seeking like-minded vendors.

5. Advanced Technologies & Solutions

Although Advanced Technologies & Solutions (AT&S) mainly serves aerospace and telecom, you can still use its services if you operate in the medical, communications or consumer electronics sectors. This firm’s extensive experience with miniaturization and compact product housing may make it a good option for you.

AT&S is among the best printed circuit board manufacturers because it explicitly offers flexible and rigid-flexible PCBs. You can bend, crease, fold and twist them as necessary to ensure they fit into your product’s housing — there is no risk of damage. Unlike rigid PCBs, they can fit into miniature devices or compact crevices, easily overcoming space constraints.

AT&S has a global presence, with multiple locations in various countries worldwide. Technically, it serves the domestic market, offering fabrication and assembly services to U.S. buyers like you. However, it only produces parts in its international production plants — the only facilities in this country are sales support offices.

6. Sanmina Corp.

As its financials demonstrate, Sanmina Corp. is among the top circuit board manufacturing companies in the U.S. In FY 2024, it reported over $7.57 billion in revenue, $2.02 billion of which came from its fourth-quarter earnings. Its GAAP operating margin was 4.4% and its non-GAAP operating margin was 5.4%. Maintaining its momentum through the year’s end shows it has continued delivering for its existing customers.

This corporation specializes in PCB fabrication and assembly and is one of the country’s leading manufacturers of advanced PCBs. Thanks to its size and budget, it can effectively service those who require high-volume production. Its facilities in Asia, Europe and the Americas serve the aerospace, defense, communications, medical, automotive and industrial sectors.

Sanmina Corp. is among the best printed circuit board manufacturers in the U.S. because it offers in-house material certification, multilayer manufacturing, thru-hole technology and laser milling. Like EMSG, it is a full-service company that provides development, testing and prototyping services. Although its interactions may not be as intimate or personable as those at small and midsized companies, it can achieve quick turnaround times for large batches.

These Are the Best of the Best PCB Assembly Companies

The federal government subsidized the domestic production of electronics and electronic components with the CHIPS and Science Act, suggesting this list may soon grow much longer. While the top circuit board manufacturing companies in the U.S. will likely continue dominating the market, there is always room for more quality PCB assembly companies.
