No-clean flux and high freq. applications? | 5 February, 2007

Good morning,

What is considered "high frequency" ,.i.e. Mhz,GHz,etc., when we talk about possible issues with NO-clean flux residues and product's application?

I appreciate your help on this...

Have a good one! George

I had problems with very simple timing circuits in the kilohertz range with leadfree NC solder pastes. Never saw the problem with lead NC solder paste. Run lead free no clean and clock was off. Run lead no clean and clock was right on.

I have a customer who runs A-D applications with 5GHz analog and it is 100% no clean.

The only answer that will be acceptable is what works for your circuit design.
