Sorry for the delay. We are actually pretty busy over here. We have found the Aim 257-2 no-clean sac305 paste offers very little if any voiding and better wetting in lead free terminated devices. My suggestion is contact your local Aim distributor fo

Its SAC305 paste. Will that corrode the tip or the tin alloy?

Yes, we are looking at using it for our solder paste. The customer mentioned wants us to test our boards and initially we've heard the SAC105 is better for "higher mechanical stressed" assemblies. Thanks for your reply!!

Are you using a SAC305 or high tin alloy? That will corrode the solder tip as well. Chris

I can't answer for wave, but we tried some Sn100 paste for reflow, and couldn't get it to work worth a darn. I then got some SAC305, and was relieved to see it work almost as well as SnPb at its best! Much better wetting and flowing to the various

We are not using SN100C in our reflow process but I know the type of flux made a big difference with our SAC305 solder. We started out using no-clean flux in our SAC305 paste and were having some issues. We then switched over to a water soluble flu

Anyone have any advise on reduing voiding in BGAs using a SAC305 solder paste?

You're using a SAC305 chemistry? Double check your liquidus temp! Your profile shows a liquidus temp of 217 degrees C. SAC305 is not eutectic. (It doesn't transition from paste to liquid instantly). It goes thru a "pasty" stage. We use a temp of 221
