Surface mount resistors, along with other surface mount electrical components, are widely utilized. Surface mount technology is currently used to build the majority of consumer and professional/industrial devices.
SMT enhances production by allowing for extremely high degrees of automation. It also increases dependability, allows for larger levels of functionality to be produced within an acceptable size, and greatly cuts costs.
Surface mount technology allows electrical components to be easily positioned on a printed circuit board and then soldered in place using an automated process.
As a result, in terms of quantity, surface mount resistors are the preferred form for practically all electronic equipment.
Surface mount resistors provide the same functionality as axially leaded resistors, but with less power dissipation and often reduced stray inductance and capacitance, among other things.
SMD resistors, are available in all common values, from E3 to E192, as well as certain specialties if required. Also, they come in a range of sizes, some of them are now quite small and difficult to handle manually.
Surface Mount Technology is a type of electronic assembly that involves attaching electronic components to the PCB’s surface. Surface mounted devices are electronic components that are installed in this manner (SMD). SMT was created to reduce production costs while maximizing PCB area use.
Surface mount technology’s introduction
In the 1960s, surface-mount technology was created, and by the 1980s, it was widely employed. They were widely employed in high-end PCB assembly by the 1990s. Metal tabs or end caps were added to traditional electrical components so they could be mounted directly to the board surface.
This eliminated the requirement for traditional wire leads to pass through drilled holes. SMT allowed for significantly smaller components and more frequent positioning of components on both sides of the board than through-hole installation.
Surface mounting allows for more automation, lowering labor costs and increasing manufacturing rates, leading in more sophisticated PCB design and development.
Automated Simplified Production
Through-Hole Electronic Components have leads that must be manually placed into Plated Thru-Holes. These leads must be molded, bent, and chopped.
With SMD Components, this is not the case. They may be placed on the board automatically with an Automatic SMT Pick and Place Machine. This lowers the cost of processing and output.
PCB Flexibility
Surface Mount Technology gives great flexibility in terms of PCB material and design because SMD components are placed or soldered directly on the board’s surface. Only SMT makes Flex PCB and Rigid-Flex PCB viable.
Smaller and Slim PCB
SMD Components are 60-80% smaller than their Thru-Hole Counterparts, resulting in a slimmer PCB. These components are also substantially less in weight. As a result, they take up less room on the SMT PCB, making it smaller and slimmer.
High Signal Transmission and High Frequency
SMT PCB Assembly can handle high density, namely on Double Sided and Multiplayer PCBs, and can transmit high speed signals due to the low latency.
RF interference is also decreased with SMD components since they have no or short leads. SMT PCB Assembly is also more vibration resistant and produces less noise.
Reduced Board and Material Costs
SMT PCBs are smaller, and there are no Plated Thru-Holes required. Many SMD components are also less expensive than Thru-Hole Electronic Components.
This lowers the cost of SMT PCB manufacturing. Surface Mount Assemblies are smaller and slimmer, resulting in lower handling, packing, and transportation costs.
Conclusion
Surface mount resistors (SMDs) are mass-produced in the billions and are utilized in virtually every electronic circuit because they are simple to attach into printed circuit boards.
SMD resistors are currently quite simple to manufacture and may be bought for a very low price, especially when used in large quantities. SMD resistors have become the most used resistor technology.
