High frequency application V.S no clean flux | 8 July, 2002

Hi all

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.

Thks you all. Benny

Everyone has their stories, don't they?

Here is a method for evaluating the effect of nc flux res on high frequency circuits => http://www.goapex.org/html/S32-1_Csonka-Peeren.pdf
