With the maturity of advanced laser drilling technology and plasma dry etching technology, it becomes possible to apply non-through small blind holes and small buried holes. If the diameter of these non-through vias is 0.3mm, the resulting The parasitic parameter variable is about 1/10 of the initial common sense hole, which increases the reliability of the PCB. Because it is deemed appropriate to use non-through via technology, there will be few large vias on the PCB, so more space can be provided for wiring. The remaining space can be used as a shielding field for large planes or object surfaces to improve EMI/RFI performance.

The high-frequency PCB circuit board is mainly a special kind of PCB circuit board with high electromagnetic frequency. Because its physical indicators, precision and technical parameters and other indicators have high requirements, it is necessary to pay careful attention to each one during production. Whether the various index parameters of the production link are within the normal range, it is widely used in satellite satellite systems, radio systems and vehicle collision prevention...

Digital components are moving in the direction of high speed, low power consumption, small size, and high anti-interference. This development direction puts forward many new requirements for the preset of printed circuit boards. Based on years of experience in the hardware preset office, the author summarizes a few high-frequency wiring techniques for your reference.

1. The impedance control concept is introduced to distinguish the resistance of direct current (DC). The resistance encountered by alternating current is called impedance (Z0), including resistance (R), inductive reactance (XC) and capacitive reactance (XL). Special impedance is also called "special impedance". Refers to the transmission signal line at a certain frequency (that is, the copper wire of the circuit board we manufacture)

In recent years, the PCB circuit board industry has become a world-wide industry. There are more than 2,800 printed circuit board companies in the world, with an output value of more than 50 billion US dollars, accounting for more than 1/4 of the total output value of the electronic component industry. The industry with the largest proportion of the various electronic component sub-industries, and the proportion is rising rapidly, is the main pillar of the future progress of the electronic component industry. However, due to the outbreak of the international financial crisis in 2008 and the European debt crisis in 2012, the world's PCB multilayer circuit board industry has passed a difficult period of time. With the rise of electronic terminal industries such as shouji, tablet computers, and green base stations , The world’s PCB multilayer circuit board industry will further shift its focus to Asia. We will usher in a new opportunity for progress. However, due to the advantages of cost and market, the domestic PCB multilayer circuit board companies will face In the face of more miserable market competition, where should we seize opportunities to become bigger and stronger in the fierce struggle for survival?

The demand for the production of small and medium-sized HDI circuit boards in Beijing will require metal to be plated on the edge connector, the edge tapping point or the golden finger to provide lower connection resistance and higher wear resistance. This technology is called finger row Electroplating or partial electroplating.
