Growth Market Opportunities: The PCB market is expanding steadily, with AI driving explosive demand for optical modules and server PCBs; Light Counting forecasts high-speed optical module sales to reach $6.7 billion by 2029. The company's IC substrate business reported revenue of 76.1405 million yuan in 2025, showing strong growth and promising future profitability.

2. Risks and Opportunity Insights: Capacity bottlenecks are prominent, with a utilization rate of 88.57% in 2025; IPO fundraising aims to alleviate this and accelerate new business. Positive factors include technical advantages like controlling impedance tolerance within ±6% for optical modules. Potential negatives include intensified competition. Key takeaways include its early focus on HDI and IC substrates to capitalize on import substitution opportunities.

3. Collaboration and Model Insights: Supply chain partnerships include Intel and Maxscend. The latest business model focuses on AI infrastructure, with three key business directions (IC substrates, optical module PCBs, AI server PCBs) offering collaboration avenues. While direct support policies aren't mentioned, IPO funding supports expansion.

Hongban Technology's production techniques and commercial opportunities offer valuable lessons for factories.

1. Product Manufacturing Requirements: Advanced HDI board manufacturing demands high precision, such as a minimum blind via diameter of 50 microns and a core board plating thickness of 0.05 mm. IC substrate production requires mastery of Tenting and mSAP processes, presenting high technical barriers and scarce mass-production capabilities.

2. Commercial Opportunities: Significant potential exists for IC substrate import substitution; the company has already entered the RF chip supply chain. Flexible and rigid-flex boards show stable growth, with the latter achieving a 40% gross margin, becoming a profit engine. AI is driving PCB demand, particularly in the fast-growing optical module and server board markets.

3. Digitalization and E-commerce Insights: The technology upgrade path is clear, transitioning from low-end boards to HDI and then expanding into AI. Digitalization efforts are evident in capacity management and operational optimization via IPO financing. E-commerce insights are limited, but fundraising for expansion strengthens scaled production capabilities.

Hongban Technology highlights key industry trends and new technology solutions.

1. Industry Development Trends: The global PCB market is growing steadily with a 5.20% CAGR. The AI computing boom is driving demand for optical module and server PCBs; high-speed optical module sales are expected to double in the next five years. The company ranks 35th in China's PCB Top 100 and 58th globally.

2. New Technology Breakthroughs: Leading HDI technology includes 26-layer any-layer interconnect boards. Optical module PCB capability reaches 1.6TB, with impedance tolerance controlled within ±6%, outperforming the industry standard of ±10%. AI server PCB R&D involves 24-layer board technology, with patents pending. IC substrate process breakthroughs support 10-micron samples.

3. Customer Pain Points & Solutions: A key pain point is capacity bottleneck (88.57% utilization in 2025); the solution involves IPO-funded construction of a new 1.2 million sqm HDI project. Technical expertise is being converted into orders, such as optical module mass-production capability alleviating customer supply shortages.

Hongban Technology indicates significant platform needs and offers insights for investment attraction and management.

1. Business Demand for Platforms: There is high demand for PCB supply; the company provides mainboards for smartphone brands and chip manufacturers (e.g., Maxscend). Platforms need to address capacity issues, as advanced HDI bottlenecks impact supply chain stability.

2. Latest Platform Practices & Investment Attraction: Post-IPO, the company leverages financing platforms for capacity expansion; new projects will strengthen its consumer electronics and AI businesses. Abundant investment opportunities exist, as the company, being a leading supplier (e.g., in optical module PCBs), can be integrated into platform cooperation systems, attracting AI-related enterprises.

3. Operational Management & Risk Mitigation: The high capacity utilization rate of 88.57% highlights the management insight that fundraising optimizes production. Risk mitigation requires attention to technical risks, such as IC substrate yield control. Platform operations should support import substitution to avoid over-reliance on foreign-dominated markets.
