High frequency application V.S no clean flux| 8 July, 2002
How can I find the technical paper or source of information about using No-clean flux with high frequency apllication. High frequency mean more than 2 GHz - 5 GHz. I heard from my colleague that No-clean flux residue on board effect to high frequency application. I have ask some solder paste supplier but they ask no study report about 5 GHz frequency application.
Somebody souces told that solid content left on board should not exceed 2 %. How can know and check solid percent of solid content.
Anybody have experience on this issue please help advice me.
