Surface-mount connectors owned 57.3% of 2024 sales, reflecting automation’s pull across consumer and industrial lines. Automated pick-and-place lowers cost per joint and limits PCB drilling, supporting a 3.6% CAGR. Through-hole remains critical for power electronics, where larger solder barrels aid heat dissipation and shock resistance.

Rework on dense surface-mount boards is costly because neighboring components block access. IPC/WHMA-A-620 calls for tighter process windows that many legacy lines struggle to meet. Asia-Pacific maintains the strongest surface-mount infrastructure, whereas some North American facilities still favor through-hole for rugged assemblies in the wire-to-board connector market.

By Current Rating: Above-6 A Segment Accelerates

Connectors rated 1.1-3 A retained 41.5% revenue in 2024, serving mainstream signal paths. Yet above-6 A designs post a 5.3% CAGR thanks to EV traction inverters and data-center power shelves. Up-to-1 A parts meet low-power IoT needs and lose share only slowly. The 3.1-6 A class bridges industrial controls and mid-power automotive loads.

HC-Stak illustrates how aluminum cabling plus better thermal paths shrink size by up to 30%. Thermal-electrical optimization studies confirm that welded conductor reinforcements extend lifetime more than increasing cross-section alone. These insights steer R&D budgets across the wire-to-board connector market.

By Orientation: Vertical Growth Outpaces Right-Angle

Right-angle formats kept 52% share in 2024 because they route harnesses neatly along boards. Vertical mounts, however, climb at 6.1% CAGR as handset and IoT designers cut device thickness. Vertical layouts improve airflow but raise stack-up height, demanding layout trade-offs. Signal path geometry also shifts impedance profiles; 112 Gbps links now push orientation to the design front-line.

Assembly houses favor whichever orientation reduces pick-and-place errors. Consequently, orientation choice tightens collaboration between electrical and manufacturing engineers inside the wire-to-board connector market.
