Agee with Hegemon. We also have two machines from ACE. They run most every day, all day. Good machines, great tech support. I would recommend the drop jet option for any no-clean operations as you'll need the extra concentration of flux to make i

I have seen problems similar to this caused by too high concentration of cleaning solution used in ultra-sonic cleaning process. If cleaning solution is used, make sure it is compatible with solder process. Also, improper mixing of fluxes and solde

Paste Flux / Reflow: Our experiments indicated that the combination of no-clean solder paste and air forced convection reflow produced the fewest tombstone defects, followed by water-soluble paste reflowed in air, and most tombstones occurring with

Hi Russ, assuming that only your flux changed and the PCB-finish stayed the same it seems to me that the solderability of that finish is somehow poor. About Ni/Au it can be said that the solderconnection is made between Ni and Sn. The Au-finish is ju

At my last company, we installed in-line testers. They worked very well, but there were some issues to be addressed; 1 - Boards had to be cool enough to go through ICT or we had false failures. 2 - We used no-clean flux...enough said about that. 3

We manufacture both bulk and localized ionic contamination testers. My answer is from the perspective of the cleanliness testing method. The issue with all bulk ionic contamination testers (Ionagraph, Omegameter, Zero-Ion), is that they test the en

How do yall monitor the concentration of yer saponifier? [NOTE: This is a BIG chance for NC flux-types to make smart remarks in retribution for remarks made about removing solder balls in an aqueous cleaner.]

In a Nut Shell.... Titration is used to maintain the Concentration level (Solids Content) of a liquid flux. Keeping the concentration level constent ensures repeatable fluxer & soldering performance. Specific gravity measurements can be used to do t
