What do SMT, COB and PCBA processes mean?

SMT is a Surface Mount Technology (short for surface mount technology), which is called surface mount or surface mount technology. It is a circuit assembly technology in which surface assembly components without leads or short leads (SMC/SMD for short) are mounted on the surface of printed circuit board (PCB) or other substrates, and then soldered and assembled by reflow soldering or immersion soldering.

COB is a polysemous word, and its main intentions include: the English abbreviation of China Boxing Open; China Boxing Open is the highest level professional boxing competition held in Asia so far. The first match was held on April 5th, 20 10 in Guiyang, the capital of Guizhou province, the hometown of China's first Olympic boxing champion Zou Shiming.

The abbreviation of PCBA (Printed Circuit Board+Assembly), that is to say, the whole process of PCB blank loading by SMT and then by DIP plug-in, referred to as PCBA. This is a common way of writing in China, while the standard way of writing in Europe and America is PCB'A with "",which is called an official idiom.
