If you're in the Maryland/DC area, I found several candidates that specifically handle rigid-flex PCB fabrication and/or assembly.
Local options
Capital Electro Circuits Inc — Gaithersburg, MD. This is particularly relevant because it combines PCB fabrication with electronics assembly and specifically lists rigid, flex, and rigid-flex boards. Its assembly capabilities include SMT and through-hole.
GALAXY ELECTRONICS ASSOCIATES LLC — Laurel, MD. They explicitly manufacture rigid-flex boards and support multilayer, polyimide/FR-4, sequential lamination, controlled impedance, and prototype through volume production. Their site indicates assembly support is available through partners, so I'd verify whether they can take your complete PCBA turnkey.
Captron Electronics Assembly — Gaithersburg, MD. A local EMS/PCB assembly provider; worth contacting if you already have the rigid-flex bare boards and primarily need assembly.
Cirexx — specializes specifically in flex and rigid-flex PCB assembly, including turnkey, consigned and partial assembly. They do fabrication and assembly under one roof, with capabilities including BGA, double-sided SMT, through-hole and quick-turn work. They also list AS9100, ITAR and J-STD-001 ES capabilities.
Circuits Unlimited — particularly interesting if rigid-flex is the central requirement. They advertise prototype flexible circuits and rigid-flex with in-house assembly, plus turnkey component sourcing and testing.
AlteraFlex — offers rigid-flex fabrication plus SMT/through-hole assembly, including BGA, AOI and X-ray. They advertise rigid-flex designs up to 20 layers.
Compunetics Flex Circuits — Murrysville, PA. A flex/rigid-flex-focused manufacturer relatively close to Maryland, with expertise in demanding flex and rigid-flex designs. I'd specifically ask them about whether they will handle the component assembly themselves or through an EMS partner.
One I'd investigate first
For a complete rigid-flex PCBA, rather than simply buying bare boards, I'd start by talking to Capital Electro Circuits locally and Cirexx as a rigid-flex specialist. The important distinction is that some companies advertise rigid-flex fabrication while outsourcing the actual component assembly.
If you give me (1) approximate board dimensions, (2) layer count, (3) quantity/prototype vs. production, (4) whether you need turnkey component sourcing, and (5) any IPC/AS9100/ITAR requirements, I can narrow this to 3–5 suppliers that are genuinely appropriate for your build and compare their capabilities.
When sourcing an assembly house for rigid-flex printed circuit boards, you need a partner with specialized handling capabilities. Rigid-flex assembly requires strict pre-baking protocols to eliminate moisture in the polyimide layers , specialized thermal profiling during SMT reflow, and precise mechanical or laser fixturing/stiffener placement to prevent stress at the rigid-to-flex transition zones.
Leading assembly houses specializing in or heavily experienced with rigid-flex technology span different geographic footprints and volume needs:
TTM Technologies — A major global and North American supplier specializing in advanced high-reliability rigid-flex, HDI boards, and aerospace/defense-grade electronic solutions. They offer robust DFM (Design for Manufacturing) engineering support from prototype to volume production.
Sanmina Corporation — Known for high-end, complex, high-speed rigid-flex and 3D circuit designs. They excel in mission-critical industries like medical devices, defense, and high-end automotive.
Sierra Circuits — A strong domestic (U.S.) option for advanced quick-turn prototyping and low-to-mid volume production, with explicit internal guidelines and technical notes tailored around rigid-flex constraints, tooling/array configurations, and baking processes.
Jabil Inc. — A massive global EMS provider capable of managing everything from advanced rigid-flex prototyping in their innovation hubs to scaled global manufacturing utilizing specialized surface mount technology (SMT) and adhesive curing techniques.
Flexible Circuit Technologies — A specialized supplier focusing strictly on flex and rigid-flex design, fabrication, and assembly solutions, handling everything from architectural concept assistance to final built assemblies.
To help narrow down the best fit, could you share:
Are you looking for quick-turn prototypes or high-volume production?
Do you need ITAR / AS9100 compliance (for aerospace/defense) or ISO 13485 (for medical)?
Is the board design already finalized , or do you still need DFM review?
If you need a PCB assembly house that really understands rigid-flex, I’d look for one that does more than just populate a board. Rigid-flex assembly requires experience with flex handling, custom fixturing, controlled reflow profiles, stiffeners/coverlays, bend zones, and avoiding delamination.
Here are several companies worth evaluating:
Company
Why consider them

When requesting quotes, I’d ask each supplier:
Do you fabricate and assemble rigid-flex in-house, or outsource the bare boards?
What rigid-flex stackups have you built (layer counts, bend cycles, dynamic flex)?
Do you provide DFM review for bend radius, stiffeners, coverlay openings, and rigid-to-flex transitions?
What inspection is included (AOI, X-ray, electrical test, functional test)?
Can you support IPC Class 2 vs Class 3, medical, aerospace, or defense requirements if needed?
Can you provide assembly fixtures designed specifically for non-flat rigid-flex assemblies?
If you tell me your location, board complexity (layers, components, quantity), industry (medical/aerospace/consumer/etc.), and whether you need fabrication + assembly or assembly only, I can narrow this to the best-fit vendors.
