Board types

Rigid PCB Constructions We Support

Choose the board construction around routing density, thermal load, mechanical requirements, material system, and target production volume.

Collection of rigid printed circuit board shapes and finishes

One manufacturing partner, multiple rigid-board platforms

Our current service page covers six rigid-board categories. Standard FR4 designs can be scaled from simple single-sided boards to dense multilayer builds, while High-Tg and metal-backed constructions address elevated thermal or mechanical demands.

Rigid-flex is included where rigid component sections need integrated flexible interconnects.

Cost-efficient

Single-Sided Rigid PCB

One copper layer on FR4 or CEM-1 for straightforward, cost-sensitive routing.

General purpose

Double-Sided Rigid PCB

Top and bottom copper layers with plated connections for greater routing density.

High density

Multilayer Rigid PCB

4–64 bonded layers with signal, power, and ground planes separated by dielectric spacing.

Thermal resilience

High-Tg Rigid PCB

High-Tg substrate systems such as S1000H and IT180 for repeated lead-free solder cycles.

3D integration

Rigid-Flex PCB

Rigid cores and flexible layers combined where compact folding or integrated movement is required.

Heat spreading

Metal-Backed Rigid PCB

Aluminum- or copper-backed constructions for LED, automotive, and power-conversion designs.

Materials & finishes

Build the Stack-Up Around the Application

A rigid PCB combines an insulating substrate, patterned copper, bonding prepreg, solder mask, and silkscreen into a fixed laminated stack. Material choice and surface finish affect temperature capability, solderability, contact life, signal behavior, and cost.

Discuss Your Stack-Up

Substrate

FR4, halogen-free, and High-Tg materials form the mechanically stable dielectric base. High-Tg options support lead-free soldering and sustained operation at elevated temperatures.

Copper layers

Patterned copper forms traces and power planes. Inner and outer copper weights can be selected separately for signal, current-carrying, and heat-transfer requirements.

Solder mask

LPI solder mask insulates copper, defines pad areas, and protects the board surface. Green, black, white, red, blue, yellow, and matte options are available.

Surface finish

ENIG, OSP, immersion silver, immersion tin, HASL, and lead-free HASL are selected around assembly, flatness, contact, storage, and RoHS requirements.

Silkscreen

Non-conductive epoxy legend supports component references, polarity markings, and assembly identification without interfering with exposed copper.

Quality control

Inspection Planned With the Build

Testing scope should match the board construction, density, impedance requirements, and end-use acceptance criteria. Confirm required reports and standards with the manufacturing enquiry.

AOI

Checks etched features and visible pattern defects against production data.

Electrical test

Flying-probe or fixture testing checks continuity and isolation.

Impedance test

Controlled traces can be verified to the agreed target and tolerance.

Microsection

Cross-section analysis supports plating and interconnect verification where specified.

How it works

    Agree the manufacturing specification, price, lead time, and any tooling or test requirements.

  4. Fabricate & Inspect

    Boards proceed through manufacturing, the agreed inspection plan, final packing, and shipment.

Application fit

When Should You Use a Rigid PCB?

Rigid PCBs are a strong fit when the assembly needs mechanical stability, precise component alignment, dense placement, or predictable high-volume production.

Stable product geometry

Supports fixed housings, heavier components, and assemblies that must remain flat and dimensionally stable.

Cost-focused production

Standardized FR4 processes, repeatable tooling, and established material systems support scalable manufacturing.

Shorter lead-time targets

Stocked rigid-board materials and repeatable fabrication steps help simplify production planning.

High component density

Stable substrates support dense BGA and QFN placement with controlled pad geometry and board thickness.

Frequently asked questions

Rigid PCB Manufacturing FAQs

What is the difference between rigid PCB and rigid-flex PCB?

Rigid PCBs are made entirely on solid FR4 or High-Tg laminate and remain flat after fabrication. Rigid-flex boards combine rigid sections with flexible polyimide layers, allowing defined areas to bend or fold during installation.

What is the minimum rigid PCB thickness?

The current service page lists finished rigid-board thicknesses down to 0.1 mm. Final feasibility depends on the material, panel format, copper distribution, layer count, tolerances, and handling requirements.

Can rigid PCBs use mixed copper weights?

Yes. The service supports differential copper thicknesses across inner and outer layers, allowing signal layers and power layers to use different copper weights. Mixed-weight builds require stack-up and resin-flow review.

How do you control dimensional stability on large rigid PCBs?

Dimensional control is managed through balanced stack-ups, controlled press cycles, core and prepreg matching, copper distribution review, profiling control, and warpage measurement after thermal processing.

What affects the final PCB quotation?

Layer count, board dimensions, quantity, material, copper weight, hole structure, line width and spacing, surface finish, impedance control, tolerances, testing, and delivery requirements all influence the quote.
