It offers strong mechanical support, better heat resistance, and is ideal for high-power and high-stress environments. Q4. Can THT and SMT be used on the same PCB? Yes, combining both allows designers to balance durability (THT) and space-saving (SMT) needs. Q5. What industries still use through-hole technology? Aerospace, military, transportation, industrial, and power electronics still rely on THT for reliability. Q6. Is surface mount better than through-hole? SMT is better for compact, high-volume builds, but THT is stronger and more durable. Q7. Is SMD soldering better than through-hole? SMD soldering is faster and smaller, but through-hole is better for durability and power. Q8. What are the applications of through-hole technology? Through-hole technology is widely used in engine control modules, aerospace communication boards, high-voltage regulators, and factory automation systems, where durability, stability, and resistance to vibration are non-negotiable.
