Board Thickness Options

Different applications require different board thicknesses. We manufacture across the full range with precision control.

📄

Ultra-Thin (0.2-0.6mm)

For space-constrained applications like wearables, medical implants, and compact IoT devices. Flexible or rigid-flex constructions available.

📋

Standard (0.8-1.6mm)

Most common thickness range for general-purpose electronics. 1.6mm is industry standard for single and double-sided boards, and 4-8 layer multilayers.

📚

Thick (1.8-3.2mm)

For high-layer-count boards (12+ layers), heavy copper designs, and applications requiring mechanical rigidity and thermal capacity.

📖

Extra-Thick (3.2-6.0mm)

Specialty applications: high-power boards, backplanes, industrial control systems, and boards requiring extreme mechanical stability.

Why Thickness Matters

Thickness Selection Considerations

Board thickness affects mechanical, thermal, and electrical performance. Choose the right thickness for your application.

🔧

Mechanical Strength

Thicker boards resist bending and vibration better. Critical for large boards, connector-heavy designs, and harsh environment applications.

🌡️

Thermal Capacity

More copper layers and thicker boards provide better heat spreading. Important for power electronics, LED boards, and high-current designs.

📏

Impedance Control

Layer spacing affects impedance. Thinner boards allow tighter coupling for differential pairs but require careful stack-up design.

📦

Form Factor

Ultra-thin boards enable compact products: smartphones, wearables, medical implants. Trade-off with layer count and copper weight.

🔌

Connector Fit

Standard connectors expect 1.6mm boards. Custom thickness may require connector selection or mounting modifications.

💰

Cost Impact

Non-standard thickness may affect cost and lead time. We optimize stack-up to achieve target thickness with standard materials when possible.

Thickness Control Process

Precision Manufacturing

1

Stack-up Design

Calculate core and prepreg combinations to achieve target thickness while meeting electrical requirements.

2

Material Selection

Select appropriate core thicknesses and prepreg styles. Balance symmetry for warpage prevention.

3

Lamination Control

Precise pressure and temperature control during lamination ensures consistent final thickness.

4

Verification

Thickness measured at multiple points. Report provided with actual measurements across the panel.
