Posting here because all the threads asking for feedback on it are locked. We have been extremely happy with the 4300 tacky flux for BGA attachment. Not only is it both washable and no-clean (i.e. wash-optional), it was also the only tacky flux tha

Any decent flux would volatise off with the heat of the wave unless absorbed into the solder mask. Test this by trying to clean in alcohol or common solvent aerosol, if it does not clean then it is probably Mineral Salts from solder mask fillers. Ano

IMHO I would suggest that if you are using flux only during a BGA placement on a small run, that you first tin the pads with your soldering iron, then level the pads back out with wick. Accomplishes two things; adds a little metal to the joint to ma

Hi, If your using NXT to place these BGA's then you must be doing large runs. BGA's are the most easy part to place, and don't worry about them. Just stencil paste down for them as any other component. But we use 1:1 reduction on our stencil, so we

We are in the process of changing over our wave solder flux from alcohol based no clean to VOC free water based no clean. We are running an old Eletrovert with foam fluxer, tin lead solder. After preliminary testing on scrap boards and now starting t

C.K. I would like to receive the paper that you wrote, I am in process of implementing VOC free at our factory and could use all of the information that I can get. Thanks Russ

Yes, no-clean is more of a challenge, particularly for halide-free no-clean. Requirement on probe testability will make it more difficult.

Ummm...Ok? Lumidor, The best thing to do is find out at which process this "wax" is occurring at. Targeting the process that just changed may be presumptuous on your part. Pick up the phone or make a visit. In either case, you're the customer a

Just curious� Why only localized cleaning? Why not clean the entire board? Localized cleaning by nature is labor intensive. Mike Konrad Aqueous Technologies (909) 944-7771 ext 29 www.aqueoustech.com konrad@aqueoustech.com
