ONE-STOP MANUFACTURING
One Factory, the Complete Electronics Manufacturing Chain
UDD integrates five core services — mold making, injection molding, spray coating, SMT welding and assembly & packaging — on a single campus, backed by shared ERP/MES digital control and reliability testing, serving customers from development sampling to volume production and shipment.
Five Core Services
Mold Making
Precision mold design and fabrication to 0.02mm on MAKINO CNC machining centers, from single-cavity prototypes to high-cavitation production tooling.
Learn More
Precision Injection
Precision injection molding with Japanese all-electric and Haitian machines, delivering consistent housings and structural parts for smart terminals.
Learn More
Spray Coating
Three-coat UV spray line handling parts up to 400cm with stable color matching and a high-gloss, durable surface finish.
Learn More
SMT Welding
Siemens dual-rail SMT lines mastering 01005, POP and 0.25mm-pitch BGA, producing more than 10M SMT pieces per year.
Learn More
Assembly & Packaging
60m assembly main line producing 5M finished units per year, with IPX7-5m waterproof assembly and full MES traceability.
Learn MoreQuality Management
Full-Process Quality Control
IQC, IPQC, FQC (final inspection) and OQC gates run through the entire process, with first-article confirmation and in-process patrols securing consistent mass production.
Digital Traceability
ERP/MES systems run through production with queryable batch data, enabling rapid issue location and closed-loop improvement.
Precision Dimensional Inspection
CMM and vision measurement cover mold parts, cores & cavities and molded products, with full inspection of critical dimensions.
Environmental Reliability Testing
Low-temperature aging, high-temperature/humidity and thermal shock simulations verify long-term stability under harsh conditions.
SPI/AOI Inline Inspection
Solder paste inspection and AOI form a dual defense against placement defects; X-Ray examines hidden BGA and POP solder joints.
Final Test & Reliability
PCBA functional and RF tests cover electrical performance; final aging, IP water-proof and temperature cycling verify long-term quality.
