18 SMT lines
Operating 18 SMT lines with 01005-capable precision placement and nitrogen-reflow soldering, this facility serves automotive, medical, and aerospace sectors while addressing yield, lead time, and cost priorities. The nitrogen atmosphere delivers void-free joints surviving 150°C engine conditions with PPM-level defects. Medical assembly ensures six-sigma Cpk≥2.0 and full traceability per FDA/ISO 13485. Aerospace applications maintain solder porosity below 1% under thermal shock, with parallel 18-line setup enabling 30% faster turnarounds. This combination consistently reduces per-unit cost by 15-22% while ensuring mission-critical reliability worldwide.
13 DIP lines
Operating 13 DIP assembly lines, precision fluxing, wave soldering, and AOI at every process stage, this facility delivers robust through-hole soldering solutions for automotive, industrial, medical,new energy. The closed-loop AOI feedback system catches insertion defects and solder bridging in real time, ensuring first-pass yields above 99.5%. Wave soldering with optimized flux application eliminates cold joints and voids on heavy copper boards. The 13-line parallel configuration enables rapid order turnarounds and scalable batch production, reducing per-unit labor costs while maintaining consistent quality across high-reliability applications worldwide.
Components warehouse
Constant temp/humidity storage,anti-static,traceability,FIFO control.Operating a components warehouse with constant temperature/humidity control, anti-static protection, full traceability, and FIFO inventory management, this facility ensures optimal material integrity for moisture-sensitive and ESD-vulnerable electronic components. The climate-controlled environment prevents oxidation and solderability degradation, extending component shelf life by over 300%. Real-time barcode tracking with FIFO discipline eliminates expired material usage and reduces obsolescence write-offs by 25%. The anti-static flooring and packaging safeguard sensitive devices against latent ESD damage, while full lot traceability supports rapid recall and root-cause analysis for automotive and medical compliance requirements worldwide.
PCBA First Piece Tester
Utilizing a PCBA first-piece tester, this facility verifies component placement, polarity orientation, soldering quality, and basic electrical functionality before mass production release. The automated inspection system compares the initial assembled board against CAD data and BOM specifications, instantly flagging misloaded parts, reversed diodes, and insufficient solder fillets. This upstream quality gate captures defects at the source, preventing costly rework and scrap across full production runs. By validating first-article correctness within minutes, the tester slashes setup verification time by 70%, reduces line downtime, and ensures zero-defect launch for subsequent volume production - a critical safeguard for automotive and medical programs where non-conformance costs are exceptionally high.
DIP Automated Optical Inspection
Deploying DIP automated optical inspection systems before and after wave soldering, this facility verifies through-hole component presence, polarity, solder joint integrity, bridging, and voiding with high-speed precision. The dual-stage AOI configuration captures pre-solder insertion errors and post-solder defects simultaneously, enabling immediate correction before defects propagate downstream. Automated algorithm detection identifies insufficient fill, skewed leads, and excess solder that compromise mechanical strength. This closed-loop inspection approach reduces manual visual inspection dependency by 85%, cuts rework labor costs significantly, and ensures consistent through-hole soldering quality for industrial controls, power supplies, and automotive modules where connection reliability is paramount.
Professionals Engineering Department
Supported by an engineering team of over 50 professionals, this facility delivers comprehensive technical expertise spanning component selection, SMT process optimization, electrical fault diagnosis, soldering quality assurance, and ICT/FCT/AOI testing. The cross-functional group proactively identifies root causes of yield loss, signal integrity issues, and test coverage gaps, implementing corrective actions before production ramps. By embedding design-for-manufacturing principles into process development, the engineering team accelerates time-to-market by 40%, drives continuous cycle time reduction, and sustains first-pass yields above 99% for complex automotive, medical, and industrial electronics where technical rigor and reliability are non-negotiable.
8 function testing and programming lines
Operating 8 dedicated functional testing and firmware programming lines, this facility validates PCBA performance, signal integrity, power distribution, and microcontroller operation before product shipment. The functional test stations simulate real-world operating conditions to verify voltage rails, communication interfaces, and sensor responses, while the programming lines securely flash application firmware into onboard microchips. This integrated test-and-program approach captures both hardware and software defects at the final assembly stage, eliminating field failures caused by unprogrammed devices or marginal electrical performance. The 8-line parallel configuration supports high-volume throughput with 100% electrical screening, significantly reducing customer returns and warranty claims for demanding automotive and medical applications.
6 Conformal Coating Lines
this facility applies protective polymer layers that shield PCBA from moisture, dust, chemicals, and thermal extremes. The precision process prevents corrosion and electrical shorts, significantly extending product lifespan in harsh environments. This capability ensures long-term reliability for automotive under-hood systems, outdoor industrial controls, and aerospace electronics where environmental exposure is unavoidable.
3D X-Ray Machines
Employing advanced 3D X-ray inspection systems, this facility non-destructively examines solder joints, BGA voids, and internal PCB structures to ensure uncompromised PCBA quality. The three-dimensional imaging capability reveals hidden defects such as head-in-pillow, insufficient wetting, and micro-cracks that 2D AOI cannot detect. Automated void calculation quantifies BGA void ratios against IPC Class 2/3 standards, enabling real-time process correction. This non-invasive inspection method eliminates destructive cross-sectioning, reduces inspection cycle time by 40%, and ensures reliable performance for automotive, aerospace, and medical electronics where latent defects are mission-critical.
