As PCB manufacturer China knows that，The best printed circuit board manufacturing acknowledges the fact that real estate is limited on a PCB. Every millimeter matters, and even a sliver of wasted space can make a project less effective and more expensive. Surface mount technology takes up less space and is lighter than through-hole mounting, making it a highly desirable form of component application.

The benefits do not end there. SMT methods lend themselves much better to quick manufacturing and assembly, meaning that the cost of producing boards is lower and is done at much faster speeds than alternative methods of application. The drilling required for through-hole mounting made assembly more expensive, and had the potential to create debris that could cause issues with signals. Additionally, SMT methods boast lower induction and resistance.

With so many advantages to using surface mount technology, why wouldn’t you want to use it? As it turns out, in several instances alternatives work better.
