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.

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

Just to add a comment, we were using AIM Lead Free (SAC 305/ NC254 & 257) in the past and we had Voiding problems, then we tried Indium 8.9 HF, and we have better results, so now we are evaluating change to Indium for many of our products.

I just need a clarification on NC254 No clean solder paste. If we have parts on the bottom side of the board that already are soldered and we go to run the other side of the board and it was misprinted, is it ok to run thru the washer? I just need

how many layer board is it? what kinda temperatures is your oven currently hitting. In our reflow oven I have been using a profile that is the same for the top and bottom at zone 1 111C zone 2 at 164C zone 3 at 161C zone 4 at 208C and zone 5 at 2

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.
