Advantages of Surface Mount Technology & Through Holes Technology
Advantages of Surface Mount Technology
Smaller and Slim PCB: SMD components are 60-80% smaller in size than their Thru-Hole Counterparts. Weight of these components is also much less. Therefore they occupy lesser space on the SMT PCB thus making it Smaller and Slimmer.
PCB Flexibility: Since SMD Components are mounted or soldered directly on the Surface of the Board, Surface Mount Technology offers Great Flexibility in terms of PCB Material and Design. Flex PCB and Rigid-Flex PCB are possible only because of SMT.
Reduced Board and Material Cost: Size of SMT PCBs are smaller and there is No Need for any Plated Thru-Holes. Also cost of many SMD Components is lesser that Thru-Hole electronics components. This helps to reduce SMT PCB manufacturing cost. Since Surface Mount Assemblies are Smaller and Slimmer, there is reduced cost is terms of handling, packaging and transportation.
Automated Simplified Production: Through-Hole Electronic Components have leads that need to be inserted in the Plated Thru-Holes Manually. These leads need to be bent, shaped and cut. This is not the case with SMD Components. With Automatic SMT pick and place machine, they can be Automatically Placed on the Board. This reduces processing and production cost.
High Signal Transmission and High Frequency: SMT PCB assembly can support high density mainly on double sided PCB and multilayer PCB. Because of short delay these boards are capable of high speed signal transmission. Also because SMD Components have No Leads or Short Leads,RF interference is reduced. Also SMT PCB assembly offer more resistance to vibration and there is no to less noise.
Advantages of Through Holes Technology
Despite the rise of surface-mount technology, through-hole has held its own because of its reliability. Through-hole soldering creates a stronger bond between components and the board, making it perfect for larger components that will undergo high power, high voltage, and mechanical stress, including:
(1) Transformers
(2) Connectors
(3) Semi-conductors
(4) Electrolytic capacitors
Because components run through the board, they can also withstand more environmental stress. That is why through-hole technology is the preferred method for military and aerospace products that experience extreme accelerations or high temperatures. Their durability also makes them the best choice for prototyping and testing.
