RO4350B Laminates and Immersion Silver Surface Finish: A Winning Combination for PCBs

The newly shipped PCB is a high-performance electronic component that offers exceptional electrical performance and thermal stability. It has been designed specifically to meet the requirements of modern electronic devices that demand advanced technology. The PCB is constructed using RO4350B hydrocarbon ceramic laminates and a lead-free process, allowing it to operate efficiently in a temperature range of -40℃ to +85℃, making it suitable for use in various applications.

The PCB is a 2-layer rigid PCB, with a finished copper weight of 35um on both sides and a RO4350B dielectric thickness of 20mil. This construction ensures efficient signal transfer, reducing signal loss and cross-talk. The board dimensions are 122mm x 74mm, with a tolerance of +/- 0.15mm. The minimum trace/space is 7/9 mils, and the minimum hole size is 0.3mm. No blind or buried vias are present, and the finished board thickness is 0.83mm.

The finished copper weight of all layers is 1 oz (1.4 mils), and the via plating thickness is 1 mil. To provide a flat and smooth surface for soldering, the PCB has immersion silver as its surface finish. There are no top or bottom silkscreen or solder mask, and no silkscreen on solder pads. The via is filled with copper paste for better heat dissipation, ensuring thermal stability. The PCB is 100% electrically tested, ensuring it meets high-quality standards.

The PCB boasts 74 components, with a total of 109 pads, including 46 through-hole pads, 63 top SMT pads, and 0 bottom SMT pads. The PCB has 54 vias and 9 nets. The type of artwork supplied for this PCB is Gerber RS-274-X, a standard format for PCB design data.

The RO4350B hydrocarbon ceramic laminates used in the construction of the PCB offer excellent electrical performance and thermal stability. The laminates have low dielectric loss and high thermal conductivity, making them suitable for high-performance electronic devices. The lead-free process used in the production of the PCB makes it more environmentally friendly, reducing its impact on the environment.

The finished copper weight of all layers and the via plating thickness ensure that the PCB provides reliable electrical connections and efficient signal transfer. The immersion silver surface finish provides a flat and smooth surface for soldering, making it easy to assemble the PCB onto electronic devices. The via filled with copper paste ensures better heat dissipation, improving the thermal stability of the PCB.

In conclusion, the newly shipped PCB is a high-quality product that is designed to provide efficient signal transfer, reliable electrical connections, and easy soldering. Its laminated substrate ensures excellent electrical performance and thermal stability, making it suitable for high-performance electronic devices. The lead-free process used in production makes it environmentally friendly, reducing its impact on the environment. The PCB is constructed to the highest quality standards and undergoes 100% electrical testing. For any technical questions, Sally Mao at sales30@bichengpcb.com can be contacted.
