What are the Technical Capabilities of the Manufacturer of HDI PCB in China?

When you work with the manufacturer of HDI PCB in China, such as BEST Technology, you are essentially partnering with a factory built around high-density, high-precision interconnect technology—not just standard multilayer boards. Our capabilities cover the full chain from via structure design to complex stack-ups, materials, and final finishing.

Below is a consolidated view of our main technical strengths, based on real HDI manufacturing capabilities at BEST Technology.

1. Full Range of HDI Via Structures

We design and manufacture all the core via types used in HDI PCB:

• Blind vias – connecting outer layers to one or more inner layers without passing through the whole board.
• Buried vias – connecting only internal layers, invisible from outside.
• Through-hole vias – standard plated through holes for robust interconnection and mechanical support.

For HDI, we distinguish clearly between:

Laser microvias (HDI vias)

• Laser-drilled diameter down to 0.07mm (70µm) for prototypes.
• Standard production microvia diameter around 0.10mm.
• Dielectric-to-hole aspect ratio controlled at about 1:1 to maintain plating stability.
• Use of RCC or laser-drillable prepregs for consistent microvia quality.

Mechanical blind/buried vias

• Hole diameters typically ≥0.20mm.
• A cost-effective choice when extreme density is not required.

2. Advanced Laser Drilling and Microvia Technology

We use advanced UV and CO₂ laser systems optimized for different copper thicknesses and dielectric stacks.

Key capabilities include:

Microvia diameter capability

• As small as 0.07mm for prototype builds
• Stable 0.10mm in mass production

Aspect ratio control

• Laser drill depth-to-diameter managed around 1:1, avoiding voids and improving plating uniformity

Material-specific drilling recipes

• Detailed drilling parameters defined according to copper weight and PP thickness
• With PP ≤70µm, we can directly drill very small microvias with excellent wall quality and adhesion

3. High-Layer-Count and Sequential Lamination Capability

To support complex HDI designs, we routinely perform multi-stage lamination with tight dimensional control.

Typical HDI structures we support

• 1+N+1
• 2+N+2 (stacked or staggered microvias)
• 3+N+3 and any-layer HDI

Layer count capability

• Up to 50 layers in standard production
• Up to 100 layers in advanced prototype builds (after technical review)

These capabilities enable routing for dense BGAs, FPGAs, ASICs, and high-speed differential pairs in compact layouts.

4. Fine Line / Space and Registration Accuracy

High-density interconnect designs require fine traces and accurate registration.

Line / space capability

• Inner layers: 2.5 / 2.5 mil
• Outer layers: 3 / 3 mil (finer options depending on copper weight)

Registration accuracy

• Maintained within ≤0.13mm layer-to-layer

This stability is essential for stacked microvias, via-in-pad designs, and fine-pitch BGA breakout (≤0.3mm pitch).

5. Comprehensive Material Expertise

We work with a wide variety of materials to support performance, thermal stability, and reliability:

Standard & High-Tg FR-4

• From standard Tg to ~180°C High-Tg
• High-CTI insulation options

High-speed / low-loss laminates

• Rogers
• Isola
• Taconic
• Arlon
  (Suitable for RF, 5G, high-speed digital, impedance-controlled systems)

Thin-core HDI capability

• Minimum inner core thickness 0.05mm
• Enables compact, multi-stack HDI structures

This material flexibility allows us to optimize stack-ups for signal integrity, thermal performance, and cost.

6. Surface Finishes Optimized for HDI and Fine Pitch

We offer a full portfolio of finishes for fine-pitch and wire-bonding applications:

• ENIG
• ENEPIG
• Immersion Silver
• OSP
• Hard/soft gold plating

These finishes allow us to support:

• BGA pads as small as 8 mil
• Strong solderability and reliable wire-bonding performance

7. Board and Copper Thickness Range

We support a wide range of board constructions, from ultra-thin modules to power-dense designs.

Board thickness range

• As thin as 0.15mm
• Up to 10mm for heavy or high-power boards

Copper thickness range

• From ½ oz for fine-line HDI inner layers
• Up to 20 oz (inner layers) and 28 oz (outer layers) in special prototype builds

This allows us to support logic-dense HDI circuits and high-current power systems within the same manufacturing framework.

8. Robust Process Control and High Reliability

Our HDI capability is reinforced by strict process controls:

• Microvia plating:
  • Copper thickness inside microvias controlled at ≥15µm for thermal-cycle reliability
• In-process inspection:
  • Multiple AOI steps
  • X-ray for internal registration and BGA solder inspection
  • Impedance verification for high-speed designs
• 100% Electrical Testing:
  • Flying Probe or fixture testing ensures no opens or shorts in the full HDI network

In brief, as the manufacturer of HDI PCB in China, we combine:

• Precision laser microvia drilling
• Multi-stage HDI stack-ups
• Fine line/space and registration control
• High-layer-count fabrication
• Material and surface finish expertise
• Wide board and copper thickness options
• And rigorous quality and reliability control

These strengths allow us to deliver HDI PCBs that are smaller, denser, and more powerful than conventional multilayer boards—giving your next-generation electronic products a strong technical foundation.
