i'm new to pcb design and i'm wondering that starting from which frequency range we need to apply the high speed PCB design rules and techniques ?

I think it is normally from 4.0 to 5.0

Here is a video for high speed pcb design rule and techniques. https://www.youtube.com/watch?v=BlHLmQ2HO1w This may help you.

can you send me the articles about the high frequency boards issues with different types of solder paste alloy because i can`t find any free document about this article

Does it fail to function or does it function outside of acceptable tolerances? If the latter I wouldn't know what to think, but if the former I would feel obligated to suspect solder quality or maybe even a component problem with the elevated lead-

Lots of papers out there on HiFreq circuits and the effects of solder paste residue. Google Dr. Karen Tellefsen. Simple test...take a "failed" board, remove the residues, test again. Has the problem gone away?

everything else EXACTLY the same? meaning exact same product number from the same manufacturer same fluxes used in the paste? no additional no clean "touchup" or hand soldering operations? No expert by any means but it would seem odd to me that the

I have always understood that on boards (or circuits) operating over 900 MHz, No Clean fluxes are to be avoided. Apparently the residues left behind, while non-conductive and non-corrosive, will change impedence of the circuit. It may be a possibil
