Our fast-track process prioritizes your order without compromising the precision and quality you need for meaningful evaluation. We make prototype boards ready for testing, validation, or immediate production launch.
Quality Assurance & Certifications	Every Rigid-Flex Printed Circuit Board we manufacture undergoes multiple inspection and testing stages. Our quality management system ensures traceability from incoming materials through final shipment. We maintain detailed records for every production lot, providing the documentation you need for regulatory compliance or failure analysis. Our Certifications: ISO 9001:2008 Certified Quality Management System UL Recognition for PCB Manufacturing RoHS Compliant Materials and Processes IPC Class 3 Manufacturing Standards (Highest Reliability Level) ITAR Registered for Defense Applications

Our RF Microwave PCB Fabrication Process

As a process-driven rigid FR4 PCB manufacturer, we follow a systematic approach that ensures consistency and quality at every stage.

Design Review & Stackup Planning

Our engineers analyze your design files, identifying potential manufacturability issues before production begins. We optimize bend radius locations, recommend appropriate materials, and configure stackups for reliability. This upfront collaboration prevents costly revisions later.

Material Preparation & Lamination

We carefully select and prepare rigid and flexible substrates based on your application requirements. Hybrid bonding requires precise alignment and controlled pressure/temperature profiles. Our lamination process creates strong, reliable bonds between dissimilar materials.

Drilling, Plating & Etching

Advanced laser drilling systems create accurate microvia structures with minimal heat-affected zones. Mechanical drilling handles through-holes and larger vias. Our plating process ensures uniform copper deposition, even in challenging high-aspect-ratio vias. Precision etching defines your circuit patterns with tight tolerances.

Coverlay & Stiffener Application

Flexible regions receive protective coverlay lamination, while stiffeners reinforce areas that need additional mechanical support. We control lamination parameters to prevent damage to sensitive flex circuits.

Solder Mask & Surface Finish Application

We apply solder mask to rigid sections using photoimaging processes that deliver accurate registration. Surface finishes are applied according to your specifications, whether you need wire-bondable gold or standard ENIG.

Profiling & Singulation

CNC routing or laser cutting separates individual boards while maintaining clean edges on flex sections. We use specialized tooling that prevents delamination during cutting operations.

Inspection & Testingn

Every board undergoes comprehensive inspection: Automated Optical Inspection (AOI), X-ray imaging for internal structures, cross-section analysis for quality verification, and 100% electrical testing. We manufacture to IPC Class 3 standards, the highest reliability level for critical applications.

Industries and Applications

We serve diverse sectors where reliability isn't negotiable. Here are some of our application areas.

Aerospace & Defense: Lightweight, vibration-resistant rigid-flex assemblies are used in avionics, satellites, and mission-critical military systems. Our boards withstand extreme temperatures, shock, and electromagnetic interference.

FAQs

What design files do you need to provide a quote?

We work with standard Gerber files (RS-274X), ODB++, or native design files from major PCB layout tools. Include a detailed stackup specification, material requirements, finish specifications, and any special instructions. A fabrication drawing with dimensions, layer counts, and notes is helpful. We can also work from preliminary specifications if you need early cost estimates.

Do you support small prototype quantities?

Yes. Many customers start with a small batch before scaling to production.

What's the typical lead time for rigid-flex PCB prototypes?

Standard prototypes typically take 10-15 business days, but we offer expedited services that can deliver within 5-7 days, depending on the complexity of the project. Quick-turn orders may have layer count or size limitations. Contact us with your specific requirements for an accurate timeline.
