I have read in some magazine articles that there is poor signal to noise ratio of RF devices when no-cean solder is used. The frequecies used exceed one Mhz? Is this true?

Some under-the-hood automotive people have moved from no-clean to clean, and I mean CLEAN, recently. Hmmmm Dave F

Hi Jeff Actually it's not necessarily Signal to Noise Ratio or even RF circuitry. All no cleans leave behind residue by description. This residue can affect RF or other high frequency circuits in a number of different ways including SNR. Very high

Now an than I hear, read about the same thing but without mentioning specific frequencies. It�s something that worries me in the back of my mind but not in actual daily workflow. Our boards go up to 50Mhz with digital bus systems and are made with no

Anyone using a No-clean solder paste on a pcb with a 100 Mbps Ethernet chip? Will the residue cause any signal degradation? Any issues with a no-clean solder paste and 1000 Mbps Gigabit Ethernet? Device: National Semiconductor DP83848 10/100 Mb

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.

We have a name brand aqueous batch cleaner that uses a chemical and DI water to clean ROL0 flux from our PCBs. It does ok most of the time for SMT boards and we want to include through hole assemblies as well which should be a better cleaning process

A water soluble solder paste (AIM WS483), reflow and wash. We are considering using AIM NC254 No-clean solder paste to eliminate the wash step.

I would think if the product can take wash, it could take no-clean. Unless it has sensitive devices susceptible to leakage.

We built tens of thousands of boards with transeivers on them with a no clean process.Never had any problems with the flux residue in relationship to board performance.
