HDI PCB Core Advantages

1.Ultimate integration capability: significantly increases component layout density, reduces the finished PCB size, perfectly adapts to the miniaturization and thinning design requirements of smart terminals, and supports ultra-complex wiring design of up to 64 layers and 150,000+ pins

2.Excellent signal performance: effectively shortens the signal transmission path, reduces transmission loss and crosstalk, significantly improves the signal integrity of high-speed digital circuits, and adapts to high-frequency, high-speed and miniaturized SIP packaging design scenarios

3.Full-process technical empowerment: our in-house professional engineering team provides one-on-one design support, completes more than 150 free DFM/DFA manufacturability checks, avoids design risks in advance, optimizes mass production yield and cost, and and provides professional DFM review to optimize production efficiency and reliability

4.Flexible mass production adaptation: seamlessly accepts all types of orders from R&D prototypes, small-to-medium batch trial production to scaled mass production. Our production bases in China ensure delivery flexibility, and we apply the same quality control and service priority to both small-batch and large-volume orders

5.One-stop supporting services: synchronously supports full-chain services including component procurement, SMT/DIP assembly, X-ray/BGA inspection, functional testing and finished product shipping, realizing one-stop delivery from design to finished product, supporting both full Turnkey managed mode and customer consigned assembly mode


HDI PCB Quality Control

All products undergo strict full-process inspection before delivery, including 100% automated optical inspection (AOI), 3D solder paste inspection (SPI), X-ray inspection, flying probe test, fixture test, impedance analysis, continuity and open circuit verification, microsection analysis, and high-voltage insulation test. This ensures that every product meets IPC Class 2/3 standards, with a stable yield rate of over 99.8%.


HDI PCB Application

5G/6G communication terminals, wearable smart devices, IoT smart terminals, medical precision diagnostic equipment, automotive ADAS systems, industrial automation control modules, laptops, tablets, high-end consumer electronics and other highly integrated electronic devices.
