TMM4 High Frequency Printed Circuit Board 60mil 1.524mm Rogers RF PCB DK4.5 with Immersion Gold
(Printed Circuit Boards are custom-made products; the images and specifications shown are for reference only.)
TMM4 High-Frequency Printed Circuit Board Overview
General Description
This double-layer RF PCB is constructed on a 60 mil Rogers TMM4 substrate with a dielectric constant of 4.5. The board features one non-plated through-hole (NPTH) and is designed with a base copper weight of 0.5 oz, plated to 1 oz. The surface finish on the pads is immersion gold, and there is no solder mask or silkscreen printed. The top layer contains the track, while the entire bottom layer serves as copper shielding. All boards are fabricated according to IPC Class II standards and undergo 100% electrical testing before shipment. Every 25 boards are vacuum packed for delivery.
