Development status of chip processing in China
surface mount patch: HistorICally, SMC placement/SMD components were invented by advanced scientific and technological 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
Chinese electronic component academia has been paying attention to the development trend of SMC/SMT appeared in the world as early as the early 1980s In the late 1970s and early 1980s, Chinese electronic science and technology personnel began to track the development of SMT wafer processing technology abroad, and STM technology was applied in a SMAll range The first large-scale introduction of STM to China's railways 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 manufacturers began to introduce STM production lines, including Panasonic, Sanyo, Tesco, TDK, etc
On the contrary, Europe and the United States, which formed the earliest Surface Mount Technology, have made slow progress Japan, lacking resources but good at learning from the West and reinventing technology, accelerated the pace of development and application in the mid-1970s At the end of the 1970s, a large Japanese electronics enterprise group took the lead in successfully developing an automatIC chip mounter, which gradually improved from internal special equipment to commercial general equipment and was widely used in the production of household electronic products In the early 1980s, 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 developed vigorously in the development and competition of developed national large electronic group companies Since SMC/SMD has no lead or short lead, which improves the high-frequency efficiency of electronic products. In conclusion, it is the earliest and most commonly used color TV electronic tuner, with large volume and wide range 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 on September, 1973, Tamura Tamura was founded on November 21, 1973, and 1939. It can be seen that around the 1970s, some famous 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 into a well-known brand, while China's SMT has grown from scratch, from small to large, and has become the largest SMT application country in the world. 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 series of complete welding station models, continuously improved heating cores, and mainly anti-static products, 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 continuously introduces more and more perfect surface mount technology to enrich its domestic technology from abroad and improve the quality of its various electronic products This is the general trend and there is no doubt about it
