Technical advantages of PCB boards for high-frequency communications

With the rapid development of 5G technology, the demand for high-frequency PCB boards in the communications industry continues to rise. With years of industry experience, Mingzhenghong Electronics Co., Ltd. specializes in providing high-frequency communication-specific PCB boards for Huawei and ZTE 5G base stations, using advanced ROGERS materials such as RO4003, 4350, 5880, etc. to ensure excellent signal transmission quality.

Core materials and design structure

Our PCB board is designed as a 6-layer structure, with a combination of ROGERS 4003 and FR-4 TG170 (IT-180A) used inside. This design can effectively enhance the signal level and comprehensively improve the stability and integrity of signal transmission.

The specific technical parameters are as follows:

• The outer copper foil and the inner copper foil are both 35 microns.
• The minimum drilling diameter is 0.25mm, and the minimum line width/line spacing reaches 4mil (0.1mm).
• The board thickness is 1.6mm, the PCB is 200mm long and 105mm wide, with an aperture ratio of 6.4:1.

Environmental and certification standards

Our products comply with 94V0 RoHS standards and have passed CE, RoHS, UL, SGS, ISO9001 and other international certifications to ensure environmental protection and safety performance. In addition, the ENIG process is used to provide a 3u" gold layer thickness to ensure good welding performance and long-term oxidation resistance.

Wide range of applications

This series of high-frequency PCB boards are not only suitable for communication base stations, but also widely used in high-speed data transmission fields such as data centers, wireless routers and switches. Due to its high temperature stability and good electromagnetic compatibility, it is also an ideal choice for high-precision fields such as aerospace, military communications and medical equipment.

Summarize

Mingzhenghong Electronics Co., Ltd. uses advanced LDI equipment and has an annual production capacity of more than 500,000 high-frequency communication PCB boards. We are committed to ensuring that every PCB board can provide customers with the best service in terms of technology and quality.
