Rigid-flex board is a combination of flexible board and hard board. It is a circuit board formed by combining a thin layered flexible bottom layer with a rigid bottom layer, and then laminating it into a single component.The flexible board is used to replace the cable assembly to complete the highly reliable connection and transmission of power and electrical signals.The product can work stably and reliably for a long time under harsh environments such as high and low temperature, high humidity, vibration, salt spray, and low air pressure. At present, Jonhon Optronic has provided rigid and flexible printed board solutions for aviation, aerospace, ships, weapons and other fields.

Beginners may be confused by the terms "chip" and "semiconductor" and cannot distinguish their relationship. Today, Hongtai Express Electronics will focus on sorting out the connections and differences between chips and semiconductors that we often talk about.

At present, most of the holes drilled in the double-sided flexible printed board are still drilled by the NC drilling machine. The NC drilling machine is basically the same as that used in the rigid printed board, but the drilling conditions are different. Because the flexible printed board is very thin, multiple pieces can be overlapped for drilling. If the drilling conditions are good, 10 ~ 15 pieces can be overlapped for drilling.

What is the status of Chinese chips On June 9, 2021, at the world semiconductor conference, Wu Hanming, an academician of the Chinese Academy of engineering, pointed out the current situation of China's chips: China still needs 8 SMIC's if it wants to complete the localization and replacement of chips. In short, now China needs 8 SMIC's

Substances and materials in nature can be divided into three categories: conductors, semiconductors and insulators according to their conductivity. The resistivity of semiconductor is in the range of 1m Ω· cm ~ 1g Ω· cm (the upper limit is taken according to Xie jiakui's electronic circuit, and 1/10 or 10 times of it; because the angle mark is not available, the current description is used temporarily)

On April 24, Han's Laser released its 2016 annual report and a quarterly report for 2017. During the reporting period, it achieved operating income of 6.959 billion yuan, a year-on-year increase of 24.55%, and realized net profit of 754 million yuan. In 17Q1, profit increased by 31.50%, and the profit growth rate in the first half of the year is expected to be 60%-90%.
