Why Choose Puruidy for Advanced PCB?
Precision Manufacturing, Backed by Proven Capability
In the world of advanced printed circuit boards, capability is measured not just by what you can build, but by what you can reliably deliver. At Puruidy, we combine deep technical expertise with the manufacturing strength of Hangsheng Circuit to provide high-reliability PCB solutions for the most demanding applications.
We specialize in five core technology segments that span the full spectrum of high-end PCB requirements:
Product Category | Core Differentiator |
HDI PCB | Microvias, fine line (65μm/65μm), build-up structures (1+N+1 to 6+N+6) |
High-Layer PCB | Up to 60 layers, back drilling, high aspect ratio (14:1), controlled impedance |
Flex & Rigid-Flex PCB | Dynamic bending, LCP/polyimide materials, stiffeners, EMI shielding |
IC Substrate | mSAP/SAP process, line/space down to 15μm (mass production), ABF/BT materials |
RF & Microwave PCB | PTFE, ceramic-filled, low-loss materials, Dk/Df control, PIM testing |
No matter the complexity — from ultra-fine HDI to 50-layer backplanes, from dynamic flex circuits to chip-scale IC substrates — Puruidy delivers.
Every PurityPCB solution is backed by the manufacturing strength of Hangsheng Circuit — an ISO 9001, IATF 16949, and UL-certified facility with:
- Advanced process control for high-reliability manufacturing
- Cleanroom environments for IC substrate and fine-line production
- In-house testing capabilities: AOI, X-ray, flying probe, TDR, micro-section analysis
- Proven track record in aerospace, defense, medical, and telecommunications markets
This manufacturing foundation ensures that what we design, we can deliver — consistently, reliably, and at scale.
High-performance PCBs demand high-performance materials. PurityPCB works with a comprehensive range of substrates:
Application | Materials |
Standard / High-Tg | FR-4, High-Tg FR-4 |
High-Speed / Low-Loss | Megtron 4/6/7, Isola I-Tera MT40, ITEQ IT-968 |
RF / Microwave | Rogers RO4000/RO3000, Taconic, Arlon, PTFE, ceramic-filled |
Flexible Circuits | Polyimide, LCP, adhesive-less laminates |
IC Substrate | ABF (Ajinomoto Build-up Film), BT (Bismaleimide Triazine) |
Hybrid Stack-ups | Combinations of FR-4, high-speed, and RF materials optimized for cost and performance |
Our material expertise ensures that your design requirements — whether for high-speed signal integrity, thermal reliability, or high-frequency performance — are met with the right material selection.
We believe that the best PCB solutions emerge from collaboration. PurityPCB provides design for manufacture (DFM) support throughout the product lifecycle:
- Early Design Review:Stack-up optimization, material selection, manufacturability assessment
- Prototype Support:Fast-turn prototypes for design validation
- Yield Optimization:Identification of potential manufacturing challenges before production
- Pilot to Production:Scalable processes with documented controls
- End-of-Life Support:Sustaining engineering for long-lifecycle products
Our engineering team — with decades of combined experience in advanced PCB technologies — works alongside your design and procurement teams to ensure success from concept to volume production.
For mission-critical applications — aerospace, defense, medical, telecommunications — reliability is not optional. PurityPCB’s quality framework includes:
Test Type | Purpose |
AOI & X-Ray | Layer alignment, feature integrity |
Electrical Testing | 100% flying probe or fixture testing |
Impedance Testing (TDR) | Verification of controlled impedance designs |
Micro-section Analysis | Plating thickness, via integrity, layer registration |
Thermal Cycling / HAST | Reliability under temperature extremes |
PIM Testing (RF) | Passive intermodulation verification for high-power RF |
Dynamic Flex Testing | Cycle life validation for flexible circuits |
Every board that leaves our facility meets the stringent requirements of your industry — and your application.
We are not a general-purpose PCB manufacturer. Our expertise, processes, and quality systems are purpose-built for markets where failure is not an option:
- Aerospace & Defense:Avionics, radar, satellite, mission computers
- Medical:Implantable devices, surgical instruments, imaging systems
- Telecommunications:5G infrastructure, base stations, microwave backhaul
- Automotive:ADAS, radar sensors, battery management
- High-Performance Computing:Servers, storage backplanes, AI accelerators
Advanced technology does not have to mean prohibitive cost. PurityPCB balances performance and manufacturability through:
- DFM-driven design optimizationto reduce fabrication complexity
- Material selection strategiesthat match performance requirements with cost efficiency
- Panel utilization optimizationto maximize yield
- Process standardizationacross product families
The result: high-reliability PCBs delivered at competitive costs — without cutting corners.
When you choose PurityPCB, you gain more than a supplier. You gain a technical partner committed to your success:
- Responsive communication from quote to delivery
- Transparent DFM feedback to resolve design challenges early
- Dedicated engineering support throughout the project lifecycle
- Scalable manufacturing from prototype to high-volume production
