SMT patch processing development status in China
SMT: Historically speaking, SMC/SMD, a mounting component, was invented in the mid-1960s by European and American advanced technology countries. On the ceramic substrate where lines, thick film resistors and pads have been made previously, solder paste is printed and hand-pasted with leadless monolithic ceramic capacitor MLC, a short pin transistor called "sesame tube" and a mount IC, and then flow welded to complete the assembly. This is the prototype SMT mode. Although the term "SMT" had not yet emerged, nor had it yet formed a separate technical category, the emerging advanced assembly process had shown itself to have great vitality.https://www.kingfordpcb.com/yuan.php
In the early 1980s, Chinese electronic component academia had paid close attention to the development trend of SMC/SMT in the world. From the late 1970s and early 1980s, Chinese electronic technicians began to track the development of SMT patch processing technology in foreign countries, and applied STM technology in a small range. The earliest large-scale introduction of STM production lines in China began in the early and middle 1980s. Its background is the introduction of color TV industry technology in China. For its matching color TV tuner, such as Panasonic color TV tuner from type A to type B electronic tuner, and the new tuner 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, the models introduced are Panasonic, Sanyo, TESCON, TDK, etc.
On the other hand, Europe and the United States, where SMT technology was first formed, made slow progress, while Japan, lacking resources but good at learning from the West and innovating technology, accelerated the pace of development and application in the mid-1970s. In the late 1970s, Japan's large electronic enterprise group took the lead in developing and successfully developing automatic SMT mounters, which gradually improved from internal special equipment to commercial general equipment, and were 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 of the key process equipment of automatic SMT. SMT chip processing technology in the developed countries among large electronics groups focus on development and competition has been a vigorous development. Because SMC/SMD has no lead or short lead, it is convenient to improve the high frequency performance of electronic products, so it is used in the earliest and most wide range of color TV electronic tuner. It was in this context that a large number of SMT related enterprises emerged in Japan in the 1970s. GOOT Taiyang Electric was established on April 30, 1965, September 1973
MALCOM was founded on 21 November 1939 in TAMURA. It can be seen that some well-known SMT related enterprises in Japan were established in the 1970s. After more than 20 years of development, SMT technology has become increasingly mature and high-end. Those initially established Japanese enterprises have grown into well-known brands, while SMT in China has grown from scratch and from small to large, and has become the largest SMT application country in the world. The popularization of SMT SMT processing has made a great contribution to the development of electronic information industry in our country.
Looking ahead, TAMURA's lead-free solder paste has been gradually replaced by leaded solder paste, and low silver solder paste has been developed to fill the automotive electronics gap; A variety of MALCOM SMT peripheral testing equipment is continuously developed and improved, from simulated reflux to real-time through furnace monitoring. GOOT all kinds of welding table models, heating core is constantly improved, anti-static products dominate in line with the trend. All these signals indicate that SMT technology abroad is becoming more and more mature, environmentally friendly and advanced.
With the rapid development of communication, computer, network and electronic products, and according to the national requirements for the development of strategic emerging industries, SMT processing also has a broad development prospect in our country. As the world's largest and most important STM market, China also has a huge demand market for SMT related products. Therefore, it is a general trend for China to continuously introduce increasingly perfect SMT technology from abroad to enrich its own technology and improve the quality of various electronic products.
