A worker on Dixon Technologies’ assembly line in Noida now helps build a smartphone that could ship to any of a dozen global brands — Samsung, Motorola, Xiaomi, Google — without the customer ever knowing an Indian factory touched it. That anonymity is precisely the business model, and it’s scaling faster than almost anyone predicted. India’s electronics manufacturing sector, valued at roughly $155 billion in 2024, is tracking toward $500 billion by 2030 at a 21.5 percent CAGR, according to Niti Aayog projections. Apple alone now manufactures 15 percent of global iPhones in India, targeting 25 percent by FY28, and every percentage point of that shift generates an estimated $800-900 million in downstream supply chain revenue for Indian EMS players. Here’s who’s actually building the electronics behind that boom.
1. Dixon Technologies
Dixon’s growth curve reads almost implausibly steep — sales hit ₹38,880 crore in FY2024-25, up 119 percent from ₹17,691 crore the year before, on the back of relentless capacity expansion across product categories. Founded in 1993 making colour TVs, the company now runs India’s largest LED TV facility in Tirupati, its largest washing machine plant in Dehradun, and major LED lighting production in Noida, all while remaining genuinely net debt-free — a rarity in a capital-intensive manufacturing sector.
Dixon’s next move is backward integration into display modules, camera components, and batteries, a deliberate push to capture more value per device rather than staying a pure assembly business. It recently signed to manufacture smartphones for Xiaomi India and entered laptop production through a PLI-backed partnership with US and Chinese firms, broadening its footprint well beyond its original TV-and-lighting roots.
2. Foxconn India
Foxconn operates as the world’s largest contract electronics manufacturer, and its Indian operations, concentrated across Tamil Nadu and Andhra Pradesh, form the backbone of Apple’s growing India-based iPhone production. As Apple diversifies away from near-total China dependence, Foxconn’s Indian facilities have become central to that strategy rather than a peripheral experiment.
The scale here matters beyond Foxconn’s own balance sheet — every iPhone assembled in India pulls a web of Indian component suppliers, logistics providers, and sub-assembly manufacturers into Apple’s global supply chain, indirectly benefiting the entire domestic EMS ecosystem well beyond Foxconn’s own factory walls.
3. Amber Enterprises
Amber built its business as the dominant room air conditioner component manufacturer in India, then began deliberately expanding into electronics components — printed circuit board assemblies specifically — through its most ambitious move yet: ₹4,200 crore committed across two projects under the Electronics Component Manufacturing Scheme, including a ₹3,200 crore joint venture for high-density interconnect PCBs.
Its subsidiary IL JIN Electronics has also acquired a majority stake in Power-One Micro Systems, a solar inverter and EV charger specialist, signalling Amber’s ambition to move beyond air conditioning entirely into India’s broader new energy and mobility electronics ecosystem.
4. Kaynes Technology
Kaynes has posted one of the more startling growth trajectories in Indian electronics manufacturing — revenue climbing sevenfold from ₹3.7 billion in FY20 to ₹27 billion in FY25, a 49 percent CAGR, with EBITDA growing even faster at 58 percent annually. The company operates as a full-spectrum electronics system design and manufacturing provider, spanning PCBA, box build, and ODM work across smart metering and smart lighting.
What sets Kaynes apart from volume-driven peers is its deliberate focus on aerospace, defence, and medical IoT electronics — segments commanding 12-15 percent EBITDA margins versus 4-6 percent for commodity electronics assembly, a margin premium earned through engineering complexity and regulatory compliance that competitors can’t easily replicate.
5. Syrma SGS Technology
Syrma SGS has built its identity around diversification rather than scale — RFID solutions, precision electronics, and PCBA work spanning defence, industrial, and automotive applications, rather than chasing the high-volume consumer categories Dixon dominates. Its joint ventures with Elemaster for high-reliability industrial and railway electronics, and with Shinhyup PCB for multilayer and flexible circuit board manufacturing, reflect a strategy built on partnership-driven capability expansion.
Analysts have increasingly flagged Syrma as a top pick precisely because of that diversified end-market presence — when one sector slows, whether automotive or industrial demand, its exposure to defence and railway electronics provides a cushion that single-category competitors lack.
6. Tata Electronics
Tata Electronics occupies a genuinely unique position spanning both semiconductor fabrication and iPhone assembly simultaneously, running manufacturing operations in Karnataka alongside its flagship Dholera semiconductor fab under construction in Gujarat. Its iPhone assembly work, alongside Foxconn’s, now contributes meaningfully to India’s growing share of global iPhone production.
That dual bet — chips at one end of the supply chain, finished device assembly at the other — positions Tata Electronics as arguably the most structurally important company in India’s electronics ambitions, straddling both the upstream and downstream halves of the manufacturing value chain most competitors only touch at one end.
