This PCB stackup comprises two copper layers with a thickness of 35 μm each, separated by a 1.00 mm F4BM220 core. The board dimensions are precisely set at 45mm x 62mm with a tolerance of ±0.15mm, suitable for various compact applications. The minimum trace/spacing requirements are 4/7 mils, with a minimum hole size of 0.3mm, facilitating intricate circuit designs.
A finished board thickness of 1.1mm, a copper weight of 1oz (1.4 mils) on outer layers, and a 20 μm via plating thickness contribute to this PCB's robust construction. The surface finish is achieved with immersion tin, while the top solder mask is green, and the top silkscreen is white. Prior to shipment, each PCB undergoes 100% electrical testing to ensure quality and reliability.
Supplied in Gerber RS-274-X format and adhering to IPC-Class-2 quality standards, the F4BM220 2-layer rigid PCB is available worldwide.
Typical Applications:
Microwave, RF, and radar systems
Phase shifters
Power dividers, couplers, combiners
Feed networks
Phase-sensitive antennas, phased array antennas
Satellite communications
