Automotive Electronic Components & PCBA / EMS Sourcing in China
End-to-end China sourcing management for automotive-grade PCBA assembly and EMS contract manufacturing — from supplier screening and prototypes to series delivery, owned by ZRG.
Automotive electronics and PCBA/EMS is one of the categories where ZRG holds the highest degree of supply-chain control. We work with audited SMT and box-build capacity in the Yangtze and Pearl River Delta, covering engineering samples, pilot runs and volumes into the millions of units per year.
For overseas OEMs and Tier-1s the difficulty is rarely finding a factory — it is engineering communication, quality-system consistency and batch-to-batch stability. ZRG's Chinese engineering team works directly on the line and reports in European documentation standards, removing the delays caused by time zones and language.
Scope of service
PCBA assembly & test
SMT, wave soldering, conformal coating, ICT/FCT functional and burn-in testing with automotive component traceability.
EMS box build
Turnkey manufacturing from PCBA to full box build, enclosure assembly, packaging and outgoing inspection.
Components & semiconductors
Compliant sourcing of automotive MCUs, power devices, passives and connectors, including alternative-part evaluation.
Prototyping & low volume
Engineering samples, B/C samples and pilot runs to validate design for manufacturability (DFM) quickly.
Quality documentation
PPAP, control plans, FMEA, MSA and batch traceability issued in the customer's own templates.
Logistics & delivery

Frequently asked questions
What is the minimum order quantity?
PCBA prototypes start at 10 pieces. Series MOQ is typically 500–2,000 pieces depending on component packaging and test-fixture investment.
How is our IP and design data protected?
An NDA is signed before kickoff, Gerber and BOM data is shared strictly on a need-to-know basis, and the package can be split across suppliers so no single party holds the complete design.
Which Incoterms do you support?
EXW, FOB and DAP/DDP are all common. European customers usually work with FOB Shanghai/Shenzhen or DAP to the destination warehouse.