7. Elin Electronics
Elin holds a specific historical distinction — it was India’s first inverter manufacturer, founded in New Delhi in 1979, and has since built out modern manufacturing units in Noida, Dehradun, and Roorkee producing UPS systems, voltage stabilisers, and solar products, backed by investments exceeding ₹250 crore.
That decades-long specialisation in power electronics gives Elin a technical depth in a category — backup power and energy management — that newer entrants chasing smartphone or TV assembly haven’t had reason to develop, making it the default reference point whenever power backup manufacturing specifically comes up.
8. Avalon Technologies
Avalon has built a growing reputation specifically around export-grade aerospace and rail manufacturing expertise, spanning the full industrial chain from design through assembly, testing, packaging, and shipment. That end-to-end capability distinguishes it from pure assembly-only EMS players focused solely on high-volume consumer categories.
As a publicly listed mid-size manufacturer, Avalon represents the maturing tier of India’s electronics ecosystem — companies gaining genuine global competitiveness in specialised categories like aerospace components and wearables without needing Dixon or Foxconn’s sheer scale to remain relevant.
9. PG Electroplast
PG Electroplast has been steadily transforming from a straightforward contract manufacturer into a more integrated player across India’s consumer durables landscape, with capacity expansions spanning coolers in Rajasthan, washing machines in Greater Noida, refrigerators in South India, and room air conditioners in the West. Its upcoming AC compressor facility marks a deliberate push toward end-to-end control over a component category most competitors still import.
That backward integration strategy mirrors what Dixon and Amber are doing at larger scale, suggesting a broader industry pattern — Indian EMS players increasingly refusing to stay pure assemblers and instead pushing to own more of the value chain themselves.
10. Epack Durable
Epack Durable, listed in 2019, made a deliberate transition from contract manufacturer to Original Design Manufacturer specifically for room air conditioners and small appliances, and now holds roughly 24 percent domestic market share as the second-largest RAC ODM in India. Its financial trajectory has been striking — revenue growing at 23 percent CAGR alongside profit surging at a 96 percent CAGR over five years.
That leap from assembly-for-hire to genuine product design ownership matters enormously — an ODM controls more of the engineering and margin than a pure contract assembler ever can, and Epack’s shift illustrates exactly the kind of upward mobility India’s broader EMS sector is chasing collectively.
Frequently Asked Questions
Q1. Which company is India’s largest electronics manufacturing services provider?
A: Dixon Technologies holds the position of India’s largest EMS company, with sales reaching ₹38,880 crore in FY2024-25, a 119 percent jump from the previous year, driven by capacity expansion across smartphones, televisions, washing machines, and lighting products. It remains net debt-free despite its rapid scale-up, funding growth primarily through internal accruals rather than heavy borrowing.
Q2. What is the difference between an EMS company and an ODM in Indian electronics manufacturing?
A: An EMS (Electronics Manufacturing Services) company like Dixon or Foxconn typically assembles products designed by other brands under contract, while an ODM (Original Design Manufacturer) like Epack Durable takes on genuine product design ownership alongside manufacturing, capturing more engineering value and margin. Several major Indian players, including Dixon and Kaynes, are actively transitioning from pure EMS work toward ODM and even component-level manufacturing to capture higher margins.
Q3. Why are Indian EMS companies moving into PCB and component manufacturing instead of just assembly?
A: India still imports nearly 90 percent of its printed circuit board demand and over 90 percent of components like multilayer ceramic capacitors and resistors, exposing EMS firms to tariff swings and supply chain disruptions from countries like China and Taiwan. Companies including Amber Enterprises, Dixon, Kaynes, and Syrma SGS are investing roughly ₹9,000 crore collectively between FY25-28 specifically to localise this component manufacturing, backed by the government’s Electronics Components Manufacturing Scheme.
Q4. How significant is Apple’s manufacturing shift to India for the broader electronics ecosystem?
A: Apple’s decision to manufacture iPhones in India through Foxconn and Tata Electronics is projected to generate roughly $30 billion in annual electronics exports by FY30, with India’s share of global iPhone production rising from 15 percent currently toward a targeted 25 percent by FY28. Each percentage point of that manufacturing shift creates an estimated $800-900 million in downstream EMS supply chain revenue, directly benefiting component and assembly suppliers like Dixon, Kaynes, and Syrma who feed into that ecosystem.
Q5. What government incentives are driving growth in India’s electronics manufacturing sector?
A: The Production Linked Incentive scheme allocates roughly ₹41,000 crore with production-linked subsidies, while the newer Electronics Components Manufacturing Scheme specifically targets backward integration into PCBs and other high-value components, with disbursements expected to cover 60-65 percent of project costs in some categories. Together these schemes have helped push India’s EMS sector output from ₹8.4 lakh crore in FY2023 toward a projected ₹27.7 lakh crore by FY2028, a roughly 27 percent CAGR.
