0.4mm Pitch Board-to-Board Connector – Technical Guide

Compact and Reliable PCB Interconnection Solutions

As electronic devices become smaller and more sophisticated, engineers require compact and reliable interconnection solutions. The 0.4mm pitch board-to-board connector is designed for high-density PCB applications where space efficiency and stable electrical connections are essential.

SOLEPIN provides board-to-board connector solutions for various electronic applications, supporting OEM and ODM requirements.

What Is a 0.4mm Pitch Board-to-Board Connector?

A 0.4mm pitch board-to-board connector is a fine-pitch connector used to establish electrical connections between two printed circuit boards.

The 0.4mm pitch refers to the center-to-center distance between adjacent contacts.

These connectors are commonly used in compact electronic assemblies requiring high connection density.

Key Features

• Compact Design: 0.4mm contact pitch helps reduce PCB space requirements.

• High-Density Connections: Suitable for applications with limited board space.

• Surface-Mount Technology: SMT configurations support automated PCB assembly.

• Multiple Configurations: Contact count, stacking height, and mating structure depend on the selected series.

• Reliable Interconnection: Proper connector selection and PCB layout help maintain stable electrical connections.

Typical Applications

0.4mm pitch board-to-board connectors may be used in:

• Industrial electronic equipment

• Compact control modules

• Communication devices

• Consumer electronics

• Embedded electronic systems

• High-density PCB assemblies

How to Choose the Right Connector

When selecting a 0.4mm pitch board-to-board connector, engineers should consider:

1. Number of contacts

2. Required board-to-board stacking height

3. Rated current and voltage

4. Operating temperature

5. Mating cycle requirements

6. PCB footprint and mounting method

Electrical and mechanical specifications should always be confirmed using the selected product's official datasheet.
