A brief history of the development of SMT patch proofing technology
SMT patch proofingTechnology is developed from the manufacturing technology of component circuits. From the 1970s to the present, the development of this technology has gone through the following three stages:
The first stage (1970-1975): The main technical goal is to apply miniaturized chip components to the production of hybrid circuits (called thick film circuits in my country). From this perspective, SMT patch proofing technology It has made significant contributions to the development of integrated circuit manufacturing process and technology; at the same time, SMT patch proofing technology has begun to be widely used in civilian quartz electronic watches and electronic calculators.
The second stage (1976-1985): to promote the rapid miniaturization and multi-function of electronic products, and they began to be widely used in products such as video cameras, earphone radios and electronic cameras; at the same time, a large number of automated equipment for surface assembly was developed and developed , The assembly process and support materials of the chip components have also matured, laying the foundation for the rapid development of SM patch proofing technology.
The third stage (1986 to present): The main goal is to reduce costs and further improve the performance-price ratio of electronic products. With the maturity of SMT patch proofing technology and the improvement of process reliability, electronic products used in military and investment (automobiles, computers, industrial equipment) fields have developed rapidly. At the same time, a large number of automated surface assembly equipment and process methods have emerged. The rapid increase in the use of chip components on PCBs has accelerated the decline in the total cost of electronic products.
One of the important foundations of SMT patch proofing technology is surface mount components, and its development needs and development level are mainly restricted by the development level of surface mount components SMC/SMD. For this reason, the development history of SMT patch proofing technology is basically synchronized with the development history of SMC/SMD.
