TMM4 High Frequency Printed Circuit Board 60mil 1.524mm Rogers RF PCB DK4.5 With Immersion Gold
(PCB's are custom-made products, the picture and parameters shown are just for reference)
General Description
This is a type of double layer RF PCB which is made on Rogers TMM4 60mil substrate. There’s only 1 NPTH hole in the board with 0.5oz base copper plated to 1oz. The surface finish on pads is immersion gold and no solder mask or silkscreen printed. Track layer is on top and whole bottom layer is copper covered as shielding function. The boards are fabricated as per IPC Class II standard and 100% electrical tested before shipment. Every 25 board are vacuum packed for delivery.
