Understanding the Development and Application of SMT
SMT patch: Historically speaking, the PCBA installation component SMC company/surface mount technology was invented by advanced technology countries in Europe and the United States in the mid-1960s Print solder paste, thick film resistor and bonding pad on the ceramic substrate where the circuit is located. Paste lead-free monolithic ceramic capacitor MLC, short lead transistor called "sesame tube" and its integrated circuit manually, and then reflow solder to complete the assembly. This is the most basic SMT method Although the academic term "SMT" did not appear at that time, and a separate scientific and technological category had not yet been formed, this advanced assembly process has gradually taken shape, showing strong vitality
The Chinese PCB electronic component academia has been paying attention to the development trend of SMC/SMT appeared in the world as early as the early 1980s Chinese electronic technicians have been tracking the development of SMT chip processing technology in foreign countries in the late 1970s and early 1980s, and applying STM technology in a small range The first large-scale introduction of STM production lines in China began in the early and middle 1980s The background is the introduction of technology in China's color TV industry Matching color TV tuners, such as Panasonic color TV tuners, have been changed from A-type electronic tuners to B-type electronic tuners. A large number of chip components are used in the new tuners Under the guidance of the planned economy at that time, domestic color TV tuner factories began to introduce SMT production lines, including Panasonic, Sanyo, Tesco, TDK, etc

In contrast, Europe and the United States, which were the first to form SMT technology, have made slow progress. Japan lacks resources, but is good at learning from the West and reinventing technology. In the mid-1970s, Japan accelerated the pace of development and application. At the end of the 1970s, a large Japanese electronic enterprise group took the lead in successfully developing an automatic chip mounter, which was gradually improved from an internal special equipment to a commercial general equipment for mass production of household electronic products. In the early 1980s, surface mount technology (SMT), as a new type of advanced electronic board level assembly technology, was officially launched due to the breakthrough in automatic placement of key process equipment. SMT wafer processing technology has been vigorously developed in the development and competition of developed national large electronic group companies. Since SMC/SMD has no leads or short leads, it can improve the high-frequency efficiency of electronic products. It is the earliest and most widely used electronic tuner for large capacity color TV. It was against this background that a large number of SMT related companies appeared in Japan in the 1970s. Gute Solar Power was founded on April 30, 1965, Malycom was founded in September 1973, and Tiancun Tiancun was founded on November 21, 1939. It can be seen that around the 1970s, some well-known SMT related companies in Japan were established one after another.
After more than 20 years of development, SMT technology has become increasingly mature and high-end. The original Japanese company has grown and become a well-known brand, while China's SMT has grown from scratch, from small to large. It has become the most advanced surface mount technology in the world. A country with large-scale SMT application. The popularity of SMT processing has made great contributions to the development of China's electronic information industry.
Looking forward to the future, Tiancun's lead-free solder paste has gradually replaced the lead containing solder paste, and has developed a low silver solder paste to fill the gap in the automotive electronics field; Various SMT peripheral test equipment of MALCOM are continuously developed and improved, from analog reflux to real-time furnace monitoring; GOOT has a full range of welding station models, the heating core is constantly improved, and the anti-static products occupy a leading position, which is in line with the trend. These signals indicate that surface mount technology abroad is becoming more mature, environmentally friendly and advanced.
With the rapid development of communications in China, computers, networks, and electronic products, SMT chip processing also has a very broad development prospect in China according to the requirements of the national development of strategic emerging industries As the largest and most important STM market in the world, China also has a huge market for SMT related products Then, China continues to introduce increasingly perfect surface mount technology from abroad to enrich its domestic technology and improve the quality of its various products PCB electronic products This is the general trend and there is no doubt about it
