Different Types of Rigid PCB

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

Single-Sided PCB: Conductive traces are only designed on one side of the substrate. It has a simple structure and so the production process is a very mature process. Also the cost is the lowest production cost.

Double-Sided PCB: Conductive circuits are designed on both sides of the substrate. Electrical connections between layers are made through Plated Through Holes (PTH). Compared to single-sided boards, double-sided PCBs offer much higher wiring density. This allows for more components and supports more complex circuit designs.

Multilayer PCB: Multilayer PCBs consist of three or more conductive layers separated by insulating materials. These layers are interconnected using advanced via technologies, such as Through-Hole, Blind Vias. Designed for high-performance systems, we provide custom solutions including 4-layer PCBs, 8-layer PCBs, and 10-layer PCBs to meet your specific requirements.

What is Rigid PCB？

Rigid PCB is a type of printed circuit board that cannot be bent or folded. It is the most common type of PCB in the industry. Rigid PCBs are applied in almost all mainstream electronic products, such as laptops, desktop computers, mobile phones, and televisions. The base material of rigid PCB is typically a glass fiber reinforced material. It can give PCB higher mechanical strength and allow it to operate stably in high temperatures and complex working environments.

HXD has mature manufacturing experience and a strict quality control system. Whether your project requires cost-effective single/double-sided PCBs or advanced multilayer HDI boards, we can provide a one-stop production from full-process service from DFM (Design for Manufacturability) and quickturn to mass volume mass production.

Rigid PCB Stackup

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.
