Through Hole Mounting Electronics Packaging Market Size, Share, Trends & Forecast Report

The Global Through Hole Mounting Electronics Packaging Market was valued at USD 8.6 billion in 2025 and is projected to reach USD 11.9 billion by 2032, growing at a CAGR of 4.8% during the forecast period.

 

Through hole mounting electronics packaging refers to electronic components whose leads or terminals pass through holes in a printed circuit board before being soldered or mechanically secured. It remains important for connectors, transformers, capacitors, resistors, power semiconductors and magnetic components that need strong board attachment or dependable electrical connections.

 

Demand is increasing as vehicles, industrial machines, power-conversion equipment and other durable electronic systems use more control and power electronics. Surface mounting remains dominant in compact electronics, but through-hole designs continue to be selected where larger components, higher electrical loads, mechanical stress or long operating life make stronger board connections necessary.

 

How IPC, RoHS and High-Reliability Standards Are Shaping Through-Hole Technology Demand

Regulations and electronics assembly standards continue to influence the use of Through-Hole Technology (THT), particularly where mechanical strength, solder-joint quality and long-term reliability are important. IPC-A-610 establishes widely used acceptability criteria for electronic assemblies, while J-STD-001 defines requirements for soldered electrical and electronic assemblies. Higher-reliability applications typically follow more stringent workmanship and inspection requirements, making THT relevant in aerospace, defense, industrial controls and other systems exposed to vibration, temperature changes or extended operating cycles.

PCB design requirements also affect through-hole component integration. IPC design guidance covering board geometry, hole dimensions, spacing and land patterns helps manufacturers maintain consistent component mounting and soldering performance. At the same time, environmental requirements such as the EU RoHS framework have accelerated the transition toward lead-free materials and compatible soldering processes, although specific exemptions remain for certain applications. These requirements increase attention to material selection, thermal performance and process control across THT production.

Demand remains strongest in sectors where reliability requirements outweigh the benefits of maximum PCB miniaturization. Aerospace and defense electronics continue to use qualified through-hole components where rugged construction, traceability and environmental durability are critical. Automotive and industrial power systems also retain THT for connectors, power components and larger passive devices that must withstand mechanical or electrical stress. In contrast, smartphones and other compact consumer products favor Surface Mount Technology because smaller footprints and highly automated production are more important.

Compliance requirements can also increase manufacturing complexity in high-reliability applications. More demanding inspection, documentation, soldering and qualification procedures require tighter process control and experienced electronics manufacturing capabilities. This favors established THT component and assembly companies that can meet demanding reliability requirements while supporting automotive, aerospace, defense, industrial and power-electronics applications.
