Functional Advantages

HYBRID RIGID-FLEX STRUCTURE
 
Combines FR-4 rigid sections for stable component mounting with polyimide flexible sections for dynamic bending areas. This hybrid design enables 3D assembly in tight spaces, eliminating the need for bulky connectors and cables while reducing total assembly volume by up to 30%.

ULTRA-THIN & LIGHTWEIGHT PROFILE
 
Flexible sections as thin as 0.1mm with a total stack-up thickness as low as 0.3mm. Compared to traditional rigid PCBs, our Rigid-Flex PCBA reduces device weight by up to 40%—perfect for portable and wearable electronics where every gram matters.

EXCEPTIONAL BENDING DURABILITY
 
Engineered to withstand ≥10,000 bending cycles at 5mm radius and 90° angle without signal loss or mechanical failure. Ideal for dynamic applications such as fitness trackers, foldable devices, and robotic arms that require repeated flexing.

HIGH-FREQUENCY SIGNAL INTEGRITY
 
Controlled impedance (±10% tolerance) and integrated EMI shielding ensure stable high-frequency performance up to 20GHz. Our precision engineering supports 77GHz millimeter-wave radar applications with 15% less signal loss compared to traditional connector-based assemblies.

ENHANCED RELIABILITY & REDUCED FAILURE RATES
 
Optimized flex-to-rigid transitions minimize solder joint stress, reducing failure rates by 60% in vibration-prone environments. Our advanced AOI and X-ray inspection systems ensure hidden solder joint quality for BGA/CSP components.

Core Applications

MEDICAL DEVICES & IMPLANTABLES
 
Our ISO 13485 certified Rigid-Flex PCBA powers life-critical medical electronics, including cardiac pacemakers, insulin pumps, EEG/ECG monitors, and minimally invasive surgical tools. With biocompatible polyimide substrates, ultra-thin 0.2mm flex sections, and low-noise circuitry (<50μV interference), we deliver the precision and reliability that medical device manufacturers demand. Sterilization-compatible designs withstand ETO and autoclave processes for implantable and reusable surgical instruments.
 
AUTOMOTIVE ELECTRONICS & ADAS SYSTEMS
 
IATF 16949 compliant Rigid-Flex PCB assemblies for next-generation automotive applications. Our 77GHz millimeter-wave radar PCBA with integrated rigid-flex antenna reduces signal loss by 15%, while AEC-Q100 Grade 2 qualification ensures reliable operation from -40°C to +150°C. Applications include ADAS radar modules, occupant detection sensors, in-cabin monitoring systems, and dashboard-integrated electronics meeting EU NCAP safety requirements.
 
WEARABLE TECHNOLOGY & CONSUMER ELECTRONICS
 
Ultra-thin Rigid-Flex PCBA (total thickness 0.3mm) enables sleek, lightweight designs for smartwatches, fitness trackers, AR glasses, and VR headsets. Our flexible battery connections bend with wrist movement without signal loss, while IPC-CC-830 conformal coating protects against sweat and skin oils—extending product lifespan by 2+ years. Biocompatible materials (ISO 10993-5) ensure skin-safe contact for health monitors and fitness bands.

FAQ

Q1:If I make an order PCB+Assembly, can I send components to Tdt-ele directly? (Consigned Parts)?
A: Tdt-ele offers consigned component services (customer-provided ), in addition to turnkey PCBA solutions. This suits hard-to-source or long-lead-time parts, but customers bear freight, customs fees, and clearance responsibilities. Tdt-ele assumes no liability for transit issues (seizure, damage, loss) or delays from pending parts.
 
Unfamiliarity with regional customs or inadequate part preparation may cause costly delays. Thus, we strongly recommend avoiding consigned parts unless necessary. For hard-to-source components, first explore alternatives (substitute parts or alternative suppliers).
