PCB Fabrication Technologies in India

India’s PCB fabrication sector includes rigid, flexible, and rigid-flex boards, with multilayer and HDI technologies growing rapidly. Advanced laminates, high-frequency substrates, and precision etching techniques support PCBs for smartphones, automotive electronics, and industrial applications. Leading companies such as Fine-Line Circuits and Shogini Technoarts are investing in automated fabrication lines to improve throughput, precision, and consistent quality.

Automated PCB Assembly Services

Automation is increasingly critical in PCB assembly to meet India’s growing electronics demand. Pick-and-place machines, soldering robots, and advanced testing systems reduce errors, improve efficiency, and shorten lead times. In this context, Haier India announced in 2023 a Rs 800 crore investment to expand air-conditioner production and establish a PCB manufacturing unit. This facility will increase AC production from 1.5 million to 2.5 million units annually, strengthening Haier’s presence in India’s home appliance market while demonstrating the role of automated PCB assembly in scaling domestic electronics manufacturing.

Surface-Mount Technology (SMT) Trends

SMT remains the dominant assembly method due to miniaturization, high-speed production, and versatility. Indian manufacturers are adopting AI-enabled inspection systems, automated optical inspection (AOI), and solder paste inspection (SPI) to improve yield and defect detection. SMT enables higher component density and reliability, especially for consumer electronics, automotive, and industrial applications.

PCB Prototyping and Small-Batch Production

Rapid prototyping and small-batch PCB production are vital for startups and OEMs testing new designs. Agile manufacturing processes allow iterative design improvements, shorter lead times, and cost-effective production runs. These services support high-tech sectors such as IoT devices, wearables, and medical electronics.

Indian PCB Contract Manufacturers

Contract manufacturing is expanding as EMS (Electronics Manufacturing Services) providers offer end-to-end solutions from design support to full-scale assembly. Companies like Kaynes Technology and SFO Technologies provide turnkey services for rigid, flexible, and HDI PCBs, catering to domestic and export markets.  In June 2025, Zetwerk, a Bengaluru-based unicorn, announced investment plans of INR 500–800 crore to expand into manufacturing printed circuit boards (PCBs), enclosures, and electromechanical components such as heat sinks and sensors. Such investments in automation and precision fabrication further strengthens India’s competitiveness in global PCB supply chains.

Market Outlook and Strategic Opportunities

India’s PCB manufacturing and assembly sector is expected to grow steadily through 2034. Key drivers include automation, SMT adoption, contract manufacturing, and prototyping services. Specialized PCBs for electric vehicles, IoT devices, and medical electronics will see rising demand. Sustainable manufacturing practices, local sourcing, and energy-efficient production will enhance resilience, reduce import dependency, and support India’s emergence as a global electronics manufacturing hub.
