What should be paid attention to in the anti-corrosion treatment of multilayer circuit boards

Chips are large-scale, microelectronic integrated circuits. That is, the printed circuit board is scaled down to nanometer (one millionth of a millimeter). On the front of the traditional printed circuit board, there are a large number of radio components, including triodes, diodes, capacitors, electrolysers, resistors, mid cycle regulators, switches, power amplifiers, detectors, filters, and so on.

Printed circuit board (PCB), also known as printed circuit board, is the supplier of electrical connection of electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit board is that it greatly reduces the wiring and assembly errors, and improves the automation level and production labor rate. According to the number of circuit board layers, it can be divided into single board, double board, four board, six board and other multilayer circuit boards.

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:

HDI in HDI Board is the abbreviation of High Density Interconnector. It is a kind of (technology) for producing printed circuit boards. It uses micro-blind and buried via technology for a circuit board with a relatively high line distribution density. HDI is a compact product designed for small-capacity users.

The semiconductor industry is a high-tech industry that involves the research and development, manufacturing, and application of semiconductor materials. Semiconductors are a special type of material with conductive properties that lie between conductors and insulators. Semiconductor materials achieve the functionality of electronic devices by controlling the flow of current.
