PCBA, short for Printed Circuit Board Assembly, is a technology that fixes electronic components to a printed circuit board and connects them. PCBA history is back to the 50s of the 20th century, when electronic components were still soldered to circuit boards by hand. As the number of electronic components increases and boards become smaller, manual soldering becomes increasingly difficult.
In 1961, the first automated PCBA process was born in the United States. Using machines and hot melt adhesive methods, electronic components are mounted on a printed circuit board. This technology not only improves the production efficiency of PCBA for lots of manufactuers and suppliers, but also reduces human error, making PCBA more and more popular in the electronics manufacturing industry.
In the late 1960s, surface mount technology (SMT) began to be used in PCBA production, which allows electronic components to be mounted directly on the surface of a printed circuit board rather than connected through holes. This technology allows circuit boards to become more compact and is therefore becoming more common in electronics.
Today, PCBA has become one of the key technologies for many factories in modern electronics manufacturing in China. With the continuous development of technologies such as the Internet, smart home and artificial intelligence, the application range of quality PCBA will become more and more extensive.
