Mingzhenghong Electronics Co., Ltd. specializes in providing high-frequency PCB boards for Huawei/ZTE 5G base stations. The products use ROGERS materials such as RO4003, 4350, 5880, etc., as well as other brand materials such as POLYIMIDE, TACONIC, PANASONIC, etc., to meet the needs of different customers and application fields. need. The PCB board is designed as a 6-layer structure, using a combination of ROGERS 4003 and FR-4 TG170 (IT-180A) materials. ROGERS 4003 is used for L1-L2/L5-L6 in the stack, and FR-4 TG170 is used for other layers to ensure the protection of high-frequency signals. Integrity and stability. The outer copper foil and 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. The surface treatment adopts the immersion gold process (ENIG), and the thickness of the gold layer is 3u". The product complies with the 94V0 RoHS standard, has passed CE, RoHS, UL, SGS, ISO9001 and other certifications, supports impedance control requirements, and is equipped with red solder resist paint and white Silk screen.
