Built in Shenzhen. Deployed Worldwide.

> 20 years in the Longhua/Bao'an industrial cluster. The world's most concentrated electronics supply chain.

01 Our Story

EMS-INDUSTRIAL was founded in 2005 in the heart of Shenzhen's manufacturing district. What began as a small SMT job shop has grown into a full-spectrum industrial electronics manufacturer serving customers across 30+ countries.

Our location in the Longhua/Bao'an corridor gives us direct access to the world's densest concentration of PCB fabricators, component distributors, and specialty material suppliers — a supply-chain advantage that translates directly into faster turnarounds and better pricing for our customers.

We specialize exclusively in industrial-grade electronics — products that must operate 24/7/365 in environments where failure is measured in production-line downtime, not warranty claims. This focus shapes every decision we make, from component selection to final test protocol.

03 Technical Capabilities

Deep expertise in the processes that matter for industrial electronics. We invest where it counts.

[THICK-COPPER PCB]

Up to 4oz (140μm) copper on outer layers, 3oz on inner layers. Heavy copper plating process with controlled impedance. Used extensively in motor drives, power supplies, and welding equipment where trace current capacity must exceed 30A continuous.

[MIXED SMT + THT]

Full mixed-technology capability. SMT components down to 0201 alongside through-hole connectors, transformers, relays, and large electrolytic capacitors. Selective wave solder with pallet fixturing for boards with bottom-side SMT components.

[BGA & QFN ASSEMBLY]

0.4mm pitch BGA placement, 100% X-ray inspection (2D + CT). Void analysis per IPC-7095 Class 3 criteria. QFN sidewall solder inspection via angled endoscopic camera. Rework capability with precise BGA reball stations.

[CONFORMAL COATING INLINE]

Automated 3-axis selective coating robot with needle and spray valve heads. Three chemistries (acrylic, silicone, parylene). UV-cure and thermal-cure options. 100% automated optical inspection of coating coverage and thickness.

[POTTING & ENCAPSULATION]

Vacuum potting chambers for bubble-free encapsulation. Custom CNC-machined mold tooling. Epoxy, polyurethane, and silicone compounds. Post-cure thermal cycling for stress relief. IP65/IP67/IP68 rated solutions.

[BOX BUILD & INTEGRATION]

Complete turnkey: PCB assembly to enclosure, wiring harness fabrication (UL 758), functional test with automated test equipment, custom labeling and serialization, and export packaging. DIN-rail, panel-mount, and wall-mount configurations.
