PCB stack-up question for 4 layers PCB
I want design a 4-layered PCB. There is one way of stack-up I learned by searching online: TOP--GND--VCC--BOTTOM But waht I want is as below: TOP--VCC--BOT--GND Will there be a problem?
The operating frequenncy and the application of your design is not given by you. So that it is impossible to give clear advice.
Generally speaking,Altium is not a good PCB package for RF circuits with the need of Transmission Lines,Microwave Elements such as Lange Couplers, Sheet Filters etc. Cadence Allegro+RF Option is a good choice for these types of layouts but it's quite expensive.
Is there a RF design or a high speed digital design you need? And what is the function of this design.Onlu when you write clear about your question,we can answer clear.
Not the answer you're looking for?
