RO4830 High-Frequency PCB: 9.4mil Substrate with Double-Sided Copper and Immersion Gold
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Brief Introduction
The RO4830 high-frequency PCB features a 2-layer rigid design consisting of copper_layer_1 (35 μm), a Rogers RO4830 core (9.4 mil or 0.239 mm), and copper_layer_2 (35 μm). This PCB is constructed with specific details to meet diverse requirements.
The board dimensions measure 75.15mm x 43.8mm, with a tolerance of +/- 0.15mm. The minimum trace/space is set at 5/6 mils, allowing for precise routing and spacing. The minimum hole size is 0.35mm, compatible with standard drill sizes. The finished board thickness is 0.3mm, ensuring a compact form factor. The outer layers feature a finished copper weight of 1oz (1.4 mils), with a via plating thickness of 20 μm to ensure reliable electrical connections. The surface finish is immersion gold, providing excellent solderability and corrosion resistance.
This PCB does not include top or bottom silkscreen or solder masks. It undergoes a 100% electrical test prior to shipment, ensuring the quality and reliability of circuit connections.
In total, the PCB includes 10 components, 16 pads (12 through-hole pads and 4 top SMT pads), and 140 vias with 4 nets representing unique electrical connections.
The manufacturing artwork is provided in Gerber RS-274-X format, a standard accepted in the industry. The fabrication quality adheres to IPC-Class-2 standards, ensuring compliance with specific workmanship and performance criteria.
This PCB is available for global distribution, allowing customers from various regions to access its features and specifications.
