Frequently Asked Questions
Why is IC substrate manufacturing strategically important for China?
IC substrates are essential for advanced semiconductor packaging including flip-chip BGA and 2.5D/3D packaging. China's IC substrate self-sufficiency is estimated at only 10-15%, creating a critical bottleneck for domestic chip packaging. Shennan Circuits is leading efforts to build domestic IC substrate capacity, but the technology gap with Ibiden and Shinko Electric in fine-pitch packaging substrates remains 2-3 generations.
How is the transition to HDI PCBs progressing in China?
Chinese PCB manufacturers have rapidly adopted HDI technology for smartphone, laptop and wearable applications. KB Hitech, Shennan and several others produce 6-10 layer HDI boards with any-layer interconnect capabilities. The transition to mSAP (modified semi-additive process) for finer line/space below 30/30 microns is ongoing, with leading Chinese PCB fabs achieving 20/20 micron capabilities comparable to Japanese and Taiwanese manufacturers.
What environmental challenges does China's PCB industry face?
PCB manufacturing involves hazardous chemicals including etchants, electroplating solutions and solvents that require strict wastewater treatment. China's environmental regulations have tightened significantly, forcing small PCB shops to close and driving consolidation. Major manufacturers invest 50-100 million RMB annually in wastewater treatment systems. The shift to lead-free and halogen-free PCB materials adds further manufacturing complexity and cost.
How is 5G driving demand for specialized PCBs in China?
5G base stations require high-frequency PCBs made from low-loss materials like RO4000, Megtron and TU-862 to minimize signal attenuation at mmWave frequencies. Each 5G macro base station uses 3-5x more PCB area than 4G equivalents. WUS Printed Circuit and Shennan Circuits are major beneficiaries of China's 5G infrastructure buildout, producing specialized antenna PCBs and RF circuit boards meeting stringent insertion loss requirements.
What is the status of China's PCB equipment and materials industry?
China imports over 60% of its PCB manufacturing equipment and 70% of high-frequency laminate materials. Major equipment suppliers include Japanese companies (Orbotech for AOI, Schmoll for drilling) and European companies (Schmid for plating). Domestic equipment companies are developing direct imaging, laser drilling and automated handling systems, but adoption rates remain low due to performance and reliability concerns. High-frequency laminates from Rogers and Panasonic are still largely irreplaceable for 5G applications.
