With the continuous development of modern technology, the replacement cycle for all kinds of electronic products continue to shorten, which greatly reflects the great charm of scientific and technological development. Development of the modern electronics industry, mainly reflects in the integration of electronic components is getting higher and higher, the volume occupied is getting smaller and smaller, and it also has the trend of using the bga type packaging. Due to the specific technical requirements, some related to the PCB line production must be getting smaller and smaller, and there are more and more levels, and it also has to reduce the line width distance to make full use of the limited area, this is not difficult to see that smaller high-precision custom pcb board will become the mainstream in the near future.
Environmental PCB Design Become a Trend
It is worth emphasizing that, with the people's awareness of environmental protection, PCB manufacturers conform to the mainstream, to pay attention to the environmental protection of the PCB production. Their decision-making is worthy of recognition, after all, the present environment, environmental protection requirements is increasingly high, companies do not pay attention to environmental protection, not to do something on technological improvements, the end result is that they will not survive in this industry. This is not alarmist. According to the investigation that of mainland China PCB industry cluster formation of the Pearl River Delta and Yangtze River Delta region. Such a high-density clusters, making the relevant government departments to take a restrictive legal measures, the introduction of the decree. PCB manufacturer is undoubtedly a blow to many manufacturers in order to survive, had to early to find alternative production base, which is quite upset. Therefore, in the future, in order to survive or be creative and the pursuit of scientific and technological progress,the enterprise should be committed to exist with the environment in a harmony way.
Classification of Flexible Circuit Boards
According to the combination of substrate and copper foil,flexible pcb board can be divided into two types: plastic flexible pcb board and non-plastic flexible pcb board. And the non-plastic flexible board price is much higher than the plastic flexible board, and its flexibility, the binding capacity of the copper foil and the substrate pad flatness parameter is better than the plastic flexible pcb board. Therefore, it is generally used only for those high demanding occasions, such as: COF (CHIP ON FLEX, flexible on-board mounting bare chips, demanding flatness of the pad). Its applications are currently plastic pcb board on the market because its price is too high. Since flexible pcb board is mainly used for bending occasion, if the design or process is irrational, it is prone to micro-cracks and open welding defects.
