Surface mounting is an effective technique for PCB assembly if the correct process is followed. Printed circuit boards are typically laminated and integrated with pads. These pads are plated with gold or silver tin-lead. The pad is coated with solder paste; this process is called screen printing.
Various conveyor systems can be used to transport electrical components that will be mounted on the surface of the PCB. The conveyor belt is used for automatic transfer in a paper/plastic belt wound on a reel. Sometimes plastic tubes can also be used for similar mechanisms. However, for large, well-designed circuits, it is recommended to use a static-free tray for delivery.
After placing the components on the board, the boards are moved to the reflow oven by means of a conveyor belt. The high temperature in the reflow oven causes the solder particles to melt and the electronic components adhere to the surface of the board. There are various other methods that can be used for weldings, such as using a fluorocarbon liquid or hot gas convection.
The SMT assembly method for printed circuit boards is very important for compact circuit design used in technologically advanced electronic devices. Surface mount technology has the following advantages when used in PCB assembly:
This technology saves a lot of space and is therefore ideal for compact PCBs
The installation process produces less noise than traditional processes
Using this technology, electronic components can be placed on both sides of a printed circuit board
Using the SMT method can greatly increase component density and the number of interconnections between components
SMT assembly method is very suitable for custom PCB
This technique is useful when assembling under shaky and vibratory conditions
This technology is very cost-effective
For high-end and sophisticated boards, SMT PCB assembly technology is perfect. It saves time, costs and delivers outstanding results.
