Proven Deliverables

In-Depth Industrial Case Studies

Real-World Field Outcomes
Automotive & EV 16-Week NPI Ramp

Tier-1 EV Powertrain & Battery Management System (BMS) Localization

The Challenge

A major electric two-wheeler OEM relied on East Asian EMS imports for 72V 150Ah smart BMS and vehicle telematics units. Facing 26-week lead times, 18% customs tariff penalties, and erratic firmware updates, they required immediate Indian localization without compromising AEC-Q100 automotive reliability standards.

Zillion GBS Engineering Solution

Orchestrated an end-to-end industrialization cell in Pune: executed full DFM/DFA circuit redesign to accommodate localized passive components; established dedicated SMT line utilizing high-speed Yamaha pick-and-place with Koh Young 3D SPI and 12-zone nitrogen reflow; integrated robotic selective conformal coating (Parylene/Silicone) and automated high-voltage hipot isolation testing.

Quantifiable Results & Metrics:
  • 42% Total Landed Cost Reduction compared to imported CBU modules
  • Supply lead time slashed from 26 weeks down to 6 weeks
  • SMT First-Pass Yield (FPY) sustained at 99.85% across 120,000+ units
  • Zero warranty field failures reported over 18 months of commercial fleet deployment
Medical & Healthcare 7.5 Months to Clinical Trial

Class-II Portable In-Vitro Diagnostics Analyzer: Rapid NPI to Commercial Pilot

The Challenge

A diagnostic MedTech startup needed to transition a lab prototype into a sterile, battery-powered clinical analyzer. The device required an 8-layer rigid-flex PCB, sensitive photodiode optical sensor alignment, a biocompatible ultrasonic-welded housing, and strict ISO 13485:2016 lot-level traceability for CDSCO and FDA 510(k) filings.

Zillion GBS Engineering Solution

Formed a cross-functional squad linking Bengaluru PCB layout experts with our Pune cleanroom moulding partner. Fabricated Class 10,000 cleanroom tooling on Engel 80-ton tie-bar-less injection presses; executed rigid-flex SMT assembly under IPC-A-610 Class 3 conditions; laser-etched 2D DataMatrix serials with component-level lot tracking.

Quantifiable Results & Metrics:
  • Commercial pilot reached in 7.5 months (vs. industry benchmark of 16 months)
  • 100% First-Attempt Pass in IEC 60601-1-2 EMC Class B immunity compliance
  • Tooling dimensional accuracy held within ±0.015 mm tolerance
  • Granted CDSCO Medical Device Manufacturing License MD-9 with zero major audit non-conformances
Industrial & Energy 500,000 Units Delivered

Smart Grid Cellular Gateway Deployment Under BIS IS 16444 Mandate

The Challenge

A national smart metering infrastructure contractor won a 500,000-unit deployment tender. The units operate in harsh outdoor electrical substations with extreme thermal swings (-40°C to +85°C), high electromagnetic surge transients, and mandatory BIS IS 16444 tamper-prevention hardware requirements under tight delivery penalties.

Zillion GBS Engineering Solution

Balanced dual-facility high-volume SMT manufacturing across Pune and Bengaluru using Fuji NXT III lines (180,000 CPH combined). Deployed custom bed-of-nails automated test stations with Rohde & Schwarz CMW500 cellular RF calibration, automated two-part polyurethane potting for IP67 sealing, and 100% 48-hour thermal chamber stress burn-in.

Quantifiable Results & Metrics:
  • Sustained peak volume output of 65,000 units/month across dual plants
  • Process Capability Index Cpk > 1.74 across critical RF power parameters
  • 100% On-Time Delivery milestone adherence across 12 consecutive months
  • 99.91% system availability across 500,000 deployed substation endpoints
Operational Transformation 16-Week Lean Sprint

MSME Electronics Factory Turnaround: Lean TPM, SMED & OEE Optimization

The Challenge

A Pune-based mid-sized EMS provider with 3 SMT lines was struggling with an Overall Equipment Effectiveness (OEE) of only 62%. Frequent product changeovers took 4.2 hours each, component scrap stood at 3.8%, and solder bridging rework caused severe delivery bottlenecks and customer escalations.

Zillion GBS Engineering Solution

Deployed a dedicated 16-week shop-floor transformation squad: implemented Single-Minute Exchange of Die (SMED) cart pre-staging; introduced barcode feeder verification to prevent reel mismatch (Poka-Yoke); calibrated solder paste printer squeegee pressures; and trained 48 floor technicians to IPC-A-610 Class 3 solder inspection standards.

Quantifiable Results & Metrics:
  • SMT line changeover time slashed from 4.2 hours down to 32 minutes
  • Overall Equipment Effectiveness (OEE) climbed from 62% to 84.5%
  • SMT component placement scrap plummeted by 76%
  • Passed Tier-1 European OEM vendor qualification audit with a 94% score
