I run two different waves here one with SAC305 with aqueous flux the other with SN100C and No clean flux. Does anyone see any issues with running product through either machine of course after changing the Flux type? I also only use SAC305 alloy for

I'm looking for a No Clean low or an ultra low flux residue solderpaste (SAC305 and Sn/Pb). Any Recommendation? Is there something in the datasheet that will tell if a solder paste is really a low residues flux. Also is there a method to clean the

Are the tin/lead ratios compatible betweem HASL and wave solder? Probably are, just a remote possibility. Flux application is? bubbler, sprayer? Either way, are you getting good misting, coverage on those teeny 0.5mm test points? If not, then no

Dear Tom : I hope I �m not too late. We produce PC motherboards with some buses exceeding the speed of 100MHz . we use no clean flux and it is OK even with the residues you can see under a microscope. But according to our own experience through a mo

Hello everyone. Can someone please tell me if there are problems using No Clean solder for SMT and then using WS Flux with our Wave process? We are aquaeous cleaning after...but are there other cross-contamination issues? THANKS!!!

My company is currently looking for a closed loop system that we could use for batch washing of PCBs. We primary use no clean flux and are looking for a system that we can use to clean the residue? Most likely we are going to have to add an additiv

Reflowing a BGA can be a reliable and long term fix, but it has to be done correclty, and using a heat gun and going in circles around the part is definitly not the right way to do it. To do it correctly you would flux under the bga, use a rework st

Hi. We are currently using an unconventional method to rework a micro BGA - removing component with hot air, fluxing the area, placing the part with pick and place, then reflowing it in the oven. The reason we are doing it this way and not with a r

We are interested in hooking up a batch acqueous cleaning system in CHICAGOLAND area (for cleaning RMA flux). Can somebody recommend an EPA contact? What type of regulatory requiremetns would there be? What agency should we seek out before we instal

First Time to solder BGA's using Water Soluble. We are currently using an Aquaeous Cleaner to clean our PCB's but I find it not enough to clean the flux from under our BGA's. Has anyone had this experience before that he may like to share how he mana
