HDI PCB: What You Need to Know Before Sourcing from China


High-Density Interconnect (HDI) PCBs are essential components in modern electronics, offering superior performance and compact designs. As demand grows, many buyers turn to China for cost-effective solutions. This guide covers everything you need to know about HDI PCB, from types to sourcing strategies.


How to Find Reliable HDI PCB from China in 2025


Sourcing HDI PCB from China requires careful vetting. Look for suppliers with certifications like ISO 9001 and UL listings. Platforms like Alibaba and Global Sources can help identify reputable manufacturers. Always request samples and check customer reviews before placing bulk orders.


What Buyers Should Know Before Buying HDI PCB from China


Understand lead times, minimum order quantities (MOQs), and payment terms. Chinese suppliers often offer competitive pricing but may have longer production cycles. Ensure clear communication about specifications and quality standards to avoid misunderstandings.


Types of HDI PCB


1. 1+N+1: Single-layer HDI with microvias.
2. 2+N+2: Double-layer HDI for higher density.
3. Any-layer HDI: Most advanced, allowing vias anywhere on the board.


Functions and Features of HDI PCB


HDI PCB enable smaller, faster, and more efficient devices. Key features include:
- High signal integrity
- Reduced size and weight
- Enhanced thermal performance


Scenarios of HDI PCB


Common applications include smartphones, medical devices, and automotive electronics. For example, a leading smartphone brand reduced device thickness by 20% using HDI PCB technology.


How to Choose HDI PCB


Consider:
- Layer count and via type
- Material quality (e.g., FR4 or high-frequency laminates)
- Supplier's technical support and prototyping capabilities


HDI PCB Q & A


Q: What's the typical lead time for HDI PCB orders?
A: 2-4 weeks for standard orders, longer for complex designs.


Q: How do I verify a Chinese supplier's quality?
A: Request third-party test reports and visit factories if possible.


Q: Can HDI PCBs be repaired?
A: Limited repairability due to dense layouts. Prevention is key.


Q: What's the price range for HDI PCBs?
A: $0.50-$5 per unit depending on complexity and order volume.


Q: Are there alternatives to HDI PCBs?
A: Standard PCBs work for less demanding applications but lack HDI advantages.
