What is THT(Through-HoleTechnology) andWhen Should YouUse Itwwwwww..hhjjeetteecchh..iinn
In the world of electronic manufacturing, PCBs are the backbone thatholds various components together, ensuring they workharmoniously. Among the many technologies used for PCBfabrication, Through-Hole Technology (THT) stands out for itsmechanical robustness and time-tested reliability.But what is THT? Let’s understand this better.Through-Hole Technology (THT) provides a strong mechanicalconnection and high durability, making it ideal for large, heavy, highpower components and applications in harsh environments wherereliability under stress, vibration, and extreme temperatures is critical.At HJE Tech India Pvt. Ltd., we are a trusted supplier of advancedSMT and THT equipment for the electronics manufacturing industry.In this presentation, we’ll delve into what is THT, its advantages, andwhen manufacturers should use it.INTRODUCTIONwwwwww..hhjjeetteecchh..iinn
Let’s break it down, what is THT, how does it work, and when to use it clearly andpractically, without any jargon.What is Through-Hole Technology (THT)?Through-Hole Technology is a PCB assembly method where component leads areinserted into pre-drilled holes in the printed circuit board (PCB) and soldered on theopposite side.Unlike SMT components that sit on the board’s surface, THT components physicallypass through the PCB. That simple difference creates a surprisingly strong mechanicalbond.Historically, THT was the predominant method for PCB fabrication, even before the riseof SMT, and it remains favoured in specific applications for its unique benefits.A COMPREHENSIVE GUIDE TO WHATIS THT: WHEN TO USE ITwwwwww..hhjjeetteecchh..iinn
How does the THT Assembly Work?It forms strong mechanical and electrical bonds, making it idealfor durable, high-stress applications such as connectors andhigh-power circuits. It is often used with wave soldering aftermanual or automated placement.The THT process usually follows these steps:Hole drilling on the PCBManual or automated component insertionWave soldering or selective solderingInspection and testingThis approach may look old-school, but it delivers unmatchedstrength where it counts.wwwwww..hhjjeetteecchh..iinn
When reliability matters more than miniaturisation, Through-HoleTechnology earns its place. Here’s when to use THT in electronicmanufacturing:High Reliability ApplicationsIf your product goes into automotive systems, industrial machinery,power supplies, or medical equipment, THT is often non-negotiable.These environments punish weak solder joints.High Current or High-Voltage CircuitsTHT components handle higher electrical loads better. Thick leadsand deeper solder joints improve current flow and heat dissipation.Prototyping and RepairTHT makes it easier to handle soldering, modification, and inspectionof large components during early design stages or for field service.WHEN TO USE THROUGH-HOLETECHNOLOGY?wwwwww..hhjjeetteecchh..iinn
Products Facing Constant StressThink vibration, shock, or frequent handling. THTcomponents simply stay put longer.Low Volume and Custom Buildsor PrototypeBuildsEarly-stage startups and R&D teams love THT because:Components are easier to sourceManual insertion reduces tooling costsRepairs and design changes are simplerwwwwww..hhjjeetteecchh..iinn
Through-Hole Technology offers various advantages in electronicmanufacturing, including:1.Durability: THT creates a permanent mechanical and electricalconnection between the component and the board, making itideal for high-reliability and durability components.2.High Power Handling: It is suitable for high-power components,making it an ideal choice for power electronic equipment.3.Cost-Effective Solution: The THT process is relativelystraightforward, making it a cost-effective solution for PCBmanufacturers.4.Ease of Repair: If a component fails, the THT component is easyto replace, facilitating repair and maintenance.5.Lead Time: THT components have longer lead times as comparedto surface mount technology (SMT), making them perfect forapplications where long-term reliability is essential.ADVANTAGES OF THROUGH-HOLETECHNOLOGYwwwwww..hhjjeetteecchh..iinn
