Room-AC contract manufacturer turning into an electronics group: IL JIN (EMS) and Ascent Circuits (PCBs), now building multi-layer and HDI board plants
Price
₹5,865
snapshot 30 Oct 2026
Strengths
Ascent Circuits got a ₹991 Cr multi-layer PCB approval (Oct 2025) for Hosur, with trial production guided for Q2 FY27 (Jul-Sep 2026)
Ascent-K Circuit (JV with Korea Circuit) got ECMS approval for a ₹3,200 Cr HDI/flex PCB plant near Jewar (Jan 2026); groundbreaking Jun 2026
Cooperation pact with Germany's Schweizer Electronic (Jun 2026) for auto/industrial boards
Risks
Earnings still dominated by seasonal room-AC business; FY26 profit fell to ₹226 Cr
₹4,200 Cr of PCB capex before meaningful PCB revenue

Where it fits
An SMT line prints solder paste onto a bare board, robots place hundreds of components per board, and a reflow oven melts the solder. Contract manufacturers (EMS) run these lines for phone, laptop, meter, car and defence brands, then box-build the finished product.
Why it matters
Assembly made India the world's No. 2 phone maker, but it adds only ~18-20% of value (GTRI estimate) because the board, modules and parts are imported. ECMS lets the same EMS companies capture the parts - Kaynes, Amber, Syrma and Dixon are among its largest applicants.
Where the value pool sits
Large but thin: phone assembly earns low-single-digit net margins (Dixon ~3.4% in FY26) while high-mix industrial EMS earns more (Kaynes ~10%). Moving into PCBs and modules lifts margins and makes customers stickier. Mobile phone production alone was ~₹6.27L Cr in FY26 (MeitY data via govt release, Aug 2026).
Key drivers
Phone and laptop PLI volumes and exports
Backward integration into ECMS-backed PCBs and modules
Industrial, auto, meter and defence electronics growth (higher margin than phones)
Potential bottlenecks
Imported boards and modules set the cost floor; local value addition is still ~18-20%
Working capital and customer concentration (a few phone brands dominate)
Skilled SMT engineers and yield know-how
Investor metrics to watch
Revenue mix: mobile vs industrial/auto/defence
EBITDA margin trend as component plants start up
Share of in-house PCBs/modules in the bill of materials
