Microwave Tech - High frequency circuit board first iPCB

With the rapid development of electronic information technology and the widespread use of wireless communication technology in various industries, high frequency, high speed, and high density have gradually become one of the important development trends of contemporary electronic products. The signal transmission power of high-frequency and high-speed digitization makes the PCB transition to microvias and buried/blind vias, fine lines, and thin dielectric layers. High-frequency, high-speed, high-precision multi-layer PCB circuit board design technology has become a very critical research field in today's development era.
A High-frequency circuit board is a special circuit board with high electromagnetic frequency. Generally speaking, a high-frequency board can be defined as a frequency above 1GHz. Its physical performance, precision, and technical parameter standards are very high, and it is often used in automobile anti-collision systems, communication satellite systems, wireless communication systems, and other industries.

The high-frequency PCB circuit board provided by the utility model is provided with ribs on the upper and lower opening edges of the hollow groove of the score board. In this way, when the core board is bonded with the copper-clad laminates placed on the upper and lower surfaces, the glue flow will not enter the hollow groove, that is, the bonding operation can be completed by one pressing. Compared with the previous circuit board, the circuit board of the present invention needs to be pressed twice and then cooperated with the current technology to complete the production of the high-frequency circuit board. The mechanism of the new high-frequency circuit board is relatively simple. Moreover, the cost is lower, and it is easier to manufacture.
