PCB Manufacturing Process
Why Choose OurPCB As Your High Speed PCB Manufacturer?
OurPCB operates two high-capacity factories in Shijiazhuang and Shenzhen, with over 10,000 square meters of combined production space.
We process high-speed multilayer PCBs on dedicated lines equipped with LDI exposure units, PTH copper sinking lines, and AOI stations optimized for fine-line trace analysis.
All impedance-controlled PCBs undergo staged inspection using optical AOI (automated optical inspection), flying probe continuity test, and 4-wire low resistance measurement systems.
Resistance testing accuracy reaches ±0.01 mΩ, essential for validating copper integrity in power-ground planes and differential trace pairs.
This multi-method inspection minimizes propagation delay mismatches and signal distortion in high-speed designs.
Our engineering and process teams evaluate every high-speed order before production release.
Stackup validation includes dielectric constant modeling, copper roughness correction, and impedance calculations per IPC-2141.
DFM review includes trace width/spacing, return path alignment, via clearance, and tolerance stacking for designs using PTFE, hydrocarbon, or ceramic-filled systems.
To ensure adhesion between inner layer cores and prepreg during lamination, all copper surfaces undergo brown oxide treatment and wet chemical cleaning.
This process creates a micro-etched copper oxide surface for optimal epoxy resin anchoring.
Controlled oxide thickness and pre-bond surface conditioning prevent delamination in high-aspect-ratio multilayer stackups during press cycles.
For high-speed PCB assemblies involving complex ICs, high-speed interfaces, or tight-pitch components, OurPCB performs X-ray inspection, optical joint analysis, and continuity testing using programmable digital power supplies.
Signal-critical paths such as DDR, PCIe, and USB interfaces are verified for routing integrity and solder joint performance under post-reflow conditions.
These inspection steps ensure clean impedance transitions, matched routing paths, and electrical compliance across the complete assembled board.
As a high speed PCB manufacturer, we manage process yield not only at the final test but also across drilling, copper plating, lamination, soldermask, surface finish, and routing.
Each stage includes AOI or metrology checkpoints using microscopes, resistance testers, or X-ray inspection.
This step-by-step product quality check prevents compounding defects in high-speed PCBs, where a single misregistration or plating void can result in signal reflection or impedance failure.

When do you need a High Speed PCB Manufacturer?
You need a high speed PCB manufacturer when a standard PCB isn’t sufficient for your needs. High-speed PCBs are necessary when signal behavior is affected by transmission line effects, which occur when the trace length exceeds one-tenth to one-twelfth of the signal’s wavelength.
For example, a 1 GHz signal has a wavelength of approximately 30 cm on FR4, meaning any trace longer than 2.5 to 3 cm must be treated as a transmission line. A high-speed layout is also required when the trace delay exceeds 20% of the signal’s rise time, a common issue in fast-switching digital systems where rise times are under 1 ns.
If your design includes interfaces like DDR4/DDR5, PCIe Gen 4/5, USB 3.2, SATA, or MIPI, it qualifies as high-speed. Other indicators include differential pairs, matched trace routing, layer-specific signal referencing, or the need to simulate crosstalk, reflection, and skew across interconnects. These conditions require controlled routing, accurate dielectric modeling, and trace geometry tailored to maintain timing integrity across layers.

High Speed PCB Manufacturer FAQs
What is a High Speed PCB?
A high-speed PCB is a circuit board where signal delay, edge rate, and trace geometry interact in ways that require controlled design rules and fabrication processes. This occurs when the signal’s rise time is short enough that the interconnect behaves like a transmission line, most often when trace delay exceeds 20% of the rise time or the routing exceeds λ/12.
Interfaces like PCIe Gen4, DDR5, and USB 3.2 fall into this category. These boards require matched trace lengths, reference plane continuity, and carefully constructed stackup structures across multilayer PCB builds to minimize signal distortion and skew.
Which materials do you recommend for high-speed PCB fabrication?
We fabricate high-speed PCBs using low-loss materials, including PTFE-based systems such as Rogers RO3000, Panasonic R-5775(M6), and Arlon 25N, with dielectric constants between 2.2 and 3.9.
These materials support frequencies up to 25 GHz and maintain signal fidelity by reducing insertion loss and dispersion. For sub-2 GHz designs, we use high-Tg FR4 systems like TU-883, balancing cost with adequate performance.
All laminates are selected to match target layer count, copper weight, and routing density, and are documented in our controlled material list for high-speed builds.
How do you ensure impedance control in high-speed PCB stackups?
Signal behavior is controlled by defining a precise stackup, maintaining trace spacing tolerances, and simulating rise-time impacts using IPC-2141. Our engineering team validates layer order, material Dk/Df, and copper roughness before fabrication.
The inner layer routing is matched to ±10 mil for differential pairs, and all critical paths are aligned with uninterrupted reference planes. Each board includes impedance coupons and undergoes TDR testing to confirm signal integrity across transitions.
These steps are implemented in prototype PCB orders and production to preserve waveform accuracy and reduce reflection and skew.
Do you manufacture PCBs with HDI features and advanced via structures?
Yes, we manufacture high-speed PCBs with stacked HDI architectures up to 8+2+8 layers using blind, buried, and laser-drilled microvias down to 3 mils. Resin-filled via-in-pad is applied for fine-pitch components such as BGA and SiP.
Laser hole depth control is maintained to ±20 μm, and via cap flattening ensures clean surface mount compatibility. These features are standard in rigid-flex PCB designs and advanced interconnect modules, where vertical routing and limited pad escape space demand non-mechanical solutions with verified fabrication capabilities.
What testing methods are used to validate high-speed PCB performance?
Each high-speed PCB undergoes AOI, flying probe, and 4-wire resistance testing to validate copper continuity, trace geometry, and hole-to-pad registration. Impedance test coupons are analyzed using TDR to confirm trace behavior within ±5 Ω of modeled targets.
For builds with via-in-pad, stacked vias, or filled microvias, X-ray imaging is used to detect plating voids and copper depression. Final acceptance follows IPC-6012E Class 3 criteria, including statistical validation of trace fidelity, pad alignment, and dielectric thickness, ensuring compliance with customer specs and internal quality standards.
What’s the difference between high-speed and high-frequency PCBs?
High-speed PCBs are designed for digital signals that switch rapidly and depend on precise timing. Performance is shaped by trace length, rise time, and overall signal integrity, especially in circuits using interfaces like USB, DDR, and PCIe.
High-frequency PCBs carry analog signals such as RF or microwave, where waveform shape, phase alignment, and dielectric behavior must remain consistent.
While both use low-loss materials and controlled stackup configurations, high-speed boards focus on maintaining edge transitions and timing margins. In contrast, high-frequency designs manage continuous waveform behavior across high-frequency bands.
