Through Hole Technology Application:
For complex boards Surface Mount Technology is regarded as a better option as the Through Hole Technology process takes longer and is more expensive.
Through-hole assembly has been appeared since the 1950s.
For large components, such as transformers and high power industrial PCBs that may be subject to high temperatures, stresses and vibrations, or in military and aerospace products that may experience extreme accelerations, collisions, or high temperatures, Through Hole Technology is usually the better choice. In most cases, the choice is not easy to make and blending both processes to gain the benefits of each is the best way out. Combining both processes during assembly, can give the strength and reliability of Through Hole Technology while preserving the overall cost and efficiency benefits of Surface Mount Technology.
Comparison of THT and SMT | |
Advantages of THT |
Advantages of SMT |
Strong component bond |
Faster & more cost-effective |
Better for larger components |
Allows for smaller, denser boards |
Better for components subject to mechanical stress |
Allows for more complex routing |
Better for high power and high temperature components |
Allows for double-sided component mounting |
Disadvantages of Through Hole Technology:
1) Through Hole Technology (THT) assembly process is more expensive than SMT.
2) THT's soldering process often makes the resulting solder points less reliable than SMT solder.
3) In Through Hole Technology (THT) the PCBs must be pre-drilled, which is both expensive and time-consuming. It also restricts components to one side of the board and limits the available routing area on multi-layer boards since the holes must be drilled through all the PCB's layers.
