Accelerated fabrication and assembly with faster lead times — ideal for prototype validation and engineering builds.
Yes. Small-batch and low-volume builds are our specialty.
Yes. All fabrication and assembly occur in our US-based, ISO 9001 certified, ITAR registered facility.
Quotes in 24 hours; production in 5–10 days with expedited options available.
To provide a quote for a PCB Assembly project, we typically need the following information: Gerber files for the PCB design, a Bill of Materials (BOM) with component details, assembly drawings, a pic-n-place file (Centroid if available), and any special requirements or instructions you might have for your assembly.
Yes, we absolutely can. We are fully equipped to manage the RoHS (Restriction of Hazardous Substances) compliant PCB assembly process. This means we ensure that the assembly process and all components used comply with the regulations set out by RoHS, which limits the use of specific hazardous materials in electronic equipment.
We understand the importance of environmental responsibility in electronics manufacturing and are committed to meeting the highest safety and sustainability standards. Therefore, we can confidently offer our customers RoHS-compliant PCB assembly services without compromising on quality or performance. If you have specific requirements or need further information regarding our RoHS-compliant processes, please do not hesitate to get in touch with us.
We take great pride in the various certifications and memberships that affirm our commitment to delivering high-quality, reliable PCB assembly services. Our company is:
• ISO 9001:2015 certified, indicating our dedication to quality management and continuous improvement.
• ITAR registered, showcasing our ability to handle projects related to defense and military applications.
• UL Registered, verifying our products’ safety and compliance with established industry standards.
• IPC member, applying standards that increase our quality of assembly, as well as keeping up with the best practices in the electronics industry.
• RoHS-compliant, underscoring our commitment to environmental responsibility and the reduction of hazardous substances when our customers require that compliance.
We strive to maintain these qualifications to provide the highest level of service to our customers, ensuring peace of mind with every project.
The quality control process typically involves visual inspection, Automated Optical Inspection (AOI), and X-ray inspection. In addition, you can request, and we can provide additional post-assembly testing, including Flying Probe Testing, In-Circuit Test (ICT), or Functional Circuit Test (FCT), depending on the complexity of the boards and your requirements.
Yes, we are proud to offer comprehensive turnkey PCB assembly services. This means we handle the entire process from start to finish, allowing you to place a single order and receive fully assembled boards. Our turnkey service includes PCB fabrication, component procurement, assembly, quality control, and testing.
Absolutely, we accommodate that scenario. We understand that our customers sometimes have specific, potentially hard-to-source electronic components or pre-manufactured boards that they wish to use. We are fully prepared to integrate these into the assembly process. Our objective is to offer maximum flexibility to meet your unique needs and ensure the final product aligns with your expectations. Please ensure to communicate this requirement at the project’s outset so we can best accommodate your needs.
Yes — Acorn specializes in low-volume and small-batch PCB fabrication and assembly for engineering prototypes and production validation runs.
Reliable, accurate, quick-turn PCB fabrication & assembly for engineers who need speed and precision, MADE in USA.
