The History of SMT
smt refers to surface assembly technology, also known as surface mount or surface mount technology, is a popular technology and process in the electronic assembly industry. The basic process flow of smt includes solder paste printing, parts mounting, reflow welding, AOI optical inspection, maintenance and so on. The SMT process can be divided into five processes, including single-side assembly and double-side assembly.
After half a century's development, SMT processing has become very mature in the modern electronic processing industry. Half of the processing industry. The technical staff of Lianlian Technology will introduce you to the following smt patch processing development process.
How SMT patch processing is produced
According to documented historical research, smt patches originated in Europe in the mid-to-late 20th century. After printing the solder paste onto the ceramic substrate, they mounted the lead-free monolithic ceramic capacitor MIC, the installed IC and the short-pin transistor onto the ceramic substrate by hand patching. After reflow welding, assembly is completed. This is the earliest prototype of smt.
How has smt developed in China
smt technology was first introduced in China in the 1980s. But as early as the early 1970s, Chinese electronics technicians began to pay close attention to the development of smt technology abroad. In China, the first person to use smt patches was a color TV coordinator in the color TV industry. For example, the Panasonic color TV coordinator changed from A Type A to a Type B electronic tuner, and the new tuner uses a large number of chip components. Under the guidance of the planned economy at that time, domestic color TV tuner factories began to introduce STM production lines. Imported models include Panasonic, Sanyo, TESCON, TDK, etc.
A long history of international smt development
Being the first to eat crabs, smt developed slowly in Europe and the United States. But it has grown rapidly in resource-poor Japan, largely because the Japanese are adept at learning from Western technology and innovation. In the late 1970s, Japan's large electronics conglomerates pioneered the development of automatic SMT machines. Slowly upgraded the patch machine from an in-house special device to a commercial general purpose device, and began to put it into the production of electronic products in large numbers.
Today, the development of SMT industry
After more than 30 years of development, smt technology has become increasingly mature. The late 1970s began to develop the patch machine enterprise has also become the industry giant in the patch processing. In China, smt has also grown from nothing to big, and has become the most widely used country in the world. The popularization of SMT processing has made a huge contribution to the development of our electronic processing industry.
Since 1985, China began to introduce SMT automatic SMT machine production line equipment for mass production of small electronic products. This year 2010 is exactly 25 years. For 25 years. SMT in China has been developed from scratch, from small to large, and has become the largest SMT application country in the world. The popularization of SMT has made a huge contribution to our country electronic information industry development. 25 years went by, and in a flash. Review the history of development, sum up experience, build on the past, look forward to the future, towards prosperity.
