Board families

PCB types made in China

Each board family below is a distinct manufacturing process. Capability is recorded per product series, so a factory that advertises a high layer count on one line is not automatically credited with it on another.

Aluminum PCB

Metal-core boards that use an aluminum base plate to move heat away from components, common in LED lighting and power conversion.

Typical layers: Usually single-sided metal core; multilayer variants recorded separately

Aluminum baseThermally conductive dielectricCopper foil

See factories and checks

Flexible PCB

Circuits built on flexible polyimide film that can be bent or folded, used where a rigid board or a cable harness will not fit.

Typical layers: Single-sided, double-sided and multilayer flex recorded separately

PolyimideCoverlayAdhesiveless copper clad laminate

See factories and checks

HDI PCB

High density interconnect boards built with build-up dielectric, laser-drilled microvias and fine lines instead of only mechanically drilled through vias.

Typical layers: Recorded as the build-up structure, for example 1+n+1 or 2+n+2

Build-up dielectricRCCHigh-Tg FR-4

High Frequency PCB

Boards built on low-loss RF laminates where dielectric constant, dissipation factor and impedance consistency drive performance.

Typical layers: Hybrid stack-ups recorded with the laminate used on each layer

RogersPTFEHydrocarbon ceramicFR-4 hybrid

See factories and checks

Multilayer PCB

Three or more copper layers bonded into one board, used where routing density and controlled impedance make double-sided construction impractical.

Typical layers: Recorded per product series, never as one site-wide maximum

FR-4High-Tg FR-4Polyimide

See factories and checks

Rigid-Flex PCB

A board combining rigid sections and flexible sections in one laminated assembly, removing the connectors between the two.

Typical layers: Rigid layer count and flex layer count recorded separately

PolyimideFR-4No-flow prepreg

See factories and checks

Looking for layer count, line width, drill size or impedance instead? That is a capability filter, not a board type. The two sections are kept separate on purpose so the same keyword is not chased by two pages.
