Immersion gold UL 94 Multi Layer PCB RO4003C 32mil And RO4450F 12mil PP

4 Layer High Frequency PCB On 2 Cores of 32mil 0.813mm RO4003C and 12mil RO4450F for Ultrahigh Frequency Coupler

(Printed circuit boards are custom-made products, the picture and parameters shown are just for reference)

Today we talk about a type of 4 layer high frequency PCB. This PCB is built on 2 sheets of 0.813mm (32mil) RO4003C cores with 1 sheet RO4450F prepreg for the application of ultrahigh frequency coupler. Following is the stack-up.

In general, multilayer Rogers high frequency PCBs are made from all high frequency material inclusive of prepreg adhesive. As is known to all, there’re 6 cores in RO4003C family, i.e. 8mil (0.203mm) to 60mil (1.524mm).
