Different Types of Rigid PCB

HXD can supply various rigid PCB types to meet the needs of different electronic applications:

Single-Sided PCB: A Single-Sided PCB has conductive traces on only one side of the substrate. It has a simple structure, and its production process is very mature. Because it uses fewer materials and fewer steps, it usually has the lowest production cost of common PCB types.

Double-Sided PCB:  A Double-Sided PCB has conductive circuits on both sides of the substrate. Electrical connections between the two sides are made through Plated Through Holes (PTH). Compared with a single-sided board, a double-sided PCB offers much higher wiring density. This allows designers to place more components and build more complex circuit layouts.

Multilayer PCB: Multilayer PCBs have three or more conductive layers separated by insulating materials. The layers are connected through vias,  blind vias, and buried vias. These boards are used in high-performance products that need more routing space, better signal control, and stable power delivery.

HXD provides custom multilayer PCB solutions, including 4-layer, 6-layer,  8-layer, and 10-layer PCBs. We can adjust the stackup, materials, copper thickness, vias, and surface finish based on your project requirements.

HXD 12-Layer PCB Stack-up

Stack-up design is critical for reducing EMI and ensuring signal integrity. Our engineering team works closely with you to optimize layer counts and material combinations. We aim to provide the most cost-effective solution for mass production without compromising performance.

HXD Technical Advantages:

  • Precision Impedance Control: Using advanced lamination monitoring and high-precision etching, we control the thickness of Cores and Prepregs at the micron level. This ensures we meet impedance tolerance requirements of ±5% to ±10%.
  • Hybrid Lamination: We specialize in mixing materials like Rogers + FR4. By precisely controlling the Coefficient of Thermal Expansion (CTE) for different materials, we deliver high-frequency performance while significantly reducing your material costs.
  • Complex Interconnect Support: We provide expert stack-up designs for 10-layer and 12-layer HDI boards, fully supporting Blind and Buried Vias.

Quality Assurance

Quality Control and Testing for Rigid PCB

Each rigid PCB order goes through strict process control and inspection, from inner layer checks to final board verification. This helps ensure stable quality and reliable performance.

100% Electrical Testing

100% Electrical Testing

Every board is fully tested for open circuits, short circuits, and net continuity before shipment. We use flying probe or fixture-based testing depending on volume, ensuring zero electrical defects reach your assembly line.

100% Automated Optical Inspection

100% Automated Optical Inspection

High-resolution AOI systems scan the inner and outer layers. They find trace defects, missing pads, solder mask misalignment, and other visual issues. This helps catch problems early, saving money.

100% Micro-sectioning TEST

100% Micro-sectioning TEST

We use micro-sectioning to check the inside of the PCB. By cutting a small sample and viewing it under a microscope, we can inspect via plating, layer alignment, and bonding quality. This helps make sure every board is strong and reliable.

100% Final Quality Control (FQC)

100% Final Quality Control (FQC)

Before packaging, each board gets a detailed final inspection. We check dimensions, surface finish, hole quality, silkscreen accuracy, and overall workmanship. This all meets IPC Class 2 or Class 3 standards.

All quality records are traceable and available upon request. We stand behind every board we ship.

Rigid PCB Frequently Asked Questions

How many layers can a rigid PCB have?
A rigid PCB can have single layer, 2 layers, or multiple layers. Simple products often use single-sided or double-sided rigid PCBs. More complex designs may use 4-layer, 6-layer, 8-layer, 10-layer, or higher-layer boards. HXD supports custom rigid PCB manufacturing up to 32 layers, depending on design needs and manufacturing requirements.
What materials are used for rigid PCBs?
Common rigid PCB materials include standard FR-4, High-Tg FR-4, Rogers, PTFE, aluminum base, and copper base materials. FR-4 is used for most standard electronics. High-Tg FR-4 offers better heat resistance. Rogers and PTFE are used for RF and high-frequency designs. Aluminum and copper base materials help improve heat dissipation.
Can rigid PCBs support controlled impedance?
Yes. Controlled impedance is often required for high-speed signals, such as USB, PCIe, Ethernet, DDR, and RF circuits. Final impedance values should be confirmed with the PCB manufacturer before production.
What surface finishes are available for rigid PCBs?
Common surface finishes for rigid PCBs include HASL, lead-free HASL, ENIG, OSP, immersion silver, and immersion tin. ENIG is often used for high-density designs, while HASL is common for standard and cost-sensitive PCB projects.
Are rigid PCBs suitable for high-speed designs?
Yes. Rigid PCBs are widely used in high-speed electronic products. With the right stackup, material, impedance control, and reference plane design, rigid PCBs can support high-speed signals and reduce EMI. For advanced designs, materials such as High-Tg FR-4, low-loss laminates, Rogers, or hybrid stackups may be used.
What files are needed for rigid PCB manufacturing?
For rigid PCB manufacturing, you usually need Gerber files and drill files.
You also need stackup information, board thickness, and copper thickness.
Include surface finish, solder mask color, and quantity.
For controlled impedance boards, impedance requirements and trace width details should also be provided. Assembly projects may also need BOM and pick-and-place files.
Can HXD provide custom stackup support?
Yes. HXD can provide custom stackup support for rigid PCB projects. We can help review layer count, material selection, core and prepreg thickness, copper weight, impedance targets, and via structure. This helps improve manufacturability and reduce design risks before production.
What is the typical lead time for rigid PCB production?
The lead time for rigid PCB production depends on layer count, board complexity, materials, surface finish, quantity, and testing requirements. Simple rigid PCBs usually have shorter lead times. High-layer, HDI, controlled impedance, or special material boards may need more production time. Contact HXD with your files for an accurate lead time.
