2-layer TLX-7 RF PCB 20mil Immersion Silver 0


This PCB constructed with TLX-7 follows a 2-layer rigid design, featuring copper layers with a thickness of 35 μm on both sides and a Taconic TLX-7 core with a thickness of 0.508 mm (20mil). The board dimensions are precisely measured at 91mm x 75mm, with a tolerance of +/- 0.15mm. The minimum trace/space is 4/5 mils, and the minimum hole size is 0.3mm. The finished board thickness is 0.6mm, with a 1oz (1.4 mils) outer layer copper weight. Via plating thickness is 20 μm, and the surface finish is immersion silver. There is no top or bottom silkscreen or solder mask applied. Each PCB undergoes a 100% electrical test before shipment to ensure its quality and functionality.


TLX-7 PCBs have been designed to meet IPC-Class-2 quality standards. They are available worldwide, making them accessible for various projects and applications. With their exceptional properties, TLX-7 PCBs find applications in radar systems, mobile communications, microwave test equipment, microwave transmission devices, and components such as couplers, splitters, combiners, amplifiers, and antennas.


Experience unparalleled reliability, outstanding performance, and seamless integration with TLX-7 PCBs, the perfect choice for your RF applications.
