The development history of electronic components is actually a condensed history of electronic development. Electronic technology is an emerging technology developed at the end of the 19th century and the beginning of the 20th century. It has developed most rapidly and widely used in the 20th century, and has become an important symbol of the development of modern science and technology.

When designing a four layer PCB circuit board, how to design the stack? Theoretically, there can be three schemes

A semiconductor is a substance with a conductivity between that of a conductor and an insulator. It is not very conductive in a pure state, but its conductivity can be adjusted by adding impurities (doping) or changing the temperature. The typical representative of semiconductors is silicon, which is widely used in the manufacturing of electronic components. Semiconductor technology is the cornerstone of modern electronic devices, such as smartphones, computers, digital cameras, etc., all rely on semiconductor chips. In addition, semiconductors are also very important in the energy field, such as semiconductor materials, which are the core of solar cells

You’re likely to deal with integrated circuits in electronics design. Occasionally, you may face the herculean task of working with a microprocessor. It’s a mistake to assume that designing with a microprocessor is similar to typical ICs.

High Density Interconnection (HDI) PCB is a kind of (technology) for the production of printed circuit boards. It is a circuit board with relatively high circuit distribution density using micro blind via and buried via technology.

We all know that there are many procedures for making HDI PCB from the planned feeding to the final step. One of the processes is called browning. Some people may ask what is the role of browning?
