Taiwan Connector Industry Supply Chain

Overview

Connectors are critical components that enable signal and power transmission across electronic systems.

They include:

• Connectors (board-to-board, wire-to-board, wire-to-wire)

• Cables and wire harnesses

• Sockets, plugs, and I/O interfaces

As the “nervous system of electronics”, connector quality directly impacts:

• Signal integrity

• Power stability

• Overall system reliability

With the rise of AI, 5G, and high-speed computing, connectors are becoming increasingly complex, high-frequency, and performance-critical.

Supply Chain Structure

1. Upstream: Materials

Upstream materials account for 40–70% of total production cost.

Key materials include:

• Metal materials (largest share)

  • Brass, phosphor bronze (for terminals)
