EM-888 Rigid-Flex PCB Manufacturers

Semiconductors have a wide range of applications, almost permeating every aspect of our lives. It is widely used in fields such as electronic products, communication equipment, computers, medical equipment, etc. According to different application fields, semiconductors can be divided into six major sub sectors:

PCB proofing, as a component of high-precision electronic products, has been a very common existence in life. However, we all know that domestic professional PCB proofing design needs different point settings in different stages, and large grid points will be used for device layout in the layout stage. Let's take a look at the detailed PCB proofing layout setting skills.

There are many forms of matter, such as solid, liquid, gas, plasma and so on. We usually call materials with poor conductivity, such as coal, artificial crystal, amber, ceramics and so on, insulators. Metals with good conductivity, such as gold, silver, copper, iron, tin and aluminum, are called conductors. The material between conductor and insulator can be simply called semiconductor. Compared with conductors and insulators, the discovery of semiconductor materials is the latest. Until the 1930s, when the purification technology of materials was improved, the existence of semiconductors was really recognized by the academic community.

RF PCB, means radio frequency PCB. People also called these PCB High frequency PCB, it is for the PCB with a higher electromagnetic frequency, and it is used on the products field with high frequency. (Frequency greater than 300MHZ or wavelength less than 1 meter) and microwave (frequency greater than 3GHZ or wavelength less than 0.1 meter). It is made by microwave substrate with common PCB manufacturing process or with some special way to make.

The concept of integrated circuits traces its roots back to the late 1950s and early 1960s. Jack Kilby, an engineer at Texas Instruments, and Robert Noyce, co-founder of Fairchild Semiconductor and later Intel, independently conceived the idea of integrating multiple electronic components onto a single semiconductor substrate.

Photoelectric boards refer to PCBs used for LCD and other purposes, and have very strict requirements on size.
