What Is a Board-to-Board Connector?

A board-to-board connector is an electronic connector that electrically and mechanically connects one PCB directly to another PCB.

A simplified arrangement is:

PCB 1 → Board-to-Board Connector → PCB 2

This eliminates the need for a separate cable in many designs and can create a compact, organized electronic assembly.

Common Applications of Board-to-Board Connectors

Board-to-board connectors are commonly used in:

  • Computers
  • Industrial control systems
  • Embedded electronics
  • Robotics
  • Automation equipment
  • Communication devices
  • Consumer electronics
  • Medical electronics
  • Measurement equipment
  • Power electronics
  • IoT devices
  • Custom PCB assemblies

Why Use Board-to-Board Connectors?

Board-to-board connectors can provide several advantages:

  • Compact PCB-to-PCB connection
  • Reduced wiring
  • Organized assembly
  • Easy PCB integration
  • Space-efficient designs
  • Multiple electrical contacts
  • Suitable for modular electronics
  • Convenient assembly and servicing

They are especially useful when multiple circuit boards need to be installed within a limited enclosure.

Board-to-Board Connector Types

Pin Header Connectors

Pin headers are simple PCB connectors consisting of rows of metal pins mounted in an insulating housing.

They are commonly used for:

  • PCB interconnection
  • Development boards
  • Embedded systems
  • Prototyping
  • Custom electronics

Socket Connectors

Socket connectors provide mating receptacles for compatible pins or headers.

They can be useful when boards need to be connected and disconnected during servicing or assembly.

Stacking Connectors

Stacking connectors are designed to maintain a specific distance between PCBs.

A typical arrangement is:

Top PCB

Stacking Connector

Bottom PCB

This can be useful for compact multi-board electronic systems.

Right-Angle Connectors

Right-angle connectors allow boards or cables to connect at approximately 90 degrees, depending on the connector design.

They can be useful when enclosure space or PCB orientation requires a side-entry connection.

Board-to-Board Connector Specifications

Specification What to Check
Connector Type Header, socket, stacking, etc.
Pitch Distance between contacts
Number of Pins Required contact count
Orientation Vertical or right-angle
Mounting Through-hole or SMD
Mating Type Compatible connector
Height Required board spacing
Contact Material Specified contact construction
Current Rating Required electrical load
Voltage Rating Circuit requirements
PCB Footprint Board compatibility

What Is Connector Pitch?

Pitch refers to the distance between the centres of adjacent contacts.

Common PCB connector pitches include:

  • 0.5 mm
  • 0.8 mm
  • 1.0 mm
  • 1.27 mm
  • 2.0 mm
  • 2.54 mm

The required pitch depends on the PCB design and mating connector.

Important: A connector with the correct number of pins may still be incompatible if the pitch or mechanical configuration is different.

How to Choose the Right Board-to-Board Connector?

1. Check the PCB Layout

Determine where the connector will be installed and how the second PCB will be positioned.

2. Check the Pitch

Match the connector pitch with the PCB footprint and mating component.

3. Count the Contacts

Make sure the connector provides the required number of electrical connections.

4. Check the Orientation

Determine whether you need:

  • Vertical
  • Horizontal
  • Right-angle

5. Check Board Spacing

For stacked PCBs, connector height is particularly important.

Measure the required clearance between the boards before selecting the connector.

6. Check Mounting Method

Determine whether your PCB requires:

  • Through-hole mounting
  • Surface-mount mounting

7. Check Electrical Ratings

Verify:

  • Current rating
  • Voltage rating
  • Contact resistance
  • Insulation requirements

These specifications should match the intended circuit.

Board-to-Board Connectors for PCB Assembly

Board-to-board connectors are particularly useful when an electronic product contains multiple PCBs.

For example:

Main PCB → Connector → Display PCB

or:

Controller PCB → Connector → Interface PCB

This modular approach can make product design and servicing more convenient.

Board-to-Board Connectors in Computers

Computers and other electronic devices can contain multiple circuit boards that require compact interconnection.

Board-to-board connectors can be used in:

  • Motherboards
  • Expansion boards
  • Interface boards
  • Control boards
  • Internal modules
  • Compact electronic assemblies

For wire-based connections, explore Wire Terminal Connectors.

Board-to-Board vs FFC/FPC Connections

Another common way of connecting two PCBs is through a flexible cable.

Feature Board-to-Board FFC/FPC
Connection Direct PCB-to-PCB PCB → Flexible Cable → PCB
Flexibility Limited by connector design High
Space Compact Useful for separated boards
Movement Limited Better for moving/folding assemblies
Typical Use Stacked/modular PCBs Displays, printers, compact electronics

Explore FFC/FPC and FFC Cables for flexible PCB connection solutions.

Common Board-to-Board Connector Problems

Problem Possible Cause
Connector Does Not Mate Incorrect connector type
Pins Misaligned Wrong pitch or orientation
PCB Does Not Stack Correctly Incorrect connector height
Intermittent Connection Damaged or contaminated contacts
