PCB assemblies are the backbone of modern electronics, powering everything from smartphones to satellites. Yet, behind every successful circuit board assembly lies a complex web of regulations that manufacturers must navigate to ensure both legal operation and market access. In the United States, two of the most critical compliance pillars for turnkey PCB assembly are ITAR (International Traffic in Arms Regulations) and RoHS (Restriction of Hazardous Substances).
For PCB assembly providers in the USA, meeting these standards is not just a box-ticking exercise—it is a fundamental requirement for participating in defense, aerospace, and global electronics markets. Compliance impacts every stage of the process, from material sourcing to final shipment. This blog unpacks what ITAR and RoHS mean for circuit board assembly, highlights their key differences, outlines best practices, and addresses common challenges faced by U.S.-based manufacturers.
A Closer Look at ITAR and Its Role in U.S. PCB Manufacturing
What Is ITAR?
ITAR stands for International Traffic in Arms Regulations, a set of U.S. government rules that control the export and import of defense-related articles and services. The U.S. Department of State, specifically the Directorate of Defense Trade Controls (DDTC), administers ITAR. Its primary goal is to prevent sensitive military technologies from falling into the wrong hands, safeguarding national security.
What PCB Assemblies Fall Under ITAR?
PCB assemblies designed for military, aerospace, and defense applications are often classified as ITAR-controlled. This includes, but is not limited to:
- Satellite boards
- Guidance systems
- RF (radio frequency) modules
Any circuit board assembly that is specifically designed for use in defense articles listed on the United States Munitions List (USML) is subject to ITAR. Even technical data, such as fabrication drawings and netlists, can be ITAR-controlled.
What ITAR Compliance Requires
- Registration: Companies must register with the DDTC before engaging in ITAR-related manufacturing or export activities.
- Documentation: Detailed records of all transactions, technical data transfers, and physical movements of ITAR-controlled items must be maintained for audit purposes.
- Secure Data Handling: Only U.S. persons may access ITAR-controlled data, and secure IT systems are required to prevent unauthorized access.
- Export Licensing: Manufacturing or exporting ITAR-controlled PCBs often requires obtaining specific licenses from the U.S. government.
- Facility and Labor Requirements: Facilities may need export-restricted zones, and all involved personnel must be U.S. persons. This impacts hiring, training, and facility access policies.
Understanding RoHS and Its Growing Relevance in the U.S.
What Is RoHS?
RoHS stands for Restriction of Hazardous Substances. Originating as an EU directive, RoHS restricts the use of ten hazardous materials—including lead, cadmium, mercury, and certain phthalates—in electrical and electronic equipment. The aim is to reduce environmental impact and health risks associated with electronic waste.
How RoHS Applies to PCB Assembly
- Lead-Free Soldering: PCB assembly lines must use lead-free solder alloys, such as tin-silver-copper, and avoid fluxes containing restricted substances.
- Material Selection: All base materials, finishes (e.g., ENIG), and components must be RoHS-compliant. Suppliers must provide documentation confirming this compliance.
- Labelling and Testing: Each shipment of RoHS-compliant circuit boards should include a Certificate of Conformance and clear labelling. X-ray fluorescence (XRF) analyzers may be used to verify the absence of restricted substances.
- Vendor Compliance: Manufacturers must ensure that all components and materials sourced are RoHS-compliant, often requiring supplier audits and documentation checks.
U.S. Adoption and Global Trade Considerations
Although RoHS began as an EU regulation, it has been adopted in various forms worldwide. In the U.S., states like California have implemented their own RoHS laws, and the Waste Electrical and Electronic Equipment (WEEE) directive also influences domestic practices. U.S. manufacturers follow RoHS to access international markets and meet global customer expectations.
ITAR vs. RoHS—Understanding the Key Differences
| Aspect | ITAR | RoHS |
| Scope | National security, defense, military | Environmental health and safety |
| Applicability | Military, aerospace, defense sectors | Consumer, industrial, all electronics |
| Enforcement | U.S. Department of State (DDTC) | EU authorities, U.S. state agencies |
| Penalties | Severe fines, export bans, prosecution | Fines, product recalls, market bans |
| Overlap | Possible for military boards exported abroad—may require both ITAR and RoHS compliance (e.g., lead-free military PCB) |
How U.S.-Based PCB Assembly Providers Stay Compliant
Facility-Level Requirements
- ITAR: Registration with DDTC, restricted access zones, and secure data systems are mandatory for ITAR-sensitive work.
- RoHS: Dedicated lead-free manufacturing lines, compliant soldering processes, and regular equipment audits are essential.
Documentation and Recordkeeping
- RoHS: Material declarations, Certificates of Conformance, and batch-level traceability records must be maintained.
- ITAR: Controlled technical data, access logs, and export documentation are required for every transaction and transfer.
Compliance Software and Automation
- ERP/MRP systems help track materials, manage documentation, and ensure traceability for both ITAR and RoHS requirements.
- Automated reporting aids in conflict mineral tracking and regulatory audits.
Working With Certified Partners
- Always verify a supplier’s ITAR registration and RoHS certification.
- For ITAR-sensitive projects, selecting a U.S.-based turnkey PCB assembly provider is critical to avoid unauthorized foreign access and ensure full regulatory compliance.
Real-World Scenarios and Case Examples
Example 1: A Defense Contractor Needing an ITAR-Compliant RF PCB
A U.S. defense contractor requires an RF module for a missile guidance system. Using an offshore supplier could risk unauthorized access to ITAR-controlled designs, resulting in severe penalties. The workflow involves design, secure data transfer, U.S.-person-only assembly, and detailed documentation from design to delivery—all within a registered, secure U.S. facility.
Example 2: A Consumer Electronics OEM Seeking RoHS Compliance
A consumer electronics OEM sources components from multiple vendors. To achieve RoHS compliance, the procurement team conducts supplier audits, collects Certificates of Conformance, and ensures lead-free soldering during assembly. Regular testing and documentation are maintained to satisfy EU market requirements.
Common Compliance Pitfalls—and How to Avoid Them
- Using Non-Compliant Components: Always verify supplier certifications and test materials if necessary.
- Exporting ITAR-Controlled Designs Without Licenses: Never share technical data or products internationally without proper DDTC licensing.
- Failing to Document RoHS Conformity: Maintain up-to-date records and Certificates of Conformance for all shipments.
- Relying on Unverified Vendors: Work only with certified, U.S.-based partners for ITAR-sensitive projects and demand RoHS documentation from all suppliers.
Tips for OEMs, Engineers, and Procurement Teams
- Integrate Compliance Early: Address ITAR and RoHS requirements during the design phase (DFX approach) to avoid costly redesigns or delays.
- Maintain a Vetted Supplier List: Regularly audit and update approved vendors to ensure ongoing compliance.
- Train Teams on Regulations: Provide ongoing training for engineering, procurement, and quality teams on evolving ITAR and RoHS rules.
- Monitor Legislative Updates: Stay informed about changes, such as ITAR amendments or RoHS 3 updates, to remain compliant and competitive.
