Schematic capture, multilayer layout, signal integrity, and DFM under one accountable team. Designs that route on the first spin and assemble cleanly on our SMT lines.
Design → DFM → SMT → Inspection → Testing → Delivery. Each transition is documented, inspected, and signed off — so the board you ordered is the board that ships.
Schematic + multilayer layout against your spec, with stackup and impedance targets locked.
10-point pre-tapeout review against our fab's actual capability file. Iteration loop here saves a spin.
Lines 1–4 at Madurai, fine-pitch BGA and 0201 placement at 80k CPH with paste verification.
100% AOI on top and bottom, X-ray on BGA voids, plus IPC-A-610 visual sign-off.
ICT for high-volume, flying probe for low-volume, plus functional test against your firmware.
ESD-safe packaging, MBB + desiccant for export, full traceability pack with every shipment.
Each capability is a discipline our design team runs to its own checklist — with specific limits and tolerances you can hand to your customer's audit team.
From 2-layer single-sided boards to 16-layer high-density stackups with controlled impedance — sized to your escape routing, signal speed, and cost targets.
DDR4/5, PCIe Gen4/5, USB 3.x SS and Ethernet routed against measured impedance targets with controlled differential pairs and disciplined return paths.
RF microstrip / stripline for sub-6 GHz and mmWave; tight power layout for DC-DC converters and IGBT/MOSFET stages with snubber and gate-drive isolation.
Stackup-aware impedance design with per-panel test coupons. Documented impedance reports ship with every prototype lot.
Plane decoupling, return-path discipline, and ground-stitching strategy refined for pre-compliance success. Saves the second trip to the EMC chamber.
Every design passes our 10-point DFM review before tapeout: annular ring, courtyard, panelisation, fiducials, testpoint coverage, mask slivers, plane splits.
These thresholds describe the design window we'll quote against without question. Tighter targets are possible — ask, and we'll let you know what changes.

We accept native project files from the major EDA suites and sign-off simulators — no format-conversion gymnastics, no "please re-export as Gerber."
Selected articles from the PCB Design & Engineering corpus — DFM, impedance, signal integrity, and the calls we make before tapeout.
What hardware teams ask before handing us a schematic — answered against our real layout capability.
From 2-layer single-sided boards to 16-layer high-density stackups with controlled impedance, on FR-4 Tg 150–170 or polyimide for rigid-flex — sized to your escape routing, signal speed, and cost target.
Yes. We route DDR4/5, PCIe Gen4/5, USB 3.x SuperSpeed, and Ethernet against measured impedance targets (85/90/100 Ω differential) with continuous reference planes, validated up to 16 GT/s.
Altium Designer, Cadence Allegro, KiCad, and Mentor Xpedition, with HyperLynx and Ansys SIwave for SI/PI. We accept native project files or a full Gerber/ODB++ package.
Layout runs 5–10 working days and a built prototype 7–14 days, depending on layer count and complexity. Every design clears a 10-point DFM gate before tapeout to avoid a re-spin.
Yes. Stackups are designed impedance-aware with per-panel test coupons, and a documented impedance report ships with every prototype lot — single-ended 50 Ω and differential 85/90/100 Ω to ±7–10%.
Yes — design, SMT assembly, and test are all in-house, so a board moves from layout to our Madurai line without handing off to a separate fab, and the DFM review is written against the line that will actually build it.
Send what you have — schematic, BOM, mechanical drawing, or just a target spec — and we'll come back within two working days with a manufacturability review and a quote.
