Hello John, There are some coatings for aluminum to eliminate solder drag out. The do not work with all fluxes it is called hardcoat anodized it is black or geen in color. Unless you have faily high volumn the hard coat cost can be as high as titan

As I am certain you have discovered, no clean solder paste has removed most inline cleaners from the production floor and the pallets that were cleaned simultaneously with the PCBs are now accumulating flux residue. Permali, the maker of Durostone

Hi Jason I think Wolfgang has this one nailed. If it's the same four pins every time and nothing changes this, even rotating the board 90 degrees, then you're probably going to find something like a ground plane connected to them. I don't think sol

Yea you gotta love those airknives. It may not work in this application if the shorts are present at the trailing edge. I have several boards that are using conns with pins at .050" centers and they short. The protrusion is .030" to .040". The shorte

Superflo 26F is a no-clean flux, I bet your trying to wash it in water. You could not clean the board that flux will not hurt it at all, that is unless your conformal coating it. You could also run a simi-aqueous wash or maybe a saponifier in your wa

Thanks for all the ideas. I tried solder "thieves" by placing some desoldering wick behind the briging pins and it worked! I have yet to try Chrys' idea but I will first thing Monday. This is a new board that has had this problem from day one. I

Am I missing something here? I usually put some type of stiffener or support on the leading edge to make sure the PWB doesn't sag in the middle from the preheat. If I had to add a bean bag with shotgun pellets or BB's I would have boards falling out
