Technical capabilities

Built for complexity
and extreme reliability

Every board we produce is engineered to perform under the most demanding conditions — extreme temperatures, high vibration, continuous high-current loads.

01
Heavy copper fabrication
Specialized processes for high-current applications, ensuring optimal thermal management and power distribution across demanding environments.
→ Up to 15oz copper weight → High-current bus bars → Thermal management optimized
02
High-density multilayer boards
Advanced lamination and via structures supporting complex, high-density architectures for sophisticated electronic systems.
→ Up to 30 layers → Blind and buried vias → HDI capable
03
Diverse surface finishes
Comprehensive range including ENIG, HASL (Lead-Free & Leaded), OSP, Immersion Silver, Immersion Tin, Hard and Soft Gold, Gold finger, and ENEPIG.
→ 10+ finish options → Application-tailored selection
04
High-reliability architecture
Boards engineered to withstand extreme environmental stress — vibrations, temperature cycling, and harsh operating conditions over extended lifetimes.
→ IPC Class 3 certified → Thermal cycling tested → HALT/HASS compatible
05
Precision etch compensation
Advanced manufacturing techniques ensuring exact trace geometries and tight dimensional tolerances for complex, high-density power designs.
→ Min trace/space 3mil → Controlled impedance → Tight dimensional tolerances
06
Pre-emptive DFM review
Manufacturability review conducted once files are received — identifying potential issues early so they're resolved before production begins, not during it.
→ IPC Class 3 DFM standard → Early-stage issue detection → Faster time to production

Industries served

Powering the energy transition

Our boards are deployed across industries where high-power, high-reliability electronics are foundational — not optional.

01
Electric vehicles
Heavy copper solutions for EV powertrains, battery management systems (BMS), onboard chargers, and high-performance DC-DC converters.
02
Battery & energy storage
BESS control boards, grid-scale lithium pack management, and high-current protection circuits for stationary and mobile energy storage systems.
03
Renewable energy
Solar inverter control boards, wind turbine power electronics, and grid-tie converter platforms optimized for continuous high-power operation.
04
Industrial power electronics
Motor drives, variable frequency drives (VFDs), power converters, and complex feedback control systems for industrial automation and robotics.
05
Medical equipment
High-reliability boards for imaging systems, surgical equipment power supplies, and patient-critical monitoring hardware requiring IPC Class 3 standards.
06
Railways & mass transit
Traction control, signaling, and power management boards engineered for the vibration, temperature extremes, and longevity demands of rail applications.

How we work

Straightforward.
No surprises.

A clear, structured process from first enquiry to delivery — so you always know where your order stands and what comes next.

STEP 01
Order placement & file review
Once your order is placed and design files are received, we conduct a thorough manufacturability review against IPC Class 3 standards before committing to production.
Files → review
STEP 02
Streamlined EQ process
If engineering queries arise, we raise them promptly in a single consolidated round — no drip-feed of questions. Most EQs are resolved within 24–48 hours so production isn't held up longer than necessary.
Fast turnaround
STEP 03
IPC Class 3 manufacture
Production with full AOI, X-ray, and flying probe inspection. Complete traceability documentation at every stage of fabrication and assembly.
Full traceability
STEP 04
On-time global delivery
Strategic logistics from Mumbai with all export documentation, certifications, and customs compliance handled. DDP and DAP terms available.
Global supply chain

About SRPCB

Engineering-driven.
Uncompromising.

SRPCB is the PCB division of SR Exports, headquartered in Mumbai, India. We specialize in high-reliability printed circuit boards for mission-critical power and energy applications.

We were built around a fundamental observation: the traditional handoff between hardware design teams and volume manufacturing is broken. Engineering holds, communication loops, and late-stage DFM failures routinely cost weeks — and programmes.

Our approach is to intercept the supply chain early. By embedding IPC Class 3 compliance and manufacturing constraints directly into pre-production planning, we give hardware teams greater predictability over their platforms.
