Has anyone out there had solder joint wetting issues with Murata ceramic chip caps, in particular with Alpha UP78 no-clean paste? We are finding that changing either the paste or the vendor corrects this problem. If so, please advise your solution(

The Alpha EF-9301 flux worked great! We went from ~4 solder issues per PCB to

Hi all Recentlt I encounter a issue, the solder paste was not dry after wave. Mostly happen and the end of the board. It is rare case, 1 day happen about twice. But to achieve our quality target, I still need to overcome this issue. I use Alpha OM-

I have used SnBi from Alpha, and it worked well. The only issue I found is that you cannot have ANY Pb contamination.

I know this is not SMT related but would anyone care to comment on Alpha 856 flux, good/bad experiences or any known issues? I did some samples recently using it and had excellent results. Information on it seems a little hard to find and it makes

Attention Alpha users: I just read Alpha is going to close the US paste factories and move them to Mexico. Be on the lookout for quality issues when they do. I am sorry to see them go in this direction.

Please help to clairify the problem. Are we talking: * A pre-reflow [placement] problem? * A post-reflow [solder wetting] problem? Is the wetting issue that you mention related to the board or to the component? Please give us a little more detail

I have had Selective issues such as yours on two very different Selective Solder Machines. I was able to eliminate these issues by using Alpha EF-9301 wave flux with any SAC305 solder. It's a more aggressive flux, but really made the difference. Anot
