(Summary description)When preparing to design a printed circuit board, some component surface mounting and through-hole packaging need to be carefully considered. Compared with traditional through-hole component packaging, SMT surface mount has many advantages. The following Sanjing will take you to understand:
Most parts can be installed on the circuit board using automated equipment. High-capacity parts (such as passive components) are loaded from the reel into the pick-and-place machine, while other parts are loaded with a tube feeder or pallet, and are assembled manually. Compared with PTH parts, there is a big difference.
In terms of size and volume, SMT parts are usually smaller than PTH parts because there are no longer leads that need to be inserted and soldered into the holes, so more components can be installed on the board. At the same time, because more SMT components can be installed on...

When preparing to design a printed circuit board, some component surface mounting and through-hole packaging need to be carefully considered. Compared with traditional through-hole component packaging, SMT surface mount has many advantages. The following Sanjing will take you to understand:

 

Most parts can be installed on the circuit board using automated equipment. High-capacity parts (such as passive components) are loaded from the reel into the pick-and-place machine, while other parts are loaded with a tube feeder or pallet, and are assembled manually. Compared with PTH parts, there is a big difference.

 

In terms of size and volume, SMT parts are usually smaller than PTH parts because there are no longer leads that need to be inserted and soldered into the holes, so more components can be installed on the board. At the same time, because more SMT components can be installed on the board, the signal path on the board is shorter.

 

Compared with PTH parts, SMT parts can provide better signal integrity for the PCB and reduce the amount of heat generated. In addition, SMT parts are generally cheaper than PTH parts, so the demand for SMT parts is greater than PTH parts.

 

 

However, everything has two sides. SMT surface mount also has some shortcomings. For example: 1. When repairing small SMT parts, although the repair technicians are very good at using tweezers and magnifying glasses to repair, the parts are so small that they are searching, desoldering and All face great challenges when replacing. At the same time, the handheld soldering iron can easily damage nearby parts.

 

Secondly, although SMT components are small and can provide better electrical performance, PTH components are needed if they are to be applied to high-power PCBs.

 

Third, SMT components usually use disposable connectors, but in applications where frequent connections and disconnections should be used, stronger connectors should be used. At this time, PTH is the best choice because its solder through-hole leads are better than Surface-mounted welded parts have better mechanical strength.

 

The above is about the advantages and disadvantages of using SMT to assemble PCB, I hope it can be helpful to everyone!
