Not in this case, these BGAs were lead free and the profile used was for a lead part. I guess I will give you the whole story. These boards were sent to us from a customer to have the BGAs replaced for an unknown to us reason. We removed the parts

Hi, I am having a SAC 305 solder paste with water soluble flux wetting issue. during reflow, the solder melts, but doesnt flow. the reflow profile was developed by the solder company person (Kester). the board is a test assembly to validate our LF pr

Oops...just noticed you were referring to wave soldering. We'd still suggest a water-soluble flux, instead of the no-clean; especially at wave soldering. Also, checking pre-heat temps, and dwell time on the pot. Is the wave a chipper wave? If not

*yes, I used water soluble solder paste (OMG-WS-300), the flux type is ORM0. The component terminations are bare copper,and they�re supposed to be that way. The supplier of these parts is MAXIM, produced from Philipine, get from customer. * We can no

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

Steve: I thought Kyzen products were "additives" to either aqueous or semiaqueous inline or batch machine cleaning processes. I'm trying to clean the no-clean residue from a few components that can not bear to see water. Can you use Kyzen products

Doesn't really look like no-clean to me...typically, no-clean encapsulates the solder joint after reflow, trapping any organics. This looks like plain-old water soluble flux, that cooked a bit too much in reflow. As you noted, it cleaned up with

All, I have a reoccurring issue with the Alpha-Metals WS601, water-soluble paste in that the size 20 nozzle of the auger-type dispenser on my Camalot Gemini II clogs up rather frequently. Every few hours we are having to go in and clear out the nozz

guys Using a well estrablished water soluble solder paste, but having problems with tack time. Data sheet recommend a couple of hours but we are seeing problems after about 15 minutes with 0402/0603 componenets bouncing off. The printer environment

The variance of useability of any of the pastes with a difference of 5% in your overall environment will probably not even be measurable in the difference of the paste be it RMA, Water Soluble, or No Clean. What is the printer you are using and is i
