From single layer to multi-layers, FR-4, FPCB, R&F PCB, AL PCB, CU PCB.

we deliver end-to-end EMS solutions:

• 12 SMT lines for 01005 component assembly

• Box-build integration with IPC-A-610 Class 3 standards

• 40% supply chain cost optimization through vetted AVL partnerships

Our decade-long expertise accelerates 12-week NPI cycles for 200+ OEMs worldwide, achieving 99.2% on-time delivery through AI-driven production scheduling – enabling 30% faster market entry versus traditional EMS models.

Our Fuji NXT lines (52k CPH, ±25μm) handle 0.3mm pitch components with 3D AOI/SPI inspection. Custom J-STD-005 reflow profiles achieve IPC Class 3 compliance (99.98% joint reliability), while vacuum soldering ensures <1% BGA voids per IPC-7095. Mini-wave systems maintain <5ppm defect rates for mixed-technology boards.

Our Vitronics Delta wave systems process 500+ PCBs/hour with dual-phase soldering (2-5s dwell), achieving IPC Class 3 compliance through 45° nozzle optimization and <100ppm O₂ environment. Thermal-compensated conveyors maintain ±2°C stability, enabling 99.9% fill rates verified by automated X-ray inspection (AXI).

Our IPC-certified technicians provide 0402-level rework using JBC stations and Sn96.5Ag3Cu0.5 solder (IPC J-STD-004B). With ESD S20.20 workcells and 3D X-ray validation, we achieve 99.9% success rate for medical/aerospace assemblies, maintaining <10μm placement accuracy.

SunLight PCB offers end-to-end cable and harness manufacturing, from cutting and stripping to crimping, soldering, and inline testing. We construct complex harnesses and wiring systems to your specifications using high-performance cabling, connectors, and other components.

Our PCB coating spray services can help with PCB products that require a high level of humidity resistance. We offer both manual spray coating and automated spray coating for:

• Humidity-resistant PCBs

• Printed circuit boards requiring protection from moisture

• Electronics where condensation could lead to malfunction

At every stage, from prototyping to volume production, SunLight PCB enforces stringent quality control measures compliant with ISO 9001:2015. We apply state-of-the-art testers and inspection equipment to systematically validate soldering quality, PCB functionality, system performance, and reliability to exceed industry standards. All products are subjected to 100% testing and visual inspection before shipment.

With over 30,000 square feet of dedicated manufacturing space in Shenzhen, China, and longstanding supplier partnerships, electronic manufacturers SunLight PCB has the scale, flexibility, and capabilities to produce anything from small test runs to millions of units per year based on your requirements. Leverage our expertise and capacity to gain a competitive edge through high-quality, affordable electronic manufacturing services.

Beyond PCBs and cables, SunLight PCB provides comprehensive system integration, including enclosure design/assembly, analog/digital testing, burn-in, flash programming, and functional testing. Our turnkey solutions cover all aspects of electronic components manufacturing, from bills of materials (BOMs) and assembly procedures to final calibration, quality checks, and order fulfillment.
